C Programming language Exercises 1-1

Practice 1-1 running the "Hello, World" program in your own system. Then deliberately remove part of the program, to see what error messages will be obtained.

The code is as follows:

#include <stdio.h>    //     contains information about the standard library.  int main ()    //     defines a function named Main, which does not accept parameter values.  {    printf ("Hello, world\n");    //     The man function calls the library function printf to display a sequence of characters.     getch ();    // Prevent the console     from flashing through, you need to accept any characters after you close the console.     return0;    //     returns a shape to the execution environment, and 0 represents a successful execution. }

Personal Understanding:

As a classic Hello, the world program, each line of code is worth thinking about, you can go to browse the Stdio.h library has those functions.

When VS2013-type code is executed, the console flashes past, and VS2013 does not join the "Enter any key off" function in VC6.0.

Resolves the issue after adding the Getch () function.
