Xcode unable to load program? Getting error: Thread 1: EXC_BAD_ACCESS (code=1, address=0x68)

Question

#include <stdio.h>
int main (void)
{
    int col1, col2;
    FILE *fname = fopen("1930_2001.txt" , "r");
    fscanf(fname , "%d" , &col1);
}

Whenever I try to get information from the data file, before I even do that, I get an error that it can't access the information. It says it's "NULL" and I have the file in the debug folder in Xcode of my project. Any help?

Answer 1

Have you put your data file and the compiled binary into the same folder? Xcode put the binary in somewhere not easy to find, you can Option+click the target name and choose "Show in Finder".

Or you can also compile your project using xcode-build CLI tool, or directly compile your program using clang, which saves you from lots of trouble.
