In this program, we will code to find the number is prime or not. A number is said to be a prime number if it has only 2 divisors 1 and the number itself. C++:
#include<iostream.h> #include< conio.h> #include<stdio.h> #include<math.h> void main() { clrscr(); int num,k=0; cout<<"Enter a number: "; cin>>num; for(int i=2;i<=num/2;i++) { if(num%i==0) {cout<<"It is not a prime number"; break; } else k++; } if(k>1) cout<<"It is a prime number"; getch(); }
Output:
Enter a Number: 17 It is a prime number
Python:
num =int(input("Enter a Number: ")) k=0 for i in range(2,num//2): if num%i==0: print("It is not a prime number") break else: k+=1 if k>0: print("It is a prime number")
Output:
Enter a Number: 17 It is a prime number
