Nesting Loops

Summary

In this lab, you add nested loops to a C++ program provided. The program should print the outline of the letter E. The letter E is printed using asterisks, three across and five down. This program uses cout << "*";to print an asterisk and cout << " "; to print a space.

Instructions

Write the nested loops to control the number of rows and the number of columns that make up the letter E.

In the loop body, use a nested if statement to decide when to print an asterisk and when to print a space. The output statements have been written, but you must decide when and where to use them.

Execute the program by clicking the Run button at the bottom of the screen. Observe your output.

Modify the program to change the number of rows from five to seven and the number of columns from three to five. What does the letter E look like now?

// LetterE.cpp - This program prints the letter E with 3 asterisks

// across and 5 asterisks down.

// Input: None

// Output: Prints the outline of the letter E.

#include

using namespace std;

int main()

{

const int NUM_ACROSS = 3; // Number of asterisks to print across

const int NUM_DOWN = 5; // Number of asterisks to print down

int row; // Loop control for row number

int column; // Loop control for column number

// This is the work done in the detailLoop() function

// Write a loop to control the number of rows.

// Write a loop to control the number of columns

// Decide when to print an asterisk in every column.

cout << "*";

// Decide when to print asterisk in column 1.

cout << "*";

// Decide when to print a space instead of an asterisk.

cout << " ";

// Figure out where to place this statement that prints a newline.

cout << endl;

}

// This is the work done in the endOfJob() function

return 0;

} // End of main()
