strtoull and long long arithmetic

Question

Can anyone explain the output of this program and how I can fix it?

unsigned long long ns = strtoull(\"123110724001300\", (char **)NULL, 10);
fprintf(stderr,         


        

Answer 1

I cannot explain the behavior. However, on 32 bit Windows XP with Cygwin gcc-4.3.2:

#include 
#include 

int main(void) {
    unsigned long long ns = strtoull("123110724001300", NULL, 10);
    fprintf(stderr, "%llu\n", ns);
    return 0;
}

prints

E:\Home> t.exe
123110724001300
