Aside from having to strain my eyes to read that, what do you mean? How to make an array of structs?
sory bro i mean ho to pass structure to a function as pointer
Use new to create a pointer to a structure in main
rectinfo * rinfo = new rectinfo;then just pass it in.
/* i wrote this program in c++ but how to initialize the height ,and width. using this code */
#include<iostream.h>
#include<conio.h>
struct rectInfo
{
int hight;
int width;
//int area;
//int parimeter;
void print()
{
cout<<hight<<" "<<width;
}
};
void main(rectInfo *r)
{
struct rectInfo * p=0;
p->hight=6;
p->width=5;
}
You don't have a function anything like the one in your requirement.
Main always returns an int, and certainly does not take your struct as an argument. I said create an instance of your struct in main.
You don't have to use "struct" in the line struct rectinfo *p=0; , it is required in C but not in C++.
Also note that you're trying to write values into a null pointer when you say p->height = 6; etc.
Also, please use code tags [code] //code goes here [/code].
Honestly, I'd say read over whatever resources you have, and start over again with it.
