#include <stdio.h> int main () { / * My first C program * / printf ( " the Hello, World \ the n-! " ); return 0; }
Living Example:
- All C language programs need to include the main () function. The code from the () main function begins execution.
- / * ... * / for explanatory notes.
- printf () for formatting the output to the screen. printf () function in the "stdio.h" declaration header file.
- stdio.h is a header file (standard input and output headers), #include is a preprocessor for introducing header. When the compiler encounters printf () function, the If you do not find stdio.h header file, the compiler error occurs.
- return 0; statement is used to indicate exit the program.
