Question Description

Nested Loops

Program 1:

The following program generates displays all two-letter .com internet domain names, 13 names per line.

#include <iostream>

using namespace std;

int main()

{

char letter1, letter2;

int count=0;

cout<<"***Two letter domain names**<< endl;

Cout<<"**************<endl;

for(letter1='a'; letter1<='z';letter 1++)

{

for (letter 2'a';letter2<='z';letter2++)

cout <<letter1<<letter2<<".com\t"'count++;

if(count%13==0)

cout<<endl;

}

count<<endl;

}

}

1.Type in the above program, add your name and date, compile and run the program

2.How many times does the outer loop execute?

3.How many times does the inner loops execute?

4.Modify the program to include two-character .com names where the second character can be a letter or a number, as in a2.com

Program 2:

Write a program that graphically depicts an integer’s magnitude by using asterisk, creating a

histogram.

Hint:The inner loop handles the printing of the asterisk and the outer loop handles exciting until zero is entered. Make sure you don’t accept negative numbers.

Sample run: Enter a positive integer (0 to quit): 5

*****

Enter a positive integer (0 to quit): 8

********

Enter a positive integer (0 to quit):-5

Enter a positive integer (0 to quit):-10

Enter a positive integer (0 to quit): 15

***************

Enter a positive integer (0 to quit): 0

Good Bye!

Submit a copy of the program

and sample output for at least 4-5numbers, including

invalid data.
