Write A C++ Program That Will Display The Sum Of Prime Numbers From 1 To N?

#include<iostream.h>
#include<conio.h>

int GetPrime(int);

void main(){
int number=0;
cout<<"Enter a number to check:";
cin>>number;
int sum=0;

for(int i=1;i<=number;i++)
    sum=sum+GetPrime(i);

cout<<"Sum of Prime numbers:" <<sum;
getch();
}

int GetPrime(int number){

bool prime=true;
for(int i=2;i<number;i++){
    if(number%i==0){
        prime=false;
        break;
    }
}
if (prime)
    return number;
else
    return 0;
}
