Prime number program in C using recursion?
//Program to check number is prime or not using recursive function #include<stdio.h> #include<stdlib.h> void prime(int num,int count) { if(count<num) { if(num%count==0) { printf("%d is not Prime Number\n",num); goto exit; } count += 1; if(count<num) { prime(num,count); } } if(num==count) { printf("%d is a Prime Number\n",num); } exit: return 0; } int main() { system("cls"); int gvar; printf("Enter the number = "); scanf("%d",&gvar); prime(gvar,2); printf("\nashokakhil@gmail.com\n"); system("PAUSE"); return 0; } I think this can be another solution #include<stdio.h> #include<conio.h> int prime(int); main() { int i=1,r; clrscr(); r=prime(i); if(r==1) printf("\n\n\tNo is prime "); getch(); } int prime(int i) { int n=1,ans,flag=1; i++; ans=n%i; if(ans==0) { printf("\t\t\n\nNo is not prime"); flag=0; return flag; } if((i!=n-1)&&(n!=1)) flag=prime(i); return flag; }
What is prime factors numbers?
Every positive integer greater than 1 can be expressed as the product of a unique set of prime factors. The count of these factors is the prime factors number for the number.
