Constructor's Purpose : To simplify the program and make your program easier for others to understand
what situation Next recommended constructor : When a function in the program needs to be used many times and the code to realize is long , It's recommended to do it in advance
Yes? Constructors : Simply speaking , What do you want to achieve , Just construct what kind of function
such as : I want to add two numbers . The procedure is as follows :
#include<stdio.h>
int ADD (intx,inty)
{ int z=x+y;
return z;
}
int main()
{ int a=10;
int b=20;
int sum =0;
sum=ADD(a,b);
printf("%d\n",sum);
return 0;
| From this program, we can see , I want to add and subtract two numbers , So I'm in main Define a in advance between functions ADD function , Its function is to add two numbers , Then call this function directly in the main program .
