when try to run something, permission denied on mac terminal

Question

i compiled a c code and when I try to run it with ./ command, it gives me -bash: ./hw : Permission denied . please help me. note : i use Mac os Mojave.

C code:

#include <stdio.h>

int main()
{
    int n;
    FILE *ptr;
    ptr = fopen("input.txt", "r");
    fscanf(ptr,"%d", &n);
    printf("%d",n);
    fclose(ptr);
    return 0;
}

Compile command:

gcc -c hw.c -o hw

Try the command chmod +x hw. This will changes the permissions on the file to allow execution. You should then be able to run it with ./

How are you compiling the program? – wc_coder Oct 22 '18 at 18:46

`gcc -c hw.c -o hw` the code is : `#include int main() { int n; FILE *ptr; ptr = fopen("input.txt", "r"); fscanf(ptr,"%d", &n); printf("%d",n); fclose(ptr); return 0; } ` – Doruk Başıbüyük Oct 22 '18 at 19:05

you are just creating an object file (.o) not an executable.

try compiling with

gcc hw.c -o hw
