Decision Making and Branching

An employee can apply for a loan at the beginning of every six months, but he will be sanctioned the amount according to the following company rules:
Rule 1: An employee cannot enjoy more than two loans at any point of time
Rule 2: Maximum permissible total loan is limited and depends upon the category of the employee.
A program to process loan applications and to sanction loan is given.

#include <stdio.h>
#define   MAXLOAN  50000
void main()
   {
       long int loan1, loan2, loan3, sancloan, sum23;
       printf("Enter the values of previous two loans:\n");
       scanf(" %ld %ld", &loan1, &loan2);
       printf("\nEnter the value of new loan:\n");
       scanf(" %ld", &loan3);
       sum23 = loan2 + loan3;
       sancloan = (loan1>0)? 0 : ((sum23>MAXLOAN)?
      MAXLOAN - loan2 : loan3);
       printf("\n\n");
       printf("Previous loans pending:\n%ld %ld\n",loan1,loan2);
       printf("Loan requested  = %ld\n", loan3);
       printf("Loan sanctioned = %ld\n", sancloan);
       getch();
   }
