Thread: A piece of code activates only once at start of the program

Of course. But I'm not sure I understand what you mean.

Code:

#include <stdio.h>

int main()
{
    printf("Hello\n");  // happens once, then never again

    for (int i = 0; i < 10; ++i)
        printf("%d\n", i);

    return 0;
}
