Chapter 5.7, Problem 5.7CP

A)

Explanation of Solution

Analysis of given code:

The given code is used to print “Hello world” once. The process is carried out using a “do…while” loop. Initially the “count” variable is assigned with a value “3”. The loop executes till the value of “count” is lesser than “1”.

Given code segment:

//Include necessary header file

#include <iostream>

using namespace std;

//Function main

int main()

{

    // Declare and initialize a variable

    int count = 3; //Line 1

    //Loop

    do //Line 2

    { //Line 3

        // Print statement

        cout<<"Hello World...

B)

Explanation of Solution

Analysis of given code:

The given code is used to print value of the variable “val”. The process is carried out using a “do…while” loop. Initially the “val” variable is assigned with a value “5”. The loop executes till the value of “val” is greater than or equal to “5”.

Given code segment:

// Include necessary header file

#include <iostream>

using namespace std;

// Driver function main()

int main()

{

    // Declare and initialize variable

    int val = 5; //Line 1

    //Loop

    do //Line 2

&...

C)

Explanation of Solution

Analysis of given code:

The given code is used to print the value of variables “number” and “count” on the screen. The “do…while” loop is used to increment the value of variable “number” by “2” add the value of variable “count” by “1”.

Given code segment:

// Include necessary header file

#include <iostream>

using namespace std;

// Function main

int main()

{

    // Declare and initialize variables

    int count = 0, number = 0, limit = 4; //Line 1

    //Loop

    do //Line 2

    { //Line 3

        // Increment number by 2

        number+=2; //Line 4

        // Increament count by 1

        count++; //Line 5

    } //Line 6

    //Condition

    while(count < limit); //Line 7

    //Display number and count

    cout << number << " " << count <<endl; //Line 8

    //Return value

    return 0;

}

Explanation:

• In “Line 1”, declare the variables “count”, “number”, and “limit” and initialize it to “0”, “0”, and “4” respectively...
