Example: first prime numbers

#include<bits/stdc++.h>
using namespace std;
bool Is_Prime(long long x){
	if(x%2==0)return false;
	for(int i=3;i*i<=x;i+=2)
		if(x%i==0)return false;
	return true;
}
int main(){
	//first n prime numbers
	int n;
	cin>>n;
	int i=1;
	while(n--){
		while(!Is_Prime(++i));
		cout<<i<<" ";
	}
}
