1. Can local variables have the same name as global variables?

Answer: Yes, the local area will block the global situation.

To use a global variable, you need to use ": : "; a local variable can have the same name as a global variable. When this variable is referenced within a function, the local variable with the same name will be used instead of the global variable.

For some compilers, multiple local variables with the same name can be defined in the same function, such as the

The arm is moved with tears, the letter is rammed, the letter is dug, the copy is extinguished, the copy is extinguished, the haircut is hurriedly driven away, and the macro ants fall back. I have obtained the soup-throwing technique from the Russian mines in winter. Answer: Yes, the local part will block the overall situation.

To use a global variable, you need to use "::"; a local variable can have the same name as a global variable. When this variable is referenced within a function, the local variable with the same name will be used instead of the global variable.

For some compilers, multiple local variables with the same name can be defined in the same function. For example, a local variable with the same name is defined in two loop bodies, and the scope of that local variable is within that loop body.

I win the Russian mining expert's soup-throwing technique. Answer: extern can be used to quote the header file, or extern can be used. Key

word, if you use the header file method to reference a global variable declared in the header file, if you write it incorrectly, an error will be reported during compilation. If you use the extern method to reference it, you will make the same mistake.

error, then no error will be reported during compilation, but an error will be reported during connection.

Answer: Yes, the same name can be declared in different C files in static form.

Global variables.

Global variables with the same name can be declared in different C files, provided that only one C file can assign an initial value to this variable. In this case, the connection will not go wrong. 1. Can local variables have the same name as global variables?
