You must code this in c++. I have Included the full question in description.

Question

Write a program that prompts users to enter:

 

o A character to use (any character besides *)

o The width of the display

o The height of the display

 

to produce an E shape. The middle horizontal line must print at line (height+1)/2. Validate user input to only be positive values and height must be at least 5 and width 2. Any invalid input must loop until a valid value is entered.

 

This is an example for width of 10 and height of 9

You must use separate functions to display the vertical and the horizontal lines.  

Answer 1

#include <iostream>

using namespace std;

//function to get the character

char getCharacter() {

char ch;

while (true) {

cout << "Enter a character to use (any character besides *): ";

cin >> ch;

if (ch != '*') {

return ch;

}

cout << "Invalid input. Please enter a character that is not '*'." << endl;

}

}

int getPositiveInteger(const string& prompt, int minValue) {

int value;

while (true) {

cout << prompt;

cin >> value;

if (cin.fail() || value < minValue) {

cin.clear();

cin.ignore(numeric_limits<streamsize>::max(), '\n');

cout << "Invalid input. Please enter a positive integer of at least " << minValue << "." << endl;

} else {

return value;

}

}

}

void displayHorizontalLine(char ch, int width) {

for (int i = 0; i < width; ++i) {

cout << ch;

}

cout << endl;

}

void displayVerticalLine(char ch, int width, int height) {

for (int i = 0; i < height; ++i) {

cout << ch;

for (int j = 1; j < width; ++j) {

cout << ' ';

}

cout << endl;

}

}

void displayEShape(char ch, int width, int height) {

int middleLine = (height + 1) / 2;

displayHorizontalLine(ch, width);

for (int i = 1; i < height; ++i) {

if (i == middleLine - 1) {

displayHorizontalLine(ch, width);

} else {

displayVerticalLine(ch, width, 1);

}

}

displayHorizontalLine(ch, width);

}

int main() {

char ch = getCharacter();

int width = getPositiveInteger("Enter the width of the display (minimum 2): ", 2);

int height = getPositiveInteger("Enter the height of the display (minimum 5): ", 5);

displayEShape(ch, width, height);

return 0;

}
