Question

All I simply want to do is a make a record that starts with C or D randomly and has a number along with it 1-10. so a record would be C10. Can anyone tell me what I am doing wrong here?

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/wait.h>
#include <time.h>
#include <unistd.h>
#include <sys/types.h>

/*

 */
int main(int argc, char** argv)
{
    char letter[] = { 'C', 'D' };
    char record[2];
    int r=1;
    while (r < 11)
    {
            char num;
            num = r;
            record = (letter[rand()%2],num);
            r++;
    }
 return 0;
}

Answer 1

record = (letter[rand()%2],num); 

This is not a legal opporation… try this:

record[0] = letter[rand()%2];
record[1] = num;
