What does it mean to 'instantiate' an object?

Explanation:

Instantiate an object means creating an instance of accessing the property of a class we can create instance or object for that class. The property of class means method and variable with the help of instance we can directly access the method and variable.

For example  

class abc // class abc

{

public:

void sum1() // function definition

{

cout<<" hello "; // display hello

}

};

void main() // main method  

{

abc ob; //  creating an instance  

ob.sum1(); // calling a function sum1  

}

Output:

hello

Here we create a instance of class abc i.e ob which can access the method sum1().
