    Can't resolve strcat

    I searched these forums and found many results for "strcat", and have been reading through them. However, after implementing what I have learned, I still can't get rid of this one warning message:

    [Warning] passing arg 2 of `strcat' makes pointer from integer without a cast
    Here is my code:

    Code:
    int mm;
    int input_length;
    char current_char;
    char *corrected_char = malloc(80); // user input without ">"
    input_length = strlen(aa[ii]);
    input_length = (int) input_length - 1;
    
    
    for(mm = 1; mm < input_length; mm++) {
            current_char = aa[ii][mm];
            printf("Character: %c\n", current_char);
            strcat(corrected_char, current_char);
            printf("New char: %c\n", *corrected_char);
                        
    }
    ii++;
    aa[ii] has a maximum size of 80 bytes. Each line in aa[ii] is something like ">hello" or any string, but it always begins with ">". What I am trying to do is strip the ">" and resave the string to a new variable, which would just contain "hello". Everything is working fine except for strcat(). I've tried making current_char a pointer but it doesn't work. Any ideas?

    Well what you could do is just:
    Code:
    strcpy(corrected_char, aa[ii]+1);
    Or if the line had some spaces at the beginning before the >, search for the >, then use that as the index:
    Code:
    strcpy(corrected_char, aa[ii]+index);
