How can I return a string to the operating system in my C code?

Question

I am a C beginner and this is my C code:

#include 
#include 

main()
{
    printf(\"Hello, World!\\n\");
    return \'sss\';
}

Sadly there is no way to do that.

You could add something to the end of your C program like:

int main()
{
    int err = 0; // 0 is "success" is most C programs
    printf("Hello, World!!\n");

    switch( err )
    {
      case 0:
        printf("Program shutdown successfully!\n");
        break;
      case 1:
        printf("We had an issue somewhere. Please fix your input data\n");
        break;
      //case 2, 3, etc...
    };

   return err;
}
