Would like to ask why I have the statement below global variables each function can't use the size?

CodePudding user response:

This is where the global variables of embarrassment,
You'd better think a unique variable names,
As for the size, already with the jam file, so can go wrong,

CodePudding user response:

To compile the results posted

CodePudding user response:

Const int size=5;
So it is good

CodePudding user response:

Because the size is not constant, cannot use array definition, to add const

CodePudding user response:

So try to change the

 const int size=5; 

CodePudding user response:

Upstairs said to want to use very amount then it is an array by new char [size] this form
