C is one of the most widely used general-purpose programming languages. It is widely used for writing programs in many different domains including operating systems, numerical computing, graphical applications, etc.
C Operators specify what is to be done to objects with specific type. Operators act on expressions to form a new expression.
C is a typed language. That means, each variable is given a specific type which defines what values it can represent, how its data is stored in memory, and what operations can be performed on it.
A variable is a named location in memory. Variables are used to give a value a name so we can refer to it later.
The C language provides three types of decision-making constructs: if-else, the conditional expression ?:, and the switch statement.
Iteration statements create loops in the program. In other words, it repeats the set of statements until the condition for termination is met. Iteration statements in C are for, while and do-while.
break, continue and return are branching statements in C. Each of these statement has their importance while doing programming in C.
A function in C is a module of code that takes parameters in , does some computation, and returns a new piece of information based on the parameter information. Functions present a higher level of abstraction and facilitate a divide-and-conquer strategy for program decomposition.
In C, storage class determines the part of storage to allocate memory for a variable. It also determines the scope of a variable.
The scope of a variable is the part of the program within which the variable can be used. So, the scope describes the visibility of an identifier within the program.
