CodePudding user response:

After function is written in the main function, must be first life function prototype,

CodePudding user response:

Function declarations to before, and modified as follows, for reference:

 # include 
#include 
# define a 10 
Typedef struct 
{
Int * data; 
Int length; 
Int Maxsize; 
} SqeList; 

Void Insert (SqeList& L);//function declarations in the former 

Int main () 
{
SqeList L; 
Insert (L);//call in the 
return 0; 
} 

Void Insert (SqeList& L) 
{
L.d ata (int *)=https://bbs.csdn.net/topics/malloc (a * sizeof (int)); 
L.l ength=0; 
"Axsize=10; 
}

CodePudding user response:

The function called after the main function of words need to declare, not before
