C/C++ supports two types of selection statements: if and switch. In addition, the ? operator is an alternative to if in certain circumstances for flow control.
if
The Syntax of if statement is
if (expression) statement;
else statement; Continue reading
GCD: The greatest common divisor (GCD), which is also known as the greatest common factor (GCF), of two or more integers, is the largest integer that is a common divisor (factor) of all the given integers.
LCM: The least common multiple (LCM), which is also known as the least common denominator (LCD) in fractions, of two or more integers is the smallest integer that is a common multiple (denominator) of all the given integers. Continue reading
C program to check odd or even: In childhood As you have studied in mathematics that in decimal number system even numbers are divisible by 2 while odd are not divisible by 2, we may use modulus operator(%) which returns remainder, For example, 7%2 gives 1 ( remainder when seven is divided by two). Even numbers are of the form 2*X and odd are of the form (2*X+1) where X is is an integer.We will determine whether a number is odd or even by using different methods all are provided with a code in c language.
C program to perform basic arithmetic operations which are an addition, subtraction, multiplication, and division of two numbers. Numbers are assumed to be integers and will be entered by the user.
This c language program performs the basic arithmetic operation of addition on two numbers and then prints the sum on the screen. For example, if the user entered two numbers as 2, 4 then 6 (2 + 4) will be printed on the screen. Continue reading
Let’s talk about integers. Whole numbers less than zero are called negative integers. The integer zero is neither positive nor negative and has no sign. Two integers are opposites if they are each the same distance away from zero but on opposite sides of the number line. Positive integers can be written with or without a sign. Besides that, an integer without any sign is called Unsigned integer.
The int data type is signed and has a minimum range of at least -32767 through 32767 inclusive. The actual values are given in limits.h as INT_MIN and INT_MAX respectively.
An unsigned int has a minimal range of 0 through 65535 inclusive with the actual maximum value being UINT_MAX from that same header file.
Data types in c give you abilities to choose exact data type of variable for your operation. The type of a variable determines how much space it occupies in storage and how the bit pattern stored is interpreted.
Sample C hello world program: A program that displays “Hello World” String on screen.This program I used, printf library function is used to display text on the screen, ‘\n’ places the cursor at the beginning of next line, stdio.h header file contains a declaration of printf function. The code will work on all operating systems may be its Linux, Mac or any other and compilers. Continue reading

Hello, friend’s C or C++ programming become a compulsory subject of every engineering sector and general education also. If you’re willing to spend few money then I’d strongly recommend you following text or eBook 1) Let Us C by Yashwant Kanetkar 2) Object Oriented Programming With C++ By E Balagurusamy.
