Chapter 2, Problem 21CP

Explanation of Solution

Given: In C++, the code is as follows:

int a=6;

a-= a + 1;

cout << a << endl;

a*= 6;

cout << a << endl;

a /= 2;

cout << a << endl;

To find: In C++, the output of the following code.

int a=6;

a - = a + 1;

cout << a << endl;

a * = 6;

cout << a << endl;

a / = 2;

cout << a << endl;

Solution:

In the given code, it uses the augmented assignment operator such as subtraction, multiplication, and division.

int a=6;

As the given code shows the data type as an integer, where the variable, a, is declared as “a� and initializes its value as 6.

a - = a + 1;

In code, the subtraction operator is used with a, that is, a-...
