31.
Your long has only 32 bits.

You are confusing long and long long. This is C, not Java. The
suffix for a long long constant is LL, not L.
Very thanks, LL and %lld are the solution. The GCC compiler has not
bugs that i said.

Sure? My program is a testsuite of why the long type doesn't work, no
why my program doesn't work.

The constant overflows
Hi people,

#include // it's for public domain by J.C. Pizarro, hahahahaha
int main() {
long long int a,b,c;
unsigned int hi_a,lo_a,hi_b,lo_b,hi_c,lo_c;
a = 100L; // 10G
b = 1L; // 100M
c = a * b;
hi_a = (((unsigned
