What are arrays in C?
An array is a collection of data items, all of the same type, accessed using a common name. A one-dimensional array is like a list; A two dimensional array is like a table; The C language places no limits on the number of dimensions in an array, though specific implementations may.

Is operator an example?
1. In computer programming and at the command line, an operator is an object that is capable of manipulating a value or operator. For example, in “1 + 2”, the “1” and “2” are the operands and the plus symbol is the operator.
What is the difference between and operator?
Note The key difference in the working of the two operators and the nature are same. The bitwise OR operator sets the bit value whereas the logical OR operator sets true or 1 if either one of the conditions/bit value is 1 else it sets false or 0.
What is #include in C?
The #include directive tells the C preprocessor to include the contents of the file specified in the input stream to the compiler and then continue with the rest of the original file. … A header file may contain any valid C program fragment.
What is & operator in C?
An operator is a symbol that tells the compiler to perform specific mathematical or logical functions. C language is rich in built-in operators and provides the following types of operators − Arithmetic Operators. Relational Operators.
What is C language simple definition?

What is C operators?
The symbols which are used to perform logical and mathematical operations in a C program are called C operators. These C operators join individual constants and variables to form expressions. Operators, functions, constants and variables are combined together to form expressions. Consider the expression A + B * 5.
What is an operator give example?
1. In mathematics and sometimes in computer programming, an operator is a character that represents an action, as for example x is an arithmetic operator that represents multiplication. In computer programs, one of the most familiar sets of operators, the Boolean operators, is used to work with true/false values.

Is a unary operator?
A unary operator is one that takes a single operand/argument and performs an operation. A unary operation is an operation with only one operand. This operand comes either before or after the operator. … Additionally, unary operators can not be overridden, therefore their functionality is guaranteed.
How does & work in C?
The & (bitwise AND) in C or C++ takes two numbers as operands and does AND on every bit of two numbers. The result of AND is 1 only if both bits are 1. … The >> (right shift) in C or C++ takes two numbers, right shifts the bits of the first operand, the second operand decides the number of places to shift.
