Function without argument, with return value
In this type of function, we perform input and calculations in the function definition (body).
The result is returned using the return keyword. A function can return only one value at a time.
When value is returned using return keyword the control is transferred from the called function to the calling function.
Declaration:
returndatatype functionname();
Definition
returndatattype functionname()
{ //code goes here
return value;
}
Call
Var=Functionname();
Note: If a function is created with return type then it can be called from the RHS of assignment operator or in the expression.
