Concept explainers
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...
