Question

Write a program in C++ to print the prime numbers between 100-200.

Answer 1

#include<stdio.h>

int main()

{

int i,j,flag=0;

scanf("%d",&n);

for(i=100;i<=200;i++)

{

 for(j=2;j<=i/2;j++)

 {

  if(i%j== 0)

  {

   flag=1;

  }

 }

 if(flag == 0)

  printf("%d, ",i);

 flag=0;

}

return 0;

}

Answer 2

"The program in C++ programming language that will print the prime numbers between 100 and 200 is as follows:  

#include <iostream>

using namespace std;

int main()

{

 int low = 100;

cout << "Prime numbers between " << 100 << "and " <<  200 << " are: ";

  while (low < 200)

{

flag = 0;

    for (i = 2; i <= low/2; ++i)

      {

       if(low % i == 0)

        {

         flag = 1;

            break;

       }

}

       if (flag == 0)

           cout << low << " ";

       ++low;

   }

   return 0;

}"
