Learn C++ Programming Tutorial Lesson 1 - First Program Requirements Before we start programming in C++ we need a compiler. We will be using a command line compiler for this tutorial. I will be using Borland C++ Compiler 5.5 but you can use any other ANSI/ISO compliant compiler such as gcc. Hello World Program Our first C++ program will print the message "Hello World" on the screen. Open a text editor and start by typing the following line: #include<iostream> The above line includes the header file called iostream which will allow us to use the command to print words on the screen. Next you must type: using namespace std; This will let us use…

Q1. What is Polymorphism? Ans: Polymorphism is phenomena by which we can make make a method for reuse. Polymorphism is an object oriented term. Polymorphism may be defined as the ability of related objects to respond to the same message with different, but appropriate actions. In other words, polymorphism means taking more than one form. Polymorphism leads to two important aspects in Object Oriented terminology - First one is function Overloading and second is function Overriding. Overloading is the practice of supplying more than one definition for a given function name in the same scope. The compiler is left to pick the appropriate version of the function or operator b…

There are lots of introductory C books, but this is the first one that has the no-nonsense, practical approach that has made Nutshell Handbooks® famous. C programming is more than just getting the syntax right. Style and debugging also play a tremendous part in creating programs that run well and are easy to maintain. This book teaches you not only the mechanics of programming, but also describes how to create programs that are easy to read, debug, and update. Practical rules are stressed. For example, there are fifteen precedence rules in C (&& comes before || comes before ?. The practical programmer reduces these to two: Multiplication and division come…

Hi All, I am a beginner developer, I have experience in C and C++ so far. I really would like to develop an own application. While I was doing a research I came across a site (http://www.voip-sip-sdk.com/)that deals with development and it also provides numerous sample programs as well. After going over the page I noticed that the sample programs are developed by a software called Ozeki VoIP SIP SDK. I also found that the samples are in C# that I am not familiar with. Could you suggest me any books or tutorials in C#? Should I first try Visual Studio? Hope you can help me out. Thanks.

Hey! I have made this simple calculator in C++. But it has one bug. When we input a valid choice, It still prints invalid choice after printing the output. If we remove the last if statement and invalid choice part the program works fine. Please tell me whats wrong. #include<iostream.h> #include<conio.h> signed long int x, y, choice; int sum () { cout<<"The sum is "<<x+y; } int mul () { cout<<"The product is "<<x*y; } int sub () { if(x>y) cout<<"The subtraction of smaller number from the greater is "<<x-y; if (x<y) cout<<"The subtraction of smaller number from greater number is "<<y-x; } int div () { …

The computer is fool and doesn't know anything before or after 0,1 so we need to compile every program to convert it in machine code.Don't go that much deep you'll understand these things automatically.So for every C program you wrote you need to complie it using a compiler use ant compiler i recommend Code::Blocks compiler best interface..! Ok we start with here..!! every C program has a starting point and end point denoted with {(start) and }(end) and every program has a main function too..! SO we will write a program which will print First C on the screen.. this is a primilary start to get structure of program. Now we will add a function printf which i…

Ok guys i prepared a few C/C++ short questions for interviews. I had these written in a diary so i'll be typing the questions and answers gradually everyday. I hope these questions and answers help you guys. And please note that i used the age old Turbo C++ compiler for my programs because its light weight and i was using an old P4 machine with 640mb ram back then . So all outputs to these programs will be as per TC++ compiler.
