When I use Run code, I get normal output but when I use run C/C++ file I don’t get the desired output instead get a bunch of things written.
This is what I get in Debug console when running C program –

Hello Kaddu=thread-exited,id="2",group-id="i1"
The program 'C:UserspriyaOneDriveDesktopCodeCstartfile.exe' has exited with code 0 (0x00000000).

This is the output that I get –

This is What I get in terminal while running C++ program –

I have also attached screen shot of error which I get while trying to run C++ program.*
This is the first dialog box that I get.
This is what I get after clicking Debug anyway.

The code is a simple hello world code and there is no error in the code. I tried finding solution on Youtube and google but could not find anything helpful. I have tried to give all info that might help in resolving the issue but if I missed something important than I am really sorry for that. I hope to receive some assitance.

C program code –

#include<stdio.h>
int main () {
    printf("Hello Kaddu");
    return 0;
}

C++ program code –

#include <iostream>

int main() {
    std::cout << "Hello World!";
    return 0;
}
