How do you write a program to find first 50 prime numbers using C plus plus?

Answer 1

#include <iostream>

bool isPrime(int p)

{if( p<=1 ( p>2 && p%2==0 ))return( false );int max = (int)sqrt(( double ) p ) + 1;for( int i=3; i<=max; i+=2 )if( p%i==0 )return( false );return( true );

}

int main()

{

const int max=50;int primes[max];

int count=0, num=0;

while( count!=max )

{num+=num>2?2:1;if( isPrime(num) )primes[count++]=num;}for( int i=0; i<max; ++i )std::cout << primes[i] << std::endl;return( 0 );

}
