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.

  #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(); }
