C language * Xiaobai's adventure

Beginner learning C language, imitating other people's code, you need to type it again to find the problem

When typing the code, pay attention to "nothing wrong", every character should be exactly the same

For exampleThis G should be surrounded by 'single quotes, I was originally "double quotes, there is a problem with the compilation!'''''''''''''''

You need to think more about yourself, come on boy!
