How to randomize arrangement/order of output in C? (arrays)

[4102]

1. Homework Statement

Hi I'm using C and I need to use arrays on this one, but I need to somehow randomize the output.2. Homework Equations

for example an output "abcde" could also have an output "bcade" possible

3. The Attempt at a Solution

#include <stdio.h>

main()
{

char word[27] = "abcdefghijklmnopqrstuvwxyz";

printf("The contents of word[] is %c%c%c\n", word[0], word[1], word[3]);

}

the output of these one is "abc", but I want it to randomize it without rearranging the order of the output. In every run of the program, the order of the output should be diferent

example for every run, the output would be "bac" or "cba" etc.

Thanks!

Hello,

To randomize the output of your program without changing the order of the output, you can use the rand() function from the <stdlib.h> library. This function generates a random integer, which you can then use as an index to access a random element in your array.

Here is an example of how you can use this function to randomize the output of your program:

#include <stdio.h>
#include <stdlib.h> // for rand() function
#include <time.h> // for srand() function

int main()
{
char word[27] = "abcdefghijklmnopqrstuvwxyz";
int i, index;

// seed the rand() function with the current time to get different results each time
srand(time(0));

// loop through the array and print a random element from it
for(i = 0; i < 3; i++)
{
// generate a random index between 0 and 25
index = rand() % 26;

// print the character at the random index
printf("%c", word[index]);
}

return 0;
}

This code will print 3 random characters from the array in each run of the program. You can modify it to fit your specific needs.

Hope this helps!
