How to produce 64 bit masks?
- by egiakoum1984
Based on the following simple program the bitwise left shit operator works only for 32 bits. Is it true?
#include <iostream>
#include <stdlib.h>
using namespace std;
int main(void)
{
long long currentTrafficTypeValueDec;
int input;
cout << "Enter input:" << endl;
cin >> input;
currentTrafficTypeValueDec = 1 << (input - 1);
cout << currentTrafficTypeValueDec << endl;
cout << (1 << (input - 1)) << endl;
return 0;
}
The output of the program:
Enter input:
30
536870912
536870912
Enter input:
62
536870912
536870912
How could I produce 64-bit masks?
