Digital Logic Electronic circuits are divided into two categories, digital and analog. An analog quantity varies continuously and digital quantities only have discrete values. Digital systems can process, store, and transmit data more efficiently. But it can only assign discrete values. Many systems use a mix of analog and digital signals. For example, a CD […]

In this tutorial, you will learn about different operators in C programming. An operator is a symbol that instructs a computer to perform certain operations. Operators are typically used as part of mathematical or logical expressions. C supports a rich set of operators to perform various operations. C Arithmetic Operators An arithmetic operator performs mathematical
A symbolic constant is a name given to any constant. In C, the preprocessor directive #define is used for defining symbolic constants. #define instructions are usually placed at the beginning of the program. By convention, the names of symbolic constants are written in uppercase, but this is not compulsory. The syntax for creating a symbolic

In this tutorial, you will learn primary data types in C programming. Data types are used to determine the size and type of data stored in a variable. For example, Here mark is a variable of type int. That is mark can store integer values. C supports the following classes of data types: Primary data
In this tutorial, you will learn about variables and constants in C. Variables A variable is a data name that can be used to store data. A variable may take different values at different times during the execution of a program. A variable name can be meaningfully chosen by the programmer, subject to the conditions

C is a procedural programming language initially developed by Dennis Ritchie at Bell Laboratories in 1972. It was developed along with the UNIX operating system. The syntax of many programming languages including Java, PHP, JavaScript is primarily based on the C language. Features of C Programming Language The growing popularity of C is most likely
