Question

#include <stdio.h>
int main (int argc, const char * argv[])

{
    FILE *fp;
    fp=fopen("/Users/--------/Desktop/C.txt", "w");
    putc("C", "/Users/-------/Desktop/C.txt");
    fclose(fp);
}

Here is my simple code for writing the letter “C” into the textfile C.txt. I get the error code EXC_BAD_ACCESS every time I write it. Whats happeneing?

That’s not how putc should be used. Try:

putc('C', fp);

putc looks like this:

int putc(int c, FILE *stream);

You are passing a char * instead of a FILE *.
