I was sure that it makes a difference inside:
#include <stdio.h>
main()
{
int i;
printf("loop 1 should start with 0\n");
for (i=0;i<10;i++) { printf("%d\n",i); }
printf("loop 2 should start with 1\n");
for (i=0;i<10;++i) { printf("%d\n",i); }
}
But it doesn't. Sorry for the brainfarts of an old man.
