The code is giving runtime error, explain please???

 
#include<iostream>
void main()
{
char  *p[3]={"Hi","to all"};
	for(int i=0;i<=2;i++)
		cout<<p[i]<<endl; 
}

You declared an array containing three char*s, but only supplied two strings in your list. This means that the third one will be a null pointer. So when you're doing cout << p[2] << endl;, you're dereferencing a null pointer and thus invoking undefined behavior.

PS: The standard return type for main is int, not void.

Initializing error here, why???

int *p[3]={1,2,3};

Are you just asking questions off of a test or quiz page?

What is p an array of, and what are you trying to use to initialize it?

[sanwall]

I am just practicing array of pointers and could not understand the reason???
