Solved bca assignment

C supports a rich set of operators. They are classified into following categories:

1.            Arithmetic operators

2.            Relational operators

3.            Logical operators

4.            Assignment operators

5.            Increment and decrement operators

6.            Conditional operators

7.            Bitwise operators

8.            Special operators(Comma ‘,’ and sizeof() operator)

Ø    Arithmetic operators:  C provides all the basic arithmetic operators which are following:

           

Ø    Relational operators:

C provides all the basic relation operators to compare two or more quantities and depending on their relation taking decision. These operators and their meanings are as below.

Ø    Logical operators:

In addition to the relational operators, C has the following three logical operators. The logical operators && and || are used when we want to test more than one condition and make decision.

Ø    Assignment operators:

Assignment operators are used to assign the result of an expression to a variable.

Ø    Increment and decrement operators(Or Binary Operator):

C provides shortcuts to add or subtract constant 1 to a variable.

Ø    Conditional operators:

The conditional operator (ternary operator) pair “?:” is available in C to construct conditional expressions of the form

            Expr1?expr2:expr3

For example

a=100;

b=200;

c=(a>b)?a:b;

Result: c=200

This is same as if..else statement as follows:

if (a>b)

            c=a;

else

            c=b;

Ø    Bitwise operators:

The bitwise operators operate on integers thought of as binary numbers or strings of bits. These operators let us work with the individual bits of a variable; one common use is to treat an integer as a set of single-bit flags.

Ø    Special operators:

C supports some special operators like ‘,’ and sizeof() operators.

The ‘,’ (comma) operator can be used to link the related expression together.

The sizeof() is a compile time operator and, when used with an operand it returns the numbers of bytes the operand occupies. The operand may be variable, a constant or a data type qualifier.
