Hi,
I was trying to make a function called show_binary() that would display the binary representation of the unsigned integer sent to it in its parameters. Here is my code:
#include
#include
using namespace std;
void show_binary (unsigned int num);
int main() {
unsigned int i = 0;
cout << "Enter an integer: ";
cin >> i;
cout << '\n';
show_binary(i);
return 0;
}
void show_binary (unsigned int num) {
unsigned int x;
for (x = (pow(2.0, (int) (sizeof (unsigned int))*8)) ;x > 0;x /= 2){
if (num&x) cout << "1 ";
else cout << "0 ";
}
}
When I ran this in the Visual Studio Command Prompt, the FOR loop did not run and nothing was displayed by the function. However when I lowered the initial value of x to only show 24 or less bits of the integer, it worked fine. I even tried putting 4,294,967,296 (2 raised to 32) and had the same result. Visual Studio uses 32 bit integers and "pow(2.0, (int) (sizeof (unsigned int))*8)" does in fact result in 4,294,967,296 so this should work.
Any suggestions?
