[FIXED] Netbeans C++ Weird output

Issue

#include <iostream>
using namespace std;

int main(){
    cout<<"Hello World!"<<endl;
}

I recently installed netbeans 12.0 and when I compile the code above, it says some weird words and numbers and a letter 'H'.

Also the words using, namespace, cout, and endl are underlined and when I hover to it, it says:

unable to resolve identifier + 'word'

This is the output:

PSID=1493                                                                       
NBMAGIC=1492                                                                                                                                                   
H                                                                               
RUN SUCCESSFUL (total time: 101ms)                 

Solution

As @user4581301 specified that the programs runs and immediately quits so you are not able to see anything. So, we need something to pause the program.

#include <iostream>
using namespace std;

int main(){
    cout<<"Hello World!"<<endl;
    system("pause");
}
