# C++ Program to Print Prime numbers in a Given Range2 min read

In this C++ programming example, we will write a C++ Program to display Prime Numbers between two intervals. Let us start by understanding what is a prime number.

### Prime Number:

A Prime Number is a number that is only divisible by 1 and itself. Example: 2, 3, 5, 7, 11, 13, 17, etc. These numbers are only divisible by 1 and the number itself.

Note:
0 and 1 is not a prime number and 2 is the only even and smallest prime number.

To understand the following program, you should have a basic idea about the following topics in C++ programming.

## C++ Program to Print Prime Numbers

The program takes the user input for the starting number ( lower range) and the end number (upper range). Then prints all the prime numbers that fall within that range.

Also notice in the program that 0 and 1 are specifically checked to make sure that those two are not printed even if the lower range entered by the user is 0.

Output:

`Enter the lower range: 0Enter the upper range: 30List of Prime numbers between 0 & 30:2 3 5 7 11 13 17 19 23 29`

You can also print the prime numbers between 0 to any range or 100 using the same logic as above. You may go through the following program for more.
