C-free 5 can only run the first program. If it is a program, you can compile and run multiple programs. If it is a project, you can only run one program.
The first answer to the question of the first program in C language is really nonsense. main (void) has no parameter and does not return the value of void main (). Do you see if it is # include and <stdio. h> there is no space between them. Some compilers do not need spaces, such as Qt Creator and vs2012, But I need spaces in keil. You can check if this is the reason, if not, send the cause of the error.
