Question

Difference between calling the function and invoking the function with example

Answer 1

Answer:

Function calling is when you call a function yourself in a programme.

Function invoking is when it gets called automatically.

one example is :

struct s

{

int a,b,s;

s()

a=2;

b=3;

}

void sum()

{

s=a+b;

}

};

void main()

{

struct s obj; //line 1

obj.sum(); // line 2

}

Here, when line 1 is executed, the function(constructor, i.e. s) is invoked.

When line 2 is executed, the function sum is called.
