Chapter 4, Problem 6.1E

Explanation of Solution

Given code:

//Declare the variables

int x = 1, total;

//Execute "while" loop

while (x <= 10)

{

    //Perform calculation

    total += x;

    //Increment "x" by "1"

    ++x;

}

Error:

In the given code, the variable “total” is not initialized to perform the calculation.

Corrected code:

//Declare and initialize the variable

int x = 1, total=0;

//Execute "while" loop

while (x <= 10)

{

    //Per...

Explanation of Solution

Given code:

//Execute "while" loop

while (x <= 100)

    //Perform calculation

    total += x;

    //Increment "x" by "1"

    ++x;

Error:

In the given code, the body of “while” is not properly enclosed.

Corrected code:

//Execute "while" loop

while (x <= 100)

{

    //Perform calculation

    total += x;

    //Increment "...

Explanation of Solution

Given code:

//Execute "while" loop

while (y > 0)

{a

    //Print the value of "y"

    System.out.println(y);

    //Increment "y" by "1"

    ++y;

Error:

• In the given code, the body of “while” is not properly enclosed.
• The letter “a” given after opening brace “{” is not related to any syntax and it leads to an error.

Corrected code:

//Execute "while" loop

while (y > 0)

{

    //Print the value of "y"

    System.out...
