    Since you want to print the value of f, you should not be taking its address:
    Code:
    #include <stdio.h>
    
    int main( void )
    {
        int f = 2;
    
        printf("&#37;d", f);
    
        getchar();
    
        return 0;
    }

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
