initialisation of members of structures in a dynamic array ??
[/b]

#include <iostream>
using namespace std;
struct exam
{
	char name[15];
	int roll;
	double grade;
};

int main()
{
	
	exam * p = new  exam[3];
	
        \\ how should i initialise the structure members??
	
	

	
	
	cin.get();
}

C++ string literals are arrays of const char, so you can't legally modify them.
Change name to be a const char pointer and it should work.

Well if you don't want to change the type of "name" then you should initialise it as you would an array for characters... i think the way you intialised the other members were fine

Edit:
you can use brace syntax to intialise the name only in C++0x. Otherwise you will have to use a for loop to assign each letter manually

how should i initialise the structure members??

std::strcpy(p[0].name, "mjatt");
p[0].roll = 5;
p[0].grade = 2.7;
std::strcpy(p[1].name, "Void life");
p[1].roll = 8;
...

thanks @ Peter87

By the way , what is wrong with this;

p[0].name = "mjatt";

The problem is that you can't assign arrays like that. That's one of the reasons why we often prefer to use std::string instead of raw arrays to store text. If you change the type of exam::name to std::string you will be able to to do it exactly as you wrote it.
