C :: Function Which Takes A Character Array And Reverses It
Dec 7, 2013
Write a c function which takes a string(as a character array, null terminated) and reverses it. it doesn't print the reversed string -- it modifies the given string so that it is reversed.
I have to make a program that takes several numbers into an array into a function, and send them back into the main function multiplied by 1.13. This is what I have so far:
#include <iostream> using namespace std; void connell(int&n[20]) main() { int num[20];
[Code] ...
I do not know how to get numbers from an array from a main program to a function.
I have to write a function Subtracts val from each character in the array
// If the array is: abcdefghi and value = 5, then result is: 5 ascii characters subtracted from the given array // note: Make sure the character remains in the ' ' // to '~' (inclusive) // If character < ' ', then add 95 // If character > 126, then subtract 95 // to put back within the range, and repeat as needed // all printable characters are between this range // ' ' is the 1st printable character (32) // '~' is the last printable character (126) note: subtracting values from the char will cause an overflow.
the prototype is: void subtracting(char array[], int size, int value)
I'm trying to make a character array, and be able to custom fill it by using the scanf() function to ask the user for each character spot in the array.
Code: #include <stdio.h> int main() { int i; char character_array[11]; char *charpointer; charpointer = character_array;
[Code] .....
And this is the output i get when i run it:
Code: root@kali-Tulips:~# ./myown what letter would you like in the [0] spot of the array? : a what letter would you like in the [1] spot of the array? : what letter would you like in the [2] spot of the array? : b what letter would you like in the [3] spot of the array? : what letter would you like in the [4] spot of the array? :
[Code] .....
Obviously I'm trying to grasp C programming and am very new. I don't understand why this isn't working, and i think its more than my lack of knowledge of C syntax. I believe the correct memory is allocated but when examined with gdb i don't find what i expect....
In the function *expandArrayList and *trimArrayList I need to allocate either more memory or less memory to the given array. Right now I am using malloc on a new array and then transferring the elements of the original array to the new array, freeing the original array, and then reassigning it to the new array so it's size and capacity are either bigger or smaller than the original. I feel like there has to be a simpler way to do this with either realloc or calloc, but I cant find sufficient information on either online. Would I be able to use either to make this easier and the code cleaner?
Also, these are character arrays that contain several character arrays inside them, so I was wondering what the best way to transfer the contents of one array to the other would be. I have gone between
Code:
//example for (i=0; i<length; i++){ newarray[i] = oldarray[i]; } and Code: for (i=0; i<length; i++){ strcpy(newarray[i], oldarray[i]); }
but I'm not sure which one (if either) should work.
The 'ArrayList.h' file that is included contains the structure ArrayList, as well as the function prototypes for the functions listed below.
Here is the structure in ArrayList.h:
Code:
#define DEFAULT_INIT_LEN 10 typedef struct ArrayList { // We will store an array of strings (i.e., an array of char arrays) char **array;
I keep getting this error in my code. I believe it is because to use pow(x,y) both x and y have to be double, but how do i put that into my formula under calculations?
#include <iostream> #include <cmath> #include <iomanip> #include <string> #include <fstream> using namespace std; int main() { // Declaration section: Declaring all variables.
We have to write a function named fibonacci that takes an int indicating the length of the series and then store it in an array of size 20 printing the sequence from largest to smallest. Here is the small bit i have so far:
#include <iostream> #include <iomanip> using namespace std; void Fibonacci( int ); int main( ) {
[Code] ....
I just need something to get me on the right track.
I have a school project in which need to create a function that takes a File Object as a Reference Parameter. Supposedly, it should allow me to read the first piece of data from others separated by a space from a file. The later be able to continue reading from the next piece of data.
I know how to set things up to read from the data file, such as using
Write a function that takes two input arguments and provides two separate results to the caller, one that is the result of multiplying the two arguments, the other the result of adding them.Since you can directly return only one value from a function, you'll need the second value to be returned through a pointer or reference parameter.
How do I Write a function that takes two linked list as input arguments these linked list contain numbers like this:
num1->3->5->2->NULL (assuming that number 1 is 352) num2->4->3->9->1->NULL (assuming that number 2 is 4391)
The function should return 1 if num1 points to a linked list which represents a smaller number than the number pointed to by num2 linked list. Otherwise, it returns -1. If both linked list point to exactly the same number, returns a 0.
I was required to write a program that takes a baseball players statistics and displays there averages. I was required to make 3 function in the file to perform this tasks. my problem I am having a division problem in the SLG function. My compiler does not require the system ("PAUSE"); command.
OUTPUT The player's batting average is: 0.347 The player's on-base percentage is: 0.375 The player's slugging percentage is: (test)AB = 101 (test)Tot Base = 58 0.000
Code: /* Batting Average Program file: batavg1CPP.cpp Glossary of abbreviations: BA = batting average PA = plate appearances H = hits BB = bases on balls (walks)
Point p1(100,100); Point p2(300,200); Graph_lib::Rectangle r(p1,p2);
And also I have a function that takes a rectangle and returns a Point of that, say, top-left corner of that rectangle. For example:
Point N(Graph_lib::Rectangle R1);
My question is that, first, how to send that Rectangle r(p1,p2) to the Point N(Graph_lib::Rectangle R1) function? And then, how to return a Point from that function?
The program should store a character array in reverse order then display the reversed array. I have also included in the code that will display the actual characters into the array as it loops through. So I know the characters are being stored, but why doesn't it display the entire string when I call it?
I am currently having an issue with validating user input for a state abbreviation. I have an array where a list of abbreviations is stored to use as a comparison for whatever the user inputs. I have been able to get the list loaded properly but whenever i go to compare, it always comes back as true even if it isn't. Here is some relevant code:
static char stateTable[STATE_TABLE_SIZE][STATE_SIZE]; int main() { char buffer[40], *testCustName[40], testState[5], testCode; buffer[0] = ' '; int quit = 0; int p = 0;
I have a multiple choice function below that is part of a larger program but I am having trouble having it operate with characters as inputs and arguments. It has to be a character input, but I kinda want it to act like an integer, how do i do that?
Code: void addition(int *Preward) //function that is called by the users selection { int random1, random2; int order; int one, two, three; int rando1, rando2; char a, b, c; // ERROR
I am suppose to make a program that when the user is asked "Enter a Letter for the day:" if the user enters M or m then the screen will output "The day of the week is Monday" and so on until Sunday. I looked over my code and everything looks right but I still get errors saying Missing terminating character " and int function main error.
#include <iostream> using namespace std; int main() { char day; cout << "Enter a letter for a day of the week: ";
I want to move a character in a 2D array This Character should move vertically in a 2D Array To exemplify it for Exam in Snake Game A character automatically moves Please Write a example code that works
this function subtracts a given value for each element in an array. I If the array is: hellohowareyou, and the value is 6 then result will be : 6 characters from each letter in the initial array
and the prototype of it is:
void minusFromArray(char arr[], int size, int value);
how do i convert each element in the array into ascii and subtract the values from those ascii characters?
I'm having a little trouble writing program that on remove all repeat characters and leave only the non repeated characters. This is want I have so far.
