prime numbers in c
#include<stdio.h> main() { int n, i, count=0; printf("Enter Number"); scanf("%d",&n); for ( i = 1; i<= n; i++) { if (n % i == 1) { count++; } } if( count == 2) { printf("Prime Number"); } else { printf("Not A Prime Number"); } }
prime numbers in c
#include<stdio.h> main() { int n, i, count=0; printf("Enter Number"); scanf("%d",&n); for ( i = 1; i<= n; i++) { if (n % i == 1) { count++; } } if( count == 2) { printf("Prime Number"); } else { printf("Not A Prime Number"); } }
prime no program in c
#include<stdio.h> int main() { int n,i; printf(“\nEnter the number : “); scanf(“%d”,&n); for(i = 2; i <= n/2; i++) { if(n % i ==0) { break; } } if(i > n/2) printf(“\n%d is a Prime Number\n”,n); else printf(“\n%d is not a Prime Number\n”, n); return 0; }
program to know if a number is prime
#include<bits/stdc++.h> using namespace std; bool Is_Prime(long long x){ if(x%2==0)return false; for(int i=3;i*i<=x;i+=2) if(x%i==0)return false; return true; } int main(){ long long x; cin>>x; if(Is_Prime(x))cout<<"Is Prime"; else cout<<"Is not Prime"; }
prime number c
#include <stdio.h> int main() { int i, num, p = 0; printf("Please enter a number: \n"); scanf("%d", &num); for(i=1; i<=num; i++) { if(num%i==0) { p++; } } if(p==2) { printf("Entered number is %d "\ "and it is a prime number.",num); } else { printf("Entered number is %d "\ "and it is not a prime number.",num); } }
prime number c program
int isPrime(int n) { for (int i = 2; i < n; i++) if (n % i == 0) return 0; return 1; }
c program to check prime number
//program to find prime number or not using c programming #include<stdio.h> #include<conio.h> // program starts from here after main() function void main(){ int n; int i,count =0; // count is incremented when the loop is true. printf("Enter the number\n"); scanf("%d",&n); for (i=1; i<=n; i++){ if(n%i==0){ count++; } } // for the prime number the no of count is 2 // number is divided by 1 or itself(given number) so count ==2 if(count ==2){ printf("%d is prime number.\n",n); } // for the composite number the number is divided by more than 2 number. else{ printf("%d is not prime number\n",n); } getch(); }
