Chapter 6, Problem 35RQE

Function:

One of the building blocks of C++ program is functions; it contains a group of statements which are used to perform a specific task and the executable segments in a program.

• The function “main()” is most import function in a program, because the “main()” function is the starting point of the program.
• The main advantage of using function is reusability of code and reduces the size of the program, because a function can be called for multiple numbers of times.

Function definition of a function:

The function definition holds a sequence of statement which builds up the function. Return type, parameter list, function name, and body are the parts of the function definition.

Syntax:

//Function definition

datatype function_name()

{

//Function body

}

Function definition for “timesTen”:

The following function “timesTen()” is used to display the product of the argument value by “10”.

/*Function definition for a function "timesTen()" which returns the argument multiplied with "10"*/

void timesTen(int num_Value)

{

//Displays the argument value multiplied by 10

       cout << << (num_Value * 10) << endl;

}

Algorithm:

Algorithm to define a function to find the product of its argument value is as follows:

• Start the program...
