No output when running program

Question

I had a issue with running a c-program. I am using Turbo C++ compiler but when I write a code and compile there is no problem with compiling. But when I run program is doesn't display any output.

This is the code:

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

Answer 1

let me solve your problem,buddy.

Problem: program doesn't display the output.

Reason:

Program execution takes milleseconds to display the output & turbo c++ compilor has not control over it. So, it's the responsibility of coder to control the execution to display the output.

Solutions:

1.using getch(); //it is predefined function of <conio.h>

2.using getchar(); //it is predefined function of <stdio.h>

Using getch();

Code:

 #include <stdio.h>
    #include <conio.h>
    
    int main()
    {
      printf("Hello world\n");
      getch();                  //it can be used to hold program execution,it wait until the user enters a character.
      return 0;
    } 

USING getchar();

Code:

    #include <stdio.h>
    int main()
    {
      printf("Hello world\n");
      getchar();                  //getchar() means get a character from user,if user press any key + enter then getchar() executes.
      return 0;
    }
