Chapter 5: Tackling Typecasting, Decision Control in C

Decision Control Type Conversion      Type conversion , also known as type coercion , is an automatic process performed by the compiler (or programming language) to convert one data type into another without explicit instructions from the programmer. The purpose of type conversion is to facilitate operations between different data types and ensure compatibility. For Example, Consider the code below:    int num1 = 10 ; float num2 = 3.14 ; float sum = num1 + num2; The code declares three variables: num1 (an integer), num2 (a float), and sum (a float).  The variable num1 is initialized with the value 10 , and num2 is initialized with 3.14 . The expression num1 + num2 performs addition between an integer and a float.  During this operation, the compiler automatically converts the num1 integer value to a float.  This conversion, also known as type coercion, enables us to add different data types together. The result of the addition is 13.14 , which is then stored in th

The first printf statement prints the value of x (5) and then increments it by 1, and the second printf statement prints the incre

Chapter 4: Deep Dive into Operators in C

Operators in C Operators are symbols in C programming that perform various operations on operands (variables, constants, or expressions). They allow you to manipulate and perform calculations on data. Here are some commonly used operators in C: Arithmetic Operators. Assignment Operators. Relational Operators. Logical Operators. Bitwise Operators. Increment and Decrement Operators. Conditional (Ternary) Operator. 1. Arithmetic Operators: Why? Arithmetic operators allow you to perform mathematical calculations, making your programs more dynamic and flexible. When? You can use arithmetic operators when you need to add, subtract, multiply, divide, or find the remainder between two values. How? For example, you can use the addition operator (+) to add two numbers together. Arithmetic Operators Addition (+) : Adds two operands together. Subtraction (-): Subtracts the second operand from the first. Multiplication (*): Multiplies two operands. Division (/): Divides the first operand by th
