Operators in C programming

Operators in C What is that? The article will tell you operators in C same way to use them.

In the C language, operators are symbols that represent operations performed on one or more operands. They are the basic components of C programming. In this lesson, let's learn about all the built-in operators in C with specific illustrative examples.

What is the C operator?

Operators in C can be defined as symbols that help us perform some specific mathematical, relational, conditional or logical operations on values ​​and variables. The values ​​and variables used with operators are called operands. So we can say that operators are symbols that perform mathematical operations on operands.

For example: c = a + b;

Here, '+' is the operator called addition operator, and 'a' and 'b' are the operands. The addition operator tells the compiler to add both operands 'a' and 'b'.

Although the + operator is often used to add two values ​​together, as in the example above, it can also be used to combine a variable and a value or two variables. For example:

int sum1 = 100 + 50; // 150 (100 + 50)
int sum2 = sum1 + 250; // 400 (150 + 250)
int sum3 = sum2 + sum2; // 800 (400 + 400)

C divides operators into the following groups:

• Arithmetic operators
• Assignment operator
• Comparison operator
• Logical operators
• Bit comparison operator

C There are a series of operators that let you perform different calculations or equations. Here's what you need to know about implementing operators in the C programming language.

The tutorial will explain arithmetic, relational, logical, bit comparison, assignment, and other operators one by one.

Arithmetic operators in C

The following table shows all the arithmetic operators supported by the C language. Assume variable A has the value 10 and variable B has value 20:

Relational operators

The following table shows all the relational operators supported by the C language. Assume that variable A has the value 10 and variable B has value 20, we have:

Logical operators

The following table shows all the logical operators supported by the C language. Assume variable A has value 1 and variable B has value 0:

Bit comparison operator

The bit comparison operator works on bit units, calculating a bitwise comparison expression. The table below for &, |, and ^ is as follows:

Suppose if A = 60; and B = 13; then now in binary format they will be as follows:

A = 0011 1100

B = 0000 1101

—————–

A&B = 0000 1100

A|B = 0011 1101

A^B = 0011 0001

~A = 1100 0011

The bit comparison operators supported by the C language are listed in the table below. Suppose we have variable A with value 60 and variable B with value 13, we have:

Assignment operator

These are the assignment operators supported by the C language:

Mixed operators ↦ sizeof & ternary

There are some important mixed operators namely sizeof and ? : supported by C language.

Operator precedence order in C

Operator precedence in C determines how expressions are evaluated. For example, the multiplication operator has precedence over the addition operator, and it is performed first.

For example, x = 7 + 3 * 2; Here, x is assigned the value 13, not 20 because the * operator has higher precedence than the + operator, so it first multiplies 3 * 2 and then adds with 7.

The table below lists the order of precedence of the operators. The operators with the highest precedence appear at the top of the table, and the operators with the lowest precedence appear at the bottom of the table. In an expression, the operators with the highest precedence are evaluated first.
