Here is very simple code,

using namespace std;
int main() {
    unsigned int u=10;
    int i;
    int count=0;
    for (i=-1;i<=         


        

Answer 1

On a system where an integer is stored in 4 bytes, I believe that the value of -1 equals the value of 2147483649 (1000 0000 0000 0000 0000 0000 0000 0001) - It's 1 with the MSB set to 1 to indicate it's negative.
