Reasoning Program

                 Reasoning Program

                               I am a beginner of c-language and I have created this reasoning program to generate or using the logic for reasoning related questions. But I think this code can be modified further to make it more useful so please send your suggestions and use it.

Program To Find The Given Letter.
Coding:-

/*Program to find The Required number*/
#include<stdio.h>
#include<conio.h>
void main()
{
int a,b,c,d,e;
clrscr();

printf("\n Choose The Sequence Of Letters");
printf("\n 1. A to Z.");
printf("\n 2. Reverse Order.");
printf("\n\n\t\t\t");
scanf("%d",&a);
printf("\n Enter the number of the letter -   ");
scanf("%d",&b);
printf("\n Direction \n Left End - 1.\n Right End - 2.\n");
scanf("%d",&e);
getch();
clrscr();
/*Logic*/
/*Normal Order*/
if(a==1 && e==1)
c=b;
if(a==1 && e==2)
c=27-b;
printf("\n%d",c);
/*Reverse order*/
if(a==2 && e==1)
c=27-b;
if(a==2 && e==2)
c=b;
/*Output*/
printf("\n  YOURNUMBER  -  %d",b);
printf("\n  Required Number  - %dth",c);
printf("\n The required letter is at %dth number tally your answer.",c);
printf("\n A-1   B-2   C-3  D-4  E-5  F-6  G-7  H-8  I-9  J-10 K-11 L-12 M-13 \n N-14 O-15");
printf("  P-16  Q-17  R-18 S-19 T-20 U-21 V-22 W-23 X-24 Y-25 Z-26");
getch();
}
