# C Operator

**C Operator: A Comprehensive Guide with Examples
**

**Introduction:
**

**In the realm of the C programming language, operators play a crucial role in manipulating data and performing various operations. Among the plethora of operators available, the C operator stands out as a fundamental building block for performing arithmetic, logical, and assignment operations. In this blog post, we will learn C operators, explore their functionality, and provide illustrative examples to help you grasp their usage and power.
**

**What is Operator?
**

**In the C programming language, an operator is a symbol that represents a specific operation to be performed on one or more operands. Operators are used to manipulate data, perform calculations, compare values, and assign values to variables.
**

**Arithmetic Operators:
**

**Arithmetic operators are used to perform basic mathematical operations. In C, the common arithmetic operators are:
**

**Addition (+): Performs addition of two operands.**

**Subtraction (-): Performs subtraction of one operand from another.**

**Multiplication (*): Performs multiplication of two operands.**

**Division (/): Performs division of one operand by another.**

**Modulus (%): Returns the remainder after division.**

**Example:
**

#include <stdio.h>int main() {Â int num1, num2, sum, difference, product, quotient, remainder;Â printf("Enter two numbers: ");Â scanf("%d %d", &num1, &num2);Â // Arithmetic operationsÂ sum = num1 + num2;Â difference = num1 - num2;Â product = num1 * num2;Â quotient = num1 / num2;Â remainder = num1 % num2;Â // Displaying the resultsÂ printf("Sum: %d\n", sum);Â printf("Difference: %d\n", difference);Â printf("Product: %d\n", product);Â printf("Quotient: %d\n", quotient);Â printf("Remainder: %d\n", remainder);Â return 0;}

**Output;
**

Enter two numbers: 25 7Sum: 32Difference: 18Product: 175Quotient: 3Remainder: 4

**Relational Operators:**

**Relational operators are used to compare values and determine the relationship between them. The common relational operators in C are:
**

**Equal to (==): Checks if two operands are equal.**

**Not equal to (!=): Checks if two operands are not equal.**

**Greater than (>): Checks if the left operand is greater than the right operand.**

**Less than (<): Checks if the left operand is less than the right operand.**

**Greater than or equal to (>=): Checks if the left operand is greater than or equal to the right operand.**

**Less than or equal to (<=): Checks if the left operand is less than or equal to the right operand.**

**Example:
**

#include <stdio.h>int main() {Â int num1, num2;Â printf("Enter two numbers: ");Â scanf("%d %d", &num1, &num2);Â // Relational operations and display the resultsÂ printf("%d > %d is %d\n", num1, num2, num1 > num2);Â printf("%d < %d is %d\n", num1, num2, num1 < num2);Â printf("%d >= %d is %d\n", num1, num2, num1 >= num2);Â printf("%d <= %d is %d\n", num1, num2, num1 <= num2);Â printf("%d == %d is %d\n", num1, num2, num1 == num2);Â printf("%d != %d is %d\n", num1, num2, num1 != num2);Â return 0;}

**Output;
**

Enter two numbers: 10 510 > 5 is 110 < 5 is 010 >= 5 is 110 <= 5 is 010 == 5 is 010 != 5 is 1

**Logical Operators:
**

**Logical operators are used to perform logical operations on boolean values. The common logical operators in C are:
**

**Logical AND (&&): Returns true if both operands are true.**

**Logical OR (||): Returns true if at least one of the operands is true.**

**Logical NOT (!): Reverses the logical state of the operand.**

**Example:
**

#include <stdio.h>int main() {Â int num1, num2;Â printf("Enter two numbers: ");Â scanf("%d %d", &num1, &num2);Â // Logical operations and display the resultsÂ printf("(%d > 0) && (%d > 0) is %d\n", num1, num2, (num1 > 0) && (num2 > 0));Â printf("(%d > 0) || (%d > 0) is %d\n", num1, num2, (num1 > 0) || (num2 > 0));Â printf("!(%d > %d) is %d\n", num1, num2, !(num1 > num2));Â return 0;}

**Output;
**

Enter two numbers: 5 -3(5 > 0) && (-3 > 0) is 0(5 > 0) || (-3 > 0) is 1!(5 > -3) is 0

**Assignment Operators:
**

**Assignment operators are used to assign values to variables. The common assignment operators in C are:
**

**Assignment (=): Assigns the value on the right to the variable on the left.**

**Addition assignment (+=): Adds the value on the right to the variable on the left and assigns the result to the left variable.**

**Subtraction assignment (-=): Subtracts the value on the right from the variable on the left and assigns the result to the left variable.**

**Multiplication assignment (*=): Multiplies the variable on the left by the value on the right and assigns the result to the left variable.**

**Division assignment (/=): Divides the variable on the left by the value on the right and assigns the result to the left variable.**

**Modulus assignment (%=): Calculates the modulus of the variable on the left by the value on the right and assigns the result to the left variable.**

**Example:
**

#include <stdio.h>int main() {Â int num1, num2;Â printf("Enter two numbers: ");Â scanf("%d %d", &num1, &num2);Â Â // Assignment operationsÂ num1 += num2; Â // num1 = num1 + num2Â printf("num1 after addition: %d\n", num1);Â num1 -= num2; Â // num1 = num1 - num2Â printf("num1 after subtraction: %d\n", num1);Â num1 *= num2; Â // num1 = num1 * num2Â printf("num1 after multiplication: %d\n", num1);Â num1 /= num2; Â // num1 = num1 / num2Â printf("num1 after division: %d\n", num1);Â num1 %= num2; Â // num1 = num1 % num2Â printf("num1 after modulus: %d\n", num1);Â return 0;}

**Output;
**

Enter two numbers: 10 3num1 after addition: 13num1 after subtraction: 10num1 after multiplication: 30num1 after division: 10num1 after modulus: 1
