A university has the following rules for a student to qualify for a degree with A as the main subject and B as the subsidiary subject:
- He should get 55% or more in A and 45% or more in B.
- If he gets less than 55% in A he should get 55% or more in B.
However, he should get at least 45% in A.
- If he gets less than 45% in B and 65% or more in A he is allowed to reappear in an examination in B to qualify.
- In all other cases he is declared to have failed.
Write a program to receive marks in A and B and output whether the student has passed, failed or is allowed to reappear in B.

Code for Program to receive marks in 2 subjects and output whether the student has passed, failed or is allowed to reappear in any subject in C Programming

     # include<stdio.h>
     void main()
     {
         int a,b;
         clrscr();

         printf("Enter marks for subject A : ");
         scanf("%d",&a);

         printf("Enter marks for subject B : ");
         scanf("%d",&b);

         if(a>=55 && b>=45)
             printf("Result : PASS");
     //    else if(b>=55 && a>=45)elseif((a<55 && a>=45) && b>=55)
             printf("Result : PASS");

         elseif(b<45 && a>=65)
             printf("You can re-appear for subject B");

         else
             printf("Result : FAIL");
         getch();
     }
