Uses of Bitwise Operators Bitwise operators (AND, OR, XOR, NOT, Left Shift, Right Shift) are widely used in various areas of computer science and programming. Here are their practical uses: 1. Bitwise AND (&) Bitwise AND is a simple operation used in computers to compare binary numbers bit by bit. Let’s break it down in […]
Header files in C are files with a .h extension that contain function declarations, macros, and constants. These files are included in a program using the #include directive to access pre-defined functions and symbols. Purpose of Header Files: Provide reusable code for common operations. Enable modular programming by separating declarations and definitions. Reduce redundancy and
Expression in C An expression in C is a combination of variables, constants, operators, and functions that are evaluated to produce a result. Types of Expressions: Arithmetic Expressions: Use arithmetic operators (+, -, *, /, %). Example: a + b – c. Relational Expressions: Compare values using relational operators (<, >, <=, >=, ==, !=).

An operator is a symbol that performs a specific operation on one or more operands (variables or values). Operators are used to manipulate data and variables in a program. Classification of Operators Operators in C are classified into the following categories: 1. Arithmetic Operators Perform basic arithmetic operations. Operator Description Example + Addition a +
Source Code: Human-readable code written in a programming language like C, Python, or Java. Assembly Code: Low-level code with readable instructions (mnemonics) specific to a machine’s architecture. Object Code: Partially translated binary code, generated by a compiler or assembler, not directly executable. Machine Code: Binary code (0s and 1s) directly understood and executed by the
