 Write a c program to print all prime numbers for 1 to n

example problem

#include<stdio.h>

void main(){

   int i, num, n, count;

   printf("Enter the range: \n");

   scanf("%d", &n);

   printf("The prime numbers in between the range 1 to %d:",n);

   for(num = 1;num<=n;num++){

      count = 0;

      for(i=2;i<=num/2;i++){

         if(num%i==0){

            count++;

         break;

      }

   }

   if(count==0 && num!= 1)

      printf("%d ",num);

   }

}

Output the prime numbers for 1 to n

Enter the range:50

The prime numbers in between the range 1 to 50:

2 3 5 7 11 13 17 19 23 29 31 37 41
