So I was trying out the Linux C++ compiler and this happened while compiling the following code:
#include <iostream>
using namespace std;
int main(){
cout<<"Hello World!\n"<<endl;
return 0;
}
ceibal@ceibal:~$ gcc HelloWorld.cpp

I tried with the same program but on C and it worked perfectly, but as soon as I translated it to c++ this occurred.
