Thread: How to get result from display function ?

Hi

How to get result from display function ?

Code:

#include <stdio.h> 
struct student
{
    int x;
    int y;
};
 
struct student* display(struct student *point);
 
int main()
{
    struct student mypoint;
	
    mypoint.x = 72;
    mypoint.y = 22;
	
    display(&mypoint);   
     
    return 0;
}
struct student* display(struct student *point) 
{
  printf("\n Displaying information\n");
  printf("\n x: %d", point->x);
  printf("\n y: %d", point->y);
   
  return point;
}

Displaying information


x: 72
y: 22

Function return integer value

Code:

int display (void){
    int returndata;
    
    return returndata
}

Function return char

Code:

char display (void){
    char returndata;
    
    return returndata;
}

What the value this would be return

Code:

struct student*display (void){
     struct student *point;
    
    
return point;
}

What happen when we call to this function. I have read it when function execute it would return only one value. What type of value it would return integer, character, float, string ?
