What is C Programming Language? C is a general-purpose programming language that is used to develop firmware or applications. C programming provides base for all programming languages. Most of the modern programming…

C is a widely used language because it provides a lot of features. Some of the features are given below: Modularity Portability Extendability Speed Powerful Memory Management Pointers 1. Modularity Modularity is…

It is always useful to know about the different parts of the C program. It will be helpful for understanding the programs in upcoming chapters. Let us learn about the basic program…

The printf() function is used to display output and the scanf() function is used to take input from users. The printf() and scanf() functions are commonly used functions in C Language. These functions are inbuilt library functions in header files…

Comments are the non-executable code used to provide documentation for the C program. Comments provide details about the code so that other users can easily understand the code by reading those comments….

In simple words, variable is a name given to memory box with a name, where we can “store” some value. Its value can be changed depending upon conditions and it can be…

Constant in C means the content whose value does not change at the time of execution of a program. C Constants are also like normal variables. But, the only difference is, their…

C Constants refer to fixed values whose values remain the same during the whole program. Constants can be of any of the basic data types like an integer constant, a floating constant,…

A data type is a classification that specifies which type of value a variable can store. We need to define data types of each variable during variable declaration. Each data types requires…

C decision statements are used to make a decision, based on some conditions. Types of decision-making statements The if-else statementThe else-if ladder statementThe switch case statement If-else Statement The if statement is…

The c switch statement is used to execute the code of multiple conditions. In a switch statement, you can not use operators, you have to compare with a direct value like int…

Like other programming languages, C language also supports the set of operators to perform a different kind of operations on variables.Now, the question arises, What is Operator? Operator An Operator is defined…

Mostly we see that every C program has at least one function such as main(). We can use more than two C Functions in a single C Program.A function is a group…

C Pointers are the variables whose value is the address of another variables.Pointer Syntax : data_type *var_name; Example : int *p; char *p; Here, * is used to denote that the pointer…

C File handling is an important part of a software application. We mostly need to open the file and process the following tasks: Opening a File Reading a File Writing a File…
