In C language, the if-else statement is used to perform actions based on specific conditions. If the given condition is true, the operation specified in the if code block will be executed. There are several variants of if statements in C language: If statement: Contains only the if part; if the condition is true, the … Read more
When looking at a program with errors, it can be difficult to know how to fix it. Through my studies of C, I have compiled a list of common mistakes made during C programming for reference. 1. Ignoring the case sensitivity of identifiers. main() { int a=5; printf(“%d”,A); } The compiler treats ‘a’ and ‘A’ … Read more
The switch statement in C is an alternative to the if-else-if ladder, allowing us to perform multiple actions based on different possible values of a single variable, known as the switch variable. Here, we can define statements in multiple cases for different values of the same variable. The syntax of the switch statement in C … Read more
What is ASCII? ASCII stands for American Standard Code for Information Interchange. It is a character encoding scheme used for electronic communication. Each character or special character is represented by an ASCII code, and each ASCII code occupies 7 bits in memory. In the C programming language, a character variable does not contain the character … Read more

An expression is a formula in which operands are connected together using operators to compute a value. Operands can be function references, variables, array elements, or constants. Let’s look at an example: a-b; In the above expression, the minus sign (-) is an operator, and a and b are two operands. There are four types … Read more
Dear students, it’s time for you to prepare some content suitable for teaching new freshmen. I have simplified some of the content here, hoping it will be helpful to everyone. Please correct any mistakes. What is C Language? C language is a general-purpose, procedural programming language. It was designed and developed by Dennis Ritchie at … Read more
Overall, it is essential to understand: 1) There are three types of program structures: sequential structure, selection structure (branching structure), and loop structure. 2) Programs should always be read starting from the main() entry point, reading sequentially from the top down (performing loops when encountering loops, making selections when encountering selections). There is only one … Read more
We know that we can create pointers to any data type, such as int, char, and float. We can also create pointers to functions. The code of a function always resides in memory, which means that the function has a certain address. We can obtain the memory address using function pointers. Let’s look at a … Read more
Strings can be defined as one-dimensional character arrays terminated by a null character (‘\0’). Character arrays or strings are used to manipulate text, such as words or sentences. Each character in the array occupies one byte of memory, and the last character must always be 0. The terminating character (‘\0’) is important in strings because … Read more
