Self-taught C language-1

1. The standard method of creating a C program is a letter + number;

2. Empty project Nothing can be generated, so will not return the failure, will show the compilation success;

3.cpp is the full name of C plus Plus, CPP can be compatible with C, so you can use CPP to write C program, you can also directly write C;

4. ' In any C program, the. Main function is used as the entry for the program, starting from the main function and ending with the main function. Void is the return value of the function, which is the type of the function's output value. The return value can be an empty type.

5.C language strictly case-sensitive;

6..h is the header file, the head of the abbreviation. The source file for the C language can be. C and. H,cpp source files are CPP and. h;

' 7.//is used to annotate the source code. The compiler will automatically ignore//after the content. Only one line can be commented,/* */May comment on multiple lines;

8. Annotations are helpful for programmers to read and understand the code, and annotations do not increase the size of the post-compilation program or affect the program's operation.

9. Errors in computer programs, defects, vulnerability--dug, the process of eliminating errors becomes--debug.

10. Breakpoints are a debugging method that is specially set up to facilitate the programmer to observe the internal state of the program during the debugging process. When the program runs to a breakpoint, it will be automatically paused, but the program's memory, registers and other data will be retained for the programmer to view;

The 11.C language itself does not provide input and output statements, and relies on the standard library for input and output.
