Jumping into C++ problems

Hi, I have written the code of the question "Design a program that finds all numbers from 1 to 1000 whose prime factors, when addedtogether, sum up to a prime number (for example, 12 has prime factors of 2, 2, and 3, which

sum to 7, which is prime). Implement the code for that algorithm."

the code is

Code:

#include <iostream>

using namespace std;

bool isdivisible(int z,int i)

{

return z%i==0;

}

bool (isprime (int z))

{

for (int h=2;h<z;h++)

{

if (isdivisible(z,h))

{

return false;

}

}

return true;

}

int main()

{

for ( int k = 2;k<10; k++)

{

int i=2;

int y=0;

int x;

x=k;

while(i<=x)

{

if (x%i==0)

{

x=x/i;

y=y+i;

}

else

{i++;}

}

int z;

z=x+y-1;

if (isprime(z))

{

cout<<k<<endl;

}

}

}

the problem is that the console window cant display all the results. It omits the 1st few result. How can I increse the space so that it can display all the results?
