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)
I have finished writing the code for the following program. I have concerns with the pseudo-code that I have written and the flow chart seems really complicated. I dont know how to build it. Here is the question:
An Internet service provider has three different subscription packages for its customers: Package A: For $9.95 per month 10 hours of access are provided. Additional hours are $2.00 per hour. Package B: For $14.95 per month 20 hours of access are provided. Additional hours are $1.00 per hour. Package C: For $19.95 per month unlimited access is provided.
Write a program that calculates a customer s monthly bill. It should ask which package the customer has purchased and how many hours were used. It should then display the total amount due.
Input Validation: Be sure the user only selects package A, B, or C. Also, the number of hours used in a month cannot exceed 744
Here is my program: #include <iostream> using namespace std; int main() { char package; int hours;
[code]....
What should be my pseudocode and flowchart ? Can i copy and paste my pseudocode here ?
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
Have an assignment due in a few weeks and I'm 99% happy with it My question is is there a method or process for reducing redundant code in nested loops. Ie my code compiles and runs as expected for a period of time and after a few goes it omits a part or prints an unexpected out ext so basically how to find when the redundancy occurs with out posting my code so I can learn for my self?
I am having trouble understanding what I need to do to halt the flow of a program until a video file finishes playing. So far I have accomplished getting the video to play, but the program continues while the video is playing rendering the content of the program on top of the video making it not seen.
My goal is to make the video play, then once it has finished the rest of the program should run.
So far I have this in the start up area of my code:
//Initialize components for DirectShow to stream a video at start-up CoInitialize(NULL); //creates filter graph manager
[Code].....
After this code runs once, the program proceeds immediately into the loop where my update and render functions for the program runs. Preferably, I want to stop just the render function while allowing the update to continue to check if the user presses a key to skip the video. What do I need to add to the code to do this?
I am attempting to write some code for a flow meter and LEDs using my Arduino. I need the flow meter to count a certain quantity of fluid, then light up an LED which corresponds to that quantity. I found this code on the internet and it was exactly what I needed but when I opened up the serial monitor to see if it worked it didn't. I have finally fixed the issue with it not counting anything at all, but it is still acting as if it was measuring the rate. how it counts and keeps track of how much fluid in total has passed through the flow meter ?
volatile int NbTopsFan; //variable to accumulate the number of pulses float Calc = 0; //the volume flowed since measurement started, liters void pulse() //This is the function that the interupt calls int hallsensor = 2; //The pin location of the sensor
const int led1Pin = 3; //pin for LED corresponding to volume1 const int led2Pin = 4; //pin for LED corresponding to volume2
I'm trying to write a code that takes two arrays from the user (presumably in ascending order) and then passes the sizes of both arrays and a pointer to each to a separate "int* mergeArrays" function that will merge sort the two. I've written a lot of the code, but I can't get it to compile. I get errors: lab6.c: In function "main":
lab6.c:31:14: error: expected expression before "int" mergeArrays(int* firstArray, int size1, int* secondArray, int size2); ^ lab6.c:31:14: error: too few arguments to function "mergeArrays"
I have a class 'A' which is almost perfect for my needs. Class 'B' uses class 'A' I've now designed Class 'C' and Class 'D' and noticed that there is a good chunk of code in class 'B', 'C' and 'D' for using Class 'A' is duplicated. I've separated out this code in specific, standalone functions in each of the classes. Now I'm wondering where this code should go. At the moment, the functions are duplicated in the three calling classes (B, C and D). Placing the functions into class 'A' would break the single responsibility principle. Inheritance to add functionality would likely break both SRP and LSP. The one that seems that it may work is composition.
However, Is designing a complete class just for a few functions over kill?
Would it be valid for classes 'B', 'C' and 'D' to access both the new class 'E' (which would depend on A) and the old class 'A' (which would have to be the same instance as the instance in the new class 'E'), or should the new class 'E' provide sufficient functionality so that Classes B, C and D don't need to access Class A directly? It would seem that its then an incomplete interface of the original object with additional functionality (ie, incompatible) Or should I do it a completely different way?
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; }
