A counter is a sequential circuit that stores the number of times a particular event has occurred in form of a clock pulse. Counters can be designed by connecting individual flip-flops together. Counters are used in digital electronics for the purpose of counting. When the clock pulses are applied to a counter, it progresses from […]

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
