The for loop in C language is used to execute a statement or a part of a program multiple times. It is often used to traverse data structures such as arrays and linked lists. The syntax of the for loop in C is as follows: for (Expression 1; Expression 2; Expression 3) { // Code … Read more
Written by Wei Song & Wei Qing Typesetting by Dastin Computers play an irreplaceable role in various fields, including scientific research and finance, and programming ability is an important criterion for many laboratories when selecting students. Even if you may never use C language again, this 4-credit course is still very important as an introductory … Read more
Why Use Structures? In C language, there are situations where multiple attributes of an entity need to be stored. Not every entity has all information of only one type. It can have different attributes of different data types. For example, an entity “student” may have a name (string), roll number (integer), and marks (float). To … Read more
◆Key Point 1: Method to Swap Two Variable Values 1) Using a third variable (the easiest method) 2) Using addition and subtraction to swap values (commonly used in interviews **) The code is as follows: b = a – b; a = a – b; b = a + b; 3) Using bitwise XOR to … Read more
Loops can be defined as the process of repeatedly executing the same procedure multiple times until a specific condition is met. In C, there are three types of loops. In this part of the tutorial, we will learn about various aspects of C loops. Why Use Loops in C? Loops simplify complex problems into simpler … Read more
The most common errors related to pointers and memory management are dangling pointers. Sometimes, programmers fail to initialize pointers with a valid address, and such uninitialized pointers are called dangling pointers in C language. Dangling pointers occur when an object is destroyed, and the pointer’s value is not modified when the object is deleted or … Read more

In C, the boolean type is a data type that contains two values, namely 0 and 1. Essentially, the value of the bool type represents two behaviors, namely true or false. Here, '0' represents the false value, while '1' represents the true value. In C, '0' is stored as 0, while other integers are stored … Read more
All types in C language are as follows: 1. Integer Types (int, short, long, long long) 1.1 Signed Integer The signed integer data types typically include four types: int, short, long, and long long. Since they are signed types, they are prefixed with signed, although this is usually omitted. Therefore, when you write int in … Read more
