7.Write a program in C to perform bitwise OR on two numbers using the '|' operator.

Bitwise OR Operator (|):
The bitwise OR operator is a binary operator that logically ORs each bit of two operands that are integers. When comparing the operands, it compares each matching bit, returning 1 if either bit is 1, otherwise returning 0. A single vertical bar or pipe symbol represents it, i.e., (|).
In C Programming , the bitwise OR operator is represented by the symbol |.
Let us explore the bitwise OR operation on two integers number 9 and 5.
9 = 1001 ( Binary)
5 = 0101 ( Binary)
Bitwise OR | Operation of 9 and 5
1001
| 0101
________
1101 = 13 (In decimal)

#include <stdio.h>
int main()
{
int p,q,ans;
// read the two numbers from user to perform bitwise or operation
printf("\nEnter any first decimal number: ");
scanf("%d", &p);
printf("\nEnter any second decimal number: ");
scanf("%d", &q);
// perform the bitwise OR | operation
res = p | q;
// Display the result
printf("\n Result after bitwise OR operation is: %d",res);
return 0;
}

a program in C programming language that asks the user to enter two numbers and perform bitwise OR | operation.

Output:
Enter any first decimal number: 9
Enter any second decimal number: 5
Result after bitwise OR operation is: 13
Explanation:
In binary system 9 is represented as 1001 and 5 is represented as 0101.
1. In this program example We declare three integer variables 'p','q' and 'ans' respectively.
2. The two numbers are accepted and stored in p and q variables using scanf() function.
3. Then the bitwise OR | operation is performed between `p` and `q` using the `|` operator. The result of the OR operation is stored in the variable `res`.
4. The result of the OR operation between 1001 and 1001 is 1101, which is equivalent to 13 in decimal.
5. Finally the the result of the bitwise OR (|) operation is shown using the printf() .
