1. What are Logical Operators? Logical operators are used to evaluate true/false conditions. In C, the main logical operators are: Operator Symbol Description AND && True if both conditions are true OR ` NOT...

1. What is if…else? The if…else statement allows your program to execute certain code only if a condition is true, and optionally another block if the condition is false. Syntax: if (condition) { //...

1. What is a Boolean? A Boolean represents truth values: True → 1 False → 0 Used in conditional statements, loops, and logical operations. Note: C does not have a built-in bool type in...

1. What are Operators in C? Operators are symbols that perform operations on operands (variables or values). C supports many types of operators for arithmetic, comparison, logical, bitwise, assignment, and more. 2. Types of...

1. What is a Constant? A constant is a fixed value that cannot be altered by the program once defined. Useful for values like pi, tax rates, maximum limits, or configuration values. 2. Types...

1. What is Type Conversion? Type conversion is the process of converting a value from one data type to another. C supports two types of conversions: Implicit Conversion (Type Promotion) Explicit Conversion (Type Casting)...

1. What are Extended Data Types? Extended types are variations of basic data types used to store larger ranges of values or specific types of data. They include: long int / long long int...

1. Integer Data Type (int) #include <stdio.h> int main() { int age = 25; int year = 2025; printf(“Age: %d\n”, age); printf(“Year: %d\n”, year); return 0; } Output: Age: 25 Year: 2025 2. Floating-Point...

1. What is sizeof? sizeof is a compile-time operator in C. It returns the size (in bytes) of a data type, variable, array, or structure. Syntax: sizeof(variable_or_data_type) The result is usually of type size_t...

1. Floating-Point Numbers in C float → single-precision decimal numbers (4 bytes) double → double-precision decimal numbers (8 bytes) By default, printing a float/double may show many decimal places. To control precision, we use...
