Bitwise Operators in C and C++ Programming Languages Uses of Bitwise Operators and Why to Study Bitwise. Compression: Occasionally, you may want to implement a large number of Boolean variables, without using a lot of space. A 32-bit int can be used to store 32 Boolean variables. Normally, the minimum size for one Boolean variable is one...

Interesting facts about Operator Precedence and Associativity in C Language Operator precedence decides which operator’s operation should be performed first in an expression with more than one operators with different precedence. For example 8+ 2 * 10 is calculated as 8 + (2 * 10) and not as (8 + 2) * 10. Associativity in C is used when two operators...

Operators in C and C++ Operators are the foundation of any programming language. Thus the functionality of C language is incomplete without the use of operators. Operators allow us to perform different kinds of operations on operands. In C, operators in Can be categorized in following categories: Arithmetic Operators (+, -, *, /, %, post-increment,...

Constant in C/C++ Constant is a variables or values in C programming language which cannot be modified once they are defined. They are fixed values in a program. There can be any types of constants like integer, float, octal, hexadecimal, character constants etc. Every constant has some range. The integers that is too big to fit into an int will...

Extern keyword in C / C++ Keyword extern is used for declaring extern variables in c. This modifier is used with all data types like int, float, double, array, pointer, structure, function etc. Facts about extern keyword: 1. It is default storage class of all global variables as well all functions. For example, Analyze following second.c code...

Storage Classes in C A storage class defines the scope or visibility and life-time of variables and or a functions within a C Program. They prefix data type . There four different storage classes in a C program − auto register static extern Auto Storage Class The auto storage class is the default storage class for all local variables. And...

Data Types and Modifiers in C/C++ Data Types They are used to define type of variables and contents used. Data types define the way you use storage in the programs you write. Data types can be built in or abstract. Built in Data Types: These are the data types which are predefined and are wired directly into the compiler. eg: int, char etc. User...

Type casting in C  A type cast is basically a conversion from one type to another. There are two types of type conversion: Implicit Type Conversion Also known as ‘automatic type conversion’ and also called as “Widening”. Done by the compiler on its own, without any external trigger from the user. Generally takes place when in an expression...
