Every function declaration and definition must specify a return type, whether or not it actually returns a value. The user-defined type may also be defined within the function declaration.

Can you return a function in C++?

Return Function Pointer From Function: To return a function pointer from a function, the return type of function should be a pointer to another function. But the compiler doesn’t accept such a return type for a function, so we need to define a type that represents that particular function pointer.

What is the return type of function sqrt ()?

The SQRT function returns the square root of a floating-point number; only the built-in types REAL, FLOAT, and DOUBLE PRECISION are supported. The return type for SQRT is the type of the parameter. Note: To execute SQRT on other data types, you must cast them to floating-point types.

How to make a function in C?

A function is a block of code that performs a specific task. C allows you to define functions according to your need. These functions are known as user-defined functions. For example: Suppose, you need to create a circle and color it depending upon the radius and color. You can create two functions to solve this problem: createCircle () function.

How to make a method in C?

Class Methods. Methods are functions that belongs to the class.. There are two ways to define functions that belongs to a class: Inside class definition; Outside class definition; In the following example, we define a function inside the class, and we name it “myMethod”.Note: You access methods just like you access attributes; by creating an object of the class and using the dot syntax (.
