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.

Explanation / Answer

#include<stdio.h>

void printColor(char* item) {
   if (strlen(item) != 5)
       printf("INVALID ITEM ");
   else
       switch(item[2]) {
           case'b':
           case'B':
               printf("Blue ");
               break;
           case'r':
           case'R':
               printf("Red ");
               break;
           case'g':
           case'G':
               printf("Green ");
               break;
           case'w':
           case'W':
               printf("White ");
               break;
           default:
               printf("INVALID ITEM ");
       }
}

void main(){
   char str[10];
   while (1) {
       printf("Enter item: ");
       scanf("%s",str);
       printColor(str);
   }
}
