c语言中字符串名和字符串名()的区别

Question

I have a hard time understanding what is the difference between

 string name;

and

 string name();

Could someone explain me the difference?

Answer 1

Assuming string is a data type you have already declared, string name; declares the variable name of type string .

The declaration string name(); declares the function name that returns a value of type string .

A variable is a place in memory where the program can store some data. A function is a piece of code that can be executed multiple times, when needed; it can receive (zero or more) arguments and it can optionally return one value.

Answer 2

string name; Declare the string data type variable 'name' in a memory where as string name(); shows the function prototype named as 'name' which returns the string value.
