1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
#include <iostream> using namespace std; int main() { int Number, BitPositioning; /* Get the Number input */ cout << "Enter the Number:"; cin >> Number; /* Get the bit position input */ cout << "Enter the Bit position you want to set(Between 0-31):"; cin >> BitPositioning; /*Calculating the Bit_mask*/ int Bit_mask = (1 << BitPositioning); Number = Number | Bit_mask; cout << "The Number after set the bit in the given position is:" << Number; return 0; } |
Output
Enter the Number: 4
Enter the Bit position you want to set(Between 0-31): 1
The Number after set the bit in the given position is: 6

Output
Enter the Number: 4
Enter the Bit position you want to set(Between 0-31): 1
