Return Without Argument Function in C

In C programming, a function that does not take any arguments but returns a value is called a non-void function. The syntax for defining a non-void function is as follows

        Syntax :
           return_type function_name ( ) // Function Definition
           {
                 // body of Statement ;
                  return value;
           }

Here, the return_type specifies the data type of the value that the function will return. The function_name is the name of the function and the value is the value that the function returns.
A non-void function can be called in the same way as other functions, by simply using the function name followed by empty parentheses:

result = function_name();

The value returned by the function is stored in the variable result.
