Difference Between C And C++.

 

  1. C is not an object oriented language (C is a procedural programming language), while C++ is an object oriented language.

  2. In C we use scanf () as standard input function, while in c++ we use cin>> for input. like this for output in c we use printf() while in c++ we use cout<< as a output function.

  3. C does not have the concept of classes and object.

  4. C does not have namespaces while C++ have.

  5. Function overloading is not supported by C. C++ supports function overloading.

  6. C does not have reference variables while C++ uses reference variables.

  7. C++ supports operators overloading, C does not support.

  8. C have top down approach while C++ have bottom up approach.

  9. Data is not structured in C while data is structured in C++.

  10. In C  #include<stdio.h> is used as header file, but in C++  #include<iostream.h> is used as header file.

  11. C does not support C++ programs but C++ support the C program.

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
