Function is line 15 and line 32, please? I have noted, bosses analyse, thank you!

CodePudding user response:

Line 15 is a function declaration, if not this line you call this function before 32 rows, it is can't find this function, complains, this line is tells the compiler I have this function, the function just write back,
32 lines to void print (struct student stud) in front of the line is a function prototype function (that is, you say)

This is a function of structure defined?

Is a return value type is the function of structure type

CodePudding user response:

Here you struct student and student are equivalent, MAX is a parameter for the student one dimensional array, the return value is a function of a student structure

CodePudding user response:

Should return pointer, don't write

CodePudding user response:

The difference between the function declarations and function call: pay attention to the different function parameters, function parameters with the data type of the
Is a function declaration (or function definition, function statements with a semicolon at the end of) , with no type is a function call ~

CodePudding user response:

Into a struct student * Max (... )
Returns the return & amp; S [m];
