Write a program that will ask the user to enter some words followed by the word END.
Input the words into an array and then output the following statics:
the list of and the count of how many words were typed (not counting END) -- Test 2 the list of and the count of how many unique words were typed -- Test 3 the list of sorted unique words (in alphabetical order) -- Test 4 the list of sorted unique words along with frequency counts for each word -- Test 5 See the sample run below:
Please type in some words. Type END and return when you are finished. red green blue RED red blue green blue orange red reg apple banana banana END
You typed the following 14 words: red, green, blue, RED, red, blue, green, blue, orange, red, reg, apple, banana, banana
You typed the following 7 unique words: red, green, blue, orange, reg, apple, banana
Here are those same unique words sorted: apple, banana, blue, green, orange, red, reg
Here are those same unique words sorted with a count of how many times each was used: apple: 1 banana: 2 blue: 3 green: 2 orange: 1 red: 4 reg: 1
I am having problems understanding where this code is wrong as I believe that I am not receiving the correct outputs. I have truncated the code to the most pertinent.
The algorithm asks that every value in array1 be divided by array2
and if that value is less than the ratio * array3 (percentage filter) then output.
I have no problem with the code with the exception of abs(ratio*array3[m]
Assuming that the ratio = 1 then all values get outputted, I want the array1 (first value) to have the first value in array3 assigned to it, the second value in array1 to have the second value in array3 to be assigned.
So:
array1 (1.0) with array3 (0.05) array1 (2.0) with array3 (0.06) etc. or array1 (1.0) with array3 (0.05) array1 (3.0) with array3 (0.07)
Im having trouble with the while loop, this program should ask the user for their name, if incorrect it should send an error msg and ask for input again...after the correct name is entered the program should prompt the user to enter a password, again if incorrect it should send an error msg and ask for input again.
the code below does what it should when asking for a name..HOWEVER it does not allow the user to enter a password and instead jumps straight to the error msg..
#include<iostream> #include<string> #include<iomanip> using namespace std; int main() { // Variables string username; string password;
[Code] .....
After the correct name is entered, the program displays this:
"Welcome, Sadia Rajput." "To continue, enter your password: That is incorrect, enter password: "
I would prefer to do this using the while loops and not bool statements
My program will scan a message sent over Steam (An online game distributor ) and I want it to check if the Message contains one of the elements in the array. I want it to compare the String of the message to the values in the String array. I have tried looking into it but have unfortunately found nothing that would go along with my program outline. Here is my code so far:
if (add == true) { string[] itemNames = { "keys", "tickets", "nametags", "descriptiontags" }; string[] splitmessage = message.Split(' '); foreach (string word in splitmessage) { int strNumber;
[Code] .....
I am hoping for this to look like the picture of the code I wrote in the Attachments. [URL] .....
I have a homework assignment in C++ where I have to: "Write a program which asks user to input 10 students names. Store them in an array. Convert all the names to UPPERCASE without using any built-in functions. You must write the function to do that yourself. Lastly, sort the name in alphabetic order."
Here is my code so far, but my program won't compile, and the message it gives me is gibberish.
#include <iostream> using namespace std; void sortNames(string name[], int cap); void toUpper(string name[]); int minIndex(string name[], int i); void sort(string name[]); void swap(string name[], int i, int j);
Write a function to read and display the contents of names and marks. You then ask the user for a name and using the linear search return the index to the user. If -1 is returned then the name is not in the file. Otherwise write out the name and mark for that student.
Next, sort the arrays, write them out and then ask the user for a name to search for. This time use the binarySearch to return -1 or an index. Display the student's name and mark if found.
void getNames(ifstream& inStream, string names[], int marks[], int numElts); int linearSearch(const string names[], int numElts,string who); int binarySearch(const string names[], int numElts,string who); void selectionSort(string names[], int marks[],int numElts); void displayData(const string names[], const int marks[], int numElts); [Code] ....
Now I have worked up some stuff in parts but I am so lost and confused with these specific requirements: Previous questions asked me to sort out a linear search, a binary search and
LINEAR SEARCH:
int searchList(int list[], int numElems, int value) { int index = 0; // Used as a subscript to search array int position = -1; // To record position of search value bool found = false; // Flag to indicate if value was found
I'm looking to take in an array of less than 50 strings, and I want to find all of the unique words in that array (omitting the words that are repeated) and then outputting the unique words and unique word count. My code compiles, but my unique array is couting all of the words contained in the original array regardless of uniqueness.
#include <iostream> #include <string> #include <stdio.h> #include <string.h> using namespace std; int main() { cout << "Please type in some words." << endl; cout << "Type END and return when you are finished." << endl;
[code].....
This is what I get back.
You typed the following 14 words: red, green, blue, red, red, blue, green, blue, orange, red, reg, apple, banana, banana, END,
You typed the following 0 unique words: red, green, blue, red, red, blue, green, blue, orange, red, reg, apple, banana, banana, END
I'm not worried about the unique count yet, I just want to get the unique array containing the correct strings.
how do I tell the if statement to output this error message 'exceeded the maximum amount of characters' that has its characters stored in an array using c-style string?
[INPUT] The cat caught the mouse! [OUTPUT] Exceeded the maximum amount of characters (max 10) #include<iostream> #include<string>
I have a firmware application that works well where I display simple text messages on an LCD screen. At the moment, the User Interface is only in English and I have the text strings simply declared as follows:
I want to add a variable that can set the language dynamically from an external device, and so I thought I could do the following:
Code: #define ENG 0 #define FRE 1 #define GER 2 //... static char msg1[ENG][] = " Welcome "; static char msg2[ENG][] = " Data Read ";
[Code] .....
writeLCD(msg1[cLang][]); When I try to compile the above I get a compiler error at the "static char msg..." declarations. The error is: "error: array type has incomplete element type"
Is this method valid, but I have a simple syntax problem with the arrray declarations? Or is this method unworkable and I should find a different method?
I define "Comwords" as a string, but apparently it takes the members as chars, then I can't set strings in a structure equal to the chars.
I see to also be having unknown problems with the ComMAL array and loading it values into another element of the same structure.
How to correct this? I was thinking of casting char elements as strings, but could find no reference in my library book regarding how to do that (lots on casting int's a doubles...)
Code:
int _tmain(int argc, _TCHAR* argv[]) { int comm = 10; int targ = 5; int death; struct AI_WORDS
Using a for loop, construct two 100 element arrays, x and y, such that element i of x stores the value sin(2*pi*i/100)) and the corresponding element of y stores cos((2*pi*i/100)). Print the values stored in the elements of x and y as you calculate them.
I have attempted to solve it but I'm not sure why the value 0 is only being printed, maybe I haven't assigned sin(2i/100)) and cos((2i/100)) to the arrays properly?
Code: #include<stdio.h> #include<stdlib.h> #include<math.h> int main () {
I have an assignment that calls for a C program using a for loop AND a while loop that will receive an integer (called daNumba) and double it -- Using the integer the program will call the sumFor function and then the sumWhile function. These functions will both sum the values from daNumba to (daNumba * 2) ifdaNumba is positive. If daNumba is not positive it will add the values from (daNumba*2) to daNumba. Both functions will receive the value of daNumba and return a summed value. The only difference between the 2 functions is that sumFor will only use for loops and sumWhile will only use while loops. We are not to use arrays.
The program compiles without error. So far my while loop works for positive integers, but not with a negative integer (I have it commented out) I cannot get the for loop to work properly This is what I have so far -- I am stuck....
Code: #include<stdio.h> #include<stdlib.h> #include<math.h> int main () {
int main ( int argc, char *argv[] ) { int P[150] = {}, i, j; for ( i = 2; i <= 150; i++ ) {
[Code] .....
Using gdb, I noticed that the variable j keep going back to initial value after the interior for loop condition returns false. Why doesn't this for loop terminate right away?
I've just started learning the C language, and I'm stuck on something that is probably quite simple.how to get IF statements working within WHILE loops. My code is below. I am trying to write a program to count the number of words in a sentence, and obviously stop counting after a full stop has been entered. I created a variable called 'spaces' which will increase by one after the user enters a space. However, when the IF statement is in place, the loop never terminates, even if I enter a full stop. When I delete the IF statement, the loop functions correctly.
Code:
#include <stdio.h> int main() { char x; char a; char y; int spaces = 0; }
What output would you expect from this program?" The output was not what I expected. I've psuedo-coded this out and I'm still missing something.
Code:
#include <stdio.h> int main () { int numbers[10] = { 1, 0, 0, 0, 0, 0, 0, 0, 0, 0 }; int i, j; }
[code]....
The output: Code: 1 1 2 4 8 16 32 64 128 256 So when I look at this first loop I see that j = 0, which is less than 10, so then the program statement should commence, which is another for loop. So in this inner for loop I see that i = 0, which is not less than j, so this loop should terminate. Then the value of j increments by 1 and the first go around of the loop has completed.
Now I see that j = 1, so this is less than 10, and the inner for loop commences once again. This time though, i actually is less than j, so numbers[1] = numbers[1] + numbers [0], or numbers[1] = 0 + 1. Now the value of i is incremented by 1 and the first go around of this inner loop has completed. Then the value of j increments by 1 and another go around of that loop has completed.
So now j = 2, i = 1, and numbers[2] ( which is 0 ) = numbers[2] + numbers[1], or numbers[2] = 0 + 1. I was expecting the output to be an array full of 1's. However this is not the case..
I need to make a for loop without: using the math functions like pow, sqrt, etc. or an if-statement.I can only use the basic arithmetic functions like +,-,*, and.The for loop needs to display: 1,2,4,8,16,32,64,128,256,512,1024,2048,4096,8192 as the result
How do I make it so my loop works? This is what I have and it doesn't work...and I have no clue how to continue...
k = 0; //k is an int and I have declared it in the beginning of my code for( k = 0; k < 13; k++ ) { printf ( "%d, ",k ); k = k * 2; } printf("%d", x);
I just want to say that I just started learning the language and this is my very first shot at writing a simple program that is not "Hello World" So I recently learnt the basics of the if statement and how to loop in a console application, here's what it looks like:
namespace Testing_IF_Statement { class Program {
[Code].....
And again, this is just what I wrote in a few minutes without putting any thought into it.
Questions: 1)I have heard that the way I'm looping by using the goto statement is considered quite ancient, why is this and how else could I loop the program?
2)I declared a as an integer and asked the user to type 1,2,3,4 to perform mathematical functions, but when I tried declaring a as a string and searching if a == "PLUS" etc it would throw an error. Is there any mistake in how I approached this?
3)I know this is a bit premature to ask, but instead of writing _________ in the console to separate the loop is there any professional way to add a separator?
im trying to make a program which will tell which key i pressed and then it will print in msgbox, but i cant figure out how to read the key in loops, like i tried getasynkey (imported to my c# console app) with value around -32676 or -32767 i ( i found it on internet) and it only shows the key once, i want to do like while my key is pressed, then it will spam my console with key pressed, is there any way to do it?
Parts of this program are missing. The last few lines are confusing, since the variable 'a' gets incremented then decremented. But there are no loops. I understand that the value of 'a' is passed to 'c' before 'a' is changed in both cases.
But where, and when, do the changes take place? Is the decrement ever processed? Is there a better way to write these lines?
Code: main(){ int a = 21;int b = 10;int c ; c = a++; cout << "Line 6 - Value of c is :" << c << endl ; c = a--; cout << "Line 7 - Value of c is :" << c << endl ; return 0;}
i am trying to write program that prints out full lyrics to 99 bear song. Hoping for explanation or anything
The output would have to look like:
99 bottles of beer on the wall, 99 bottles of beer.
Take one down and pass it around, 98 bottles of beer on the wall.
My try below:
Code: #include <iostream> using namespace std; int main() { for(int i=99; i>=0 ;i--) cout << i <<""<< " bottles of beer on the wall, "<<i<<" bottles of beer."<<endl; for(int j=98; j>=0 ;j--){ cout <<endl; cout << "Take one down and pass it around," <<j<<" bottles of beer on the wall."<<endl; } return 0; }
I'm trying to make a program that prints a rectangle using "*" asterisks. I am only allowed to use "for loops" and I simply cannot get this to work properly. Here is my code so far...
Code: int main(void) { //RectangleSize represents the area of the rectangle(width*length) int length, width, RectangleSize;
