# Swift program to perform the bitwise OR operation

Here, we are going to learn how to perform the bitwise OR operation in Swift programming language?
Submitted by Nidhi, on June 03, 2021

Problem Solution:

Here, we will create two integer variables then we will perform the Bitwise OR (|) operation between both variables and print the result on the console screen.

Program/Source Code:

The source code to perform the bitwise OR (|) operation is given below. The given program is compiled and executed successfully.

// Swift program to the
// perform bitwise OR (|) operation

import Swift;

var num1 = 5;
var num2 = 2;
var res = 0;

res = num1 | num2;

print(res);

Output:

7

...Program finished with exit code 0
Press ENTER to exit console.

Explanation:

In the above program, we imported a package Swift to use the print() function using the below statement,

import Swift;

Here, we created two integer variables num1 and num2 that are initialized with 5, 2 respectively. Then we performed the bitwise OR (|) operation between the num1 and num2 variables. After that, we printed the result on the console screen.

Evolution of expression:

res = num1 | num2
res = 5 | 2

The binary equivalent of 5 is 101.

The binary equivalent of 2 is 010.

Then

101
010
====
111

That is 7.
