Write a C, C++ program to print prime numbers between 1 to 100.

A prime number is a number that is greater than 1, and there are only two whole-number factors 1 and itself.

Example of prime numbers are - 2, 3, 5, 7, 11, 13, 17, 19, 23 etc.

Program to Check whether Number is Prime.

Search Algorithm (Linear and Binary Search).

## C Program to Print Prime Numbers Between 1 to 100

#include<stdio.h> int main() { int i=2,j,p; while(i <= 100){ /* Initially P is 1. */ p = 1; for(j = 2; j < i; j++){ /* Check if it is divisible by any other number, other than 1 or itself. */ if(i % j == 0){ p = 0; } } if(p) { printf("%d ",i); } i++; } return 0; }

**Output :**

2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97

## C++ Program to Print Prime Numbers Between 1 to 100

#include<iostream> using namespace std; int main() { int i = 2, j, p; while(i <= 100){ /* Initialize P */ p = 1; for(j = 2; j < i; j++){ /*if it is divisible by any other number, other than 1 or itself then it's not a prime number. */ if(i % j == 0){ /* If it's not a prime, Set p=0 . */ p = 0; } } /* Print prime number. */ if(p) { cout << i << " "; } i++; } return 0; }This program illustrated, how to print prime numbers between 1 to 100. If you want to print

**Prime Numbers between 1 to n**, take n as a input from user and use the same logic which we used while printing prime number between 1 to 100.
