Thread: compile error

can a fucntion return multiple values ? probabily use of structure may help to return more than one values.

i wrote a code, its giving compile error.

Code:

#include<iostream>
using namespace std;
struct test
{
int flag;
int x;
char y;
};

struct func(); // prototype

int main()
{
struct test d  = func();
if (d.flag==1)  { cout<<"char returned"; cout<<d.y;}
else
cout<<d.x;
}


struct func()
{
struct test c;
ch='A';
if(ch<127) // checking whetehr ch is a char
  {
   c.y= ch;
   c.flag=1;
   return c;
  }

else
{
c.x = 100;
c.flag=0;
return c;
}

}

question 1. > why there is error ?

question 2.> how can i fix those error?

> struct func(); // prototype
You want the name of the struct as well
struct test func(); // prototype

Or since this is c++, you can simply do
test func(); // prototype

Don't forget to fix the actual function as well
