Question

Write a complete console program in c++ that outputs your entire lower-case English alphabets (26 of them) and their respective numbers in reversed order.

Output should be:

a: 26

b: 25

c: 24

...

x:3

y:2

z:1

Answer 1

C++ CODE

#include<iostream>
using namespace std;

int main()
{
   /*THIS CODE CAN BE WRITTEN USING ASCII VALUES*/
   /* ASCII VALUE OF a: 97 and z : 122 */

   char start='a'; // LOOP WILL START FROM
   char end='z'; // LOOP WILL ENDS HERE
   int i; //ITERATE VARIABLE

   // START VARIABLE TYPE CASTED TO INT , WHICH IS 97, AND FOR z : 123
   // SO LOOP WILL ITERATE FROM 97 TO 123

   for (i=(int)start; i<=(int)end; i++)
   {
       // char(i) : CHARACTER VALUE OF INTEGER I, FOR 97 : IT IS "a"
       //FOR CORRESPONDING NUMBER VALUE : int)end-(i-1)
       //FOR START IS "a" : (int)z-(95-1) => 26
       cout<<char(i)<<":"<<(int)end-(i-1)<<endl;
   }
   return 0;

} // MAIN END
