In C programming language, pointer arithmetic is the process of performing arithmetic operations on pointers. Pointer arithmetic is useful for navigating through arrays, manipulating strings, and working with dynamically allocated memory. When performing arithmetic operations on a pointer, the size of the data type that the pointer points to is taken into account. For example, … Read more
In C programming language, a pointer is a variable that stores the memory address of another variable. A pointer is declared using the * operator, and its value is assigned using the address-of operator &. Pointers are useful for working with arrays, strings, and dynamic memory allocation. Here’s an example of how to declare and … Read more
In C programming language, a function prototype is a declaration of a function that tells the compiler about the name of the function, the arguments it takes, and the type of the value it returns (if any). A function prototype is typically placed at the beginning of a program or in a header file to … Read more
In C programming language, a function is a block of code that performs a specific task. Functions provide modularity and reusability to a program by allowing the programmer to break down a complex program into smaller, more manageable pieces. A function in C has the following parts: 1. Function Declaration: A function declaration tells the … Read more
In C programming language, jump statements are used to transfer control from one part of the program to another. There are three types of jump statements in C: break, continue, and goto. 1. break Statement: The break statement is used to terminate the current loop or switch statement. When the break statement is encountered inside … Read more
In C programming language, loops are used to repeat a block of code multiple times based on a condition. There are three types of loops in C: for loop, while loop, and do-while loop. 1. for Loop: The for loop is used to execute a block of code a fixed number of times. The syntax … Read more
In C programming language, decision making statements are used to execute different code blocks based on different conditions. Two commonly used decision making statements in C are the if-else statement and the switch statement. 1. if-else Statement: The if-else statement is used to execute a code block if a condition is true, and another code … Read more
In C programming language, an expression is a combination of values, variables, and operators that can be evaluated to produce a result. Expressions can include arithmetic expressions, relational expressions, logical expressions, and conditional expressions. Arithmetic expressions are used to perform arithmetic operations, such as addition, subtraction, multiplication, and division. For example: int a = 10, … Read more
In C programming language, operators are symbols or keywords that are used to perform operations on variables and values. There are several types of operators in C, which can be broadly categorized as follows: 1. Arithmetic Operators: These operators are used to perform arithmetic operations such as addition, subtraction, multiplication, division, and modulus. The arithmetic … Read more
In C programming language, a constant is a value that cannot be changed during the execution of a program. Constants can be defined using the const keyword, which tells the compiler that the value of the variable cannot be changed. Constants can be defined using any of the basic data types, such as int, char, … Read more
