Question

program to find sum of first fifty prime even number. ​

Answer 1

Answer:

Program to find the sum of first fifty prime number.

Explanation:

Code of the above program:

#include <stdio.h>

int main()

{

  int i, j, isPrime, sum=0;

     int n= 50 */  you can also initiate in the for loop rather than defining    here   */

     

     /* Input upper limit from user */

   printf("Find sum of first fifty prime between 1 to n: ");

   scanf("%d", &n);

   /* Find first fifty prime numbers between 1 to n */

   for(i=2; i<=n; i++)

   {

       isPrime = 1;

      for(j=2; j<=i/2 ;j++)

       {

           if(i%j==0)

           {

               isPrime = 0;

               break;

           }

       }

       if(isPrime==1)

       {

           sum += i;

       }

   }

printf("Sum of first fifty prime numbers between 1 to n %d = %d", n, sum);

  return 0;

}

Answer 2

class s1upv

{

public static void main ()

{ int s= 0;

for (int i= 0 ; i<= 50 ; i++)

{ for (int j=0 ; j<= i ; j++)

{ if ( i% j = = 0 && i%2 ==0)

{s = s+ i ;

}

}}

system .out.println ( "sum is :"+ s );
