    Trouble Accesing Array members

    Sorry for the many questions but am about to go nuts here. This worked in another project of mine but now it just keeps crashing my program.

    Here is the troubled code:

    Code:
    #include <stdio.h>
    #include <stdlib.h>
    
    int main()
    {
        int i,j,m,p, k;
        char* *setArray;
        char newsetArray[10];
        for(p=0; p<10; p++){
        newsetArray[p] = 0;
        }
        setArray = calloc(3, sizeof(char*));
        for(i=0; i<3; i++){
            setArray[i]=calloc(200, sizeof(char));
            printf("\nType your set:\n");
            gets(setArray[i]);
        }
        compare(setArray[0],setArray[1]);  <---------------Look here
    
        return 0;
    }
    
    int compare(char *c1, char *c2)
    {
    
        printf(c1[0]);  <------------------- and here
    
        return 0;
    }
    The trouble spot is in the red. Basically the function gets passed a string that's also stored in an array and then the function breaks down the string. (am about to compare the values). Now this worked before but now it keeps crashing. Now I tested it with this:

    printf(c1);

    And that confirm that the string is passed since it prints out everything. But I want to split up the string and don't understand why its causing these problems.

    Try printf("%c",c1[0]); or putchar(c1[0]); instead.

    How about posting the actual code that causes the problem?

    thanks man! That worked but now am wondering how come it worked up top without the %c. Right under the call to the compare function.
