Question

Write a console program: Code the program so that it displays the color of the item whose item number is entered by the user. All the item numbers contain exactly five characters. Allitems are available in four colors: blue, green, red, white. The third character in the item number indicates the item's color, as follows: B or b = Blue G or g = Green R or r = Red W or w = White If the item number does not contain exactly five characters, or the third character is not one of the characters listed above, the program should display an appropriate message on the screen. The program should use a void function to check the item number to determine the color of the item, and the color should be given to the calling function by using a reference variable. Use an array to store the colors and corresponding characters.

Explanation / Answer

Using c++ program code is below regarding colors.

after program execution we are entering either small or big letter i will give corresponding color.

otherwise not matching color message will display.

#include <iostream>

#include <string>

#include <cctype>

using std:: cout;

using std:: cin;

using std:: endl;

//function prototypes

void getItemNumber

void checkItemNumber

int main()

{

//declare variables

string item = " ";

string item = " ";

cout << "Enter your 5-digit item #: ";

cin >> item;

while (item.length() != 5)

{

cout << "Invalid item #. Please enter a 5-digit item # ";

getline(cin, item);

}

if (item.length() == 5)

{

if( 'B' or 'b' == toupper(item[2]))

cout << "entered color is blue" << endl;

else if ('G' or 'g' == toupper(item[2]))

cout << "entered color is green" << endl;

else if ('R' or 'r' == toupper(item[2]))

cout << "entered color is red" << endl;

else if ('W' or 'w' == toupper(item[2]))

cout << "entered color is white" << endl;

}

else cout<< "Invalid name no matching color...";     // if code is not from any of the above.

system("pause");

return 0;

}

output will be

we are enter b or B -->entered color is blue

we are enter g or G -->entered color is green

we are enter r or R -->entered color is red

we are enter w or W -->entered color is white

otherwise Invalid name no matching color... will display.
