Have a blast at The Ping Page, which has a link to full source on the original Unix ping(8).

Thanks! It has a lot of legacy code that makes it not work properly with modern C compilers. Is there an updated source code for ping? – Gossip

Answer 4

#include <iostream>
using namespace std;
int main() {
int x = system("ping -c1 -s1 8.8.8.8  > /dev/null 2>&1");
if (x==0){
    cout<<"success";
}else{
    cout<<"failed";
}

replace 8.8.8.8 from your IP Address
