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
Constants are values or variables in a program that cannot be changed, such as: 10, 20, ‘a’, 3.4, “c programming”, etc. There are different types of constants in C programming. The list of constants in C is as follows: Two Ways to Define Constants in C In C programming, there are two ways to define … Read more
In C language, the conditional operator is also known as the ternary operator. The conditional statement is a statement that makes decisions based on the output of an expression. It is represented by two symbols: '?' and ':'. Since the conditional operator operates on three operands, it is also called a ternary operator. The behavior … Read more

C identifiers are used to represent names in C programs, such as variables, functions, arrays, structures, unions, labels, etc. Identifiers can consist of uppercase letters, lowercase letters, underscores, and digits, but the first character must be a letter or an underscore. If an identifier is not used in external linkage, it is called an internal … 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
