This article provides a comprehensive overview of preprocessor directives in C programming language along with relevant examples.   C provides many features like structures, unions and pointers. Another unique feature of the C language is the preprocessor. The C preprocessor provides several tools that are not present in other high-level languages.   The programmer can […]

The storage classes in C specify the scope and lifetime of a variable in a C program. The scope (active) specifies in which parts of the program is the variable accessible and the lifetime (alive) specifies how long a variable is available in the memory so that the program will be able to access that […]

In this article we will learn about types of variables in C language. We will start with what is variable and then learn about types of variables like local variables and global variables.   A variable is a memory location inside memory which is referred using a name. The value inside a variable changes throughout […]

This article provides a comprehensive overview of functions in C programming language along with easy to understand example programs.   Until now, in all the C programs that we have written, the program consists of a main function and inside that we are writing the logic of the program. The disadvantage of this method is, […]

In this article we will learn about String Manipulation in C Programming. We will see different examples on manipulating strings.   As we have already seen in the previously, a string is a collection of characters and strings are maintained as character arrays in C programs.   The common operations or manipulations that can be […]

This article provides a comprehensive overview of arrays in C. First we will define what is an array and then see the syntax and example for creating and using arrays.   Arrays   In all the programs we have done until now, to store and operate on values we have used variables. But at a […]

This article provides a comprehensive overview of strings in C programming language along with example programs.   Strings A string is a collection of characters which is treated as a single data item. A group of characters enclosed in double quotes is known as a string constant. Some of the examples of string constants are: […]

This article provides a comprehensive overview of control statements in C programming with their syntax and control flowcharts.   In C, until so far, in all the programs, the control is flowing from one instruction to next instruction. Such flow of control from one instruction to next instruction is known as sequential flow of control. […]

In this article we will understand what is type conversion and casting in C programming language. First we will understand the definition followed by relevant examples of type conversion and casting.   Converting a data type of an expression to another data type is known as type conversion. Here expression refers to either a variable […]

In this article we will learn about expression evaluation in C with examples. First let’s understand what is an expression and how the expressions are evaluated in a C program.   An expression is a sequence of operands and operators that reduces to a single value. For example, the expression, 10+5 reduces to the value […]
