Chapter 7.2, Problem 12STE

Program Plan Intro

Purpose of given code:

The given code is initializes the array “b[]” and passes each value by calling the function “tripler()” using “for” loop.

Given code:

/*Function definition with argument*/

void tripler(int& n)

{

/*Calculation of "n" value*/

n=3*n;

}

/*Declaration and initialization of variable*/

int b[5]={1,2,3,4,5};

//Error

for(int i=1;i<=5;i++)

/*Call the function with argument value*/

tripler(b[i]);

Explanation of given code:

• The code defines the function “tripler()” which takes the address of an argument.
  • The value of passed by argument is multiplied by “3” and stored into the variable “n”.
• The array variable “b[]” was initialized in type of integer.
• Using “for” loop, call the function with each value of array.
