   1:  #include<stdio.h>
   2:  #include<conio.h>
   3:  int binary (int);
   4:  void main()
   5:  {
   6:  int num;
   7:  clrscr();
   8:  printf(“\nEnter The Number: “);
   9:  scanf(“%d”,&num);
  10:  binary(num);
  11:  printf(“\n\n\n\n\nPress any key to exit…..”);
  12:  getch();
  13:  }
  14:  //function to convert deciaml to binary
  15:  int binary (int n)
  16:  {
  17:  int r;
  18:  r=n%2;
  19:  n=n/2;
  20:  if (n==0)
  21:  {
  22:  printf(“\nThe binary equivalent is %d”,r);
  23:  return(r);
  24:  }

WAP to calculate the monthly telephone bills as per the following rule: Minimum Rs. 200 for upto 100 calls. Plus Rs. 0.60 per call for next 50 calls. Plus Rs. 0.50 per call for next 50 calls. Plus Rs. 0.40 per call for any call beyond 200 calls.

  #include<iostream.h> #include<conio.h> void main() { int calls; float bill; cout<<" Enter number of calls : "; cin>>calls; if (calls<=100) bill=200; else if (calls>100 && calls<=150) { calls=calls-100; bill=200+(0.60*calls); } else if (calls>150 && calls<=200) { calls=calls-150; bill=200+(0.60*50)+(0.50*calls); } else { calls=calls-200; bill=200+(0.60*50)+(0.50*50)+(0.40*calls); } cout<<" Your bill is Rs. "<<bill; getch(); }   Output: Enter number of calls : 190 Your bill is Rs.250

Write a program to calculate the total expenses. Quantity and price per item are input by the user and discount of 10% is offered if the expense is more than 7000.

  #include<iostream.h> #include<conio.h> void main() { int totalexp, qty, price, discount; cout<<" Enter quantity: "; cin>>qty; cout<<" Enter price: "; cin>>price; totalexp=qty*price; if (totalexp>7000) { discount=(totalexp*0.1); totalexp=totalexp-discount; } cout<<" Total Expense is Rs. "<<totalexp; getch(); }
