Arithmetic Operators in c#
Arithmetic operators in the C# programming language are used to perform basic mathematical operations, including addition, subtraction, multiplication, division, subtraction, increment, and decrement. Popular arithmetic numerical data operators in C# include +, -, *, /, %, ++, –, etc.
List of popular arithmetic operators in the C# programming language.
| Operator | Operator Detail | Arithmetic Example | Arithmetic output |
| + | Addition (use to add 2 different integer variable) | p + q | Add total of p and q variable value |
| – | Subtraction (use to subtract larger number with small number variable) | p – q | Subtract of p and q variable value |
| * | Multiplication (use to multiply two different number variable) | p * q | Multiply of p and q variable value |
| / | Division (use to divide smaller number with larger number variable) | p / q | Division of p divided by q variable value |
| % | Modulus (Remainder) (use to divide larger number with small number variable if remainder produce then it displays) | p % q | Remainder of p divided by q variable value |
| ++ | Increment (use to increment number of variable value) | p ++ or ++ p | Increases p variable value by 1 |
| — | Decrement (use to decrement number of variable value) | p — or — p | Decreases p variable value by 1 |
Examples of popular arithmetic operators in the C# programming language.
using System;
class ArithmeticOperator
{
static void Main()
{
int p = 24;
int q = 7;
Console.WriteLine($”The Addition of p & q – {p + q}”); // Result is – 31
Console.WriteLine($”The Subtraction of p & q – {p – q}”); // Result is – 17
Console.WriteLine($”The Multiplication of p & q – {p * q}”); // Result is – 168
Console.WriteLine($”The Division of p & q – {p / q}”); // Result is – 3 (integer division of both variables)
Console.WriteLine($”The Modulus of p & q – {p % q}”); // Result is – 3
p++; //here it Increment variable value by 1
Console.WriteLine($”After Increment value of p – {p}”); // Result is – 25
q–; // Here it decrements the variable value by 1
Console.WriteLine($”After Decrement of value q – {q}”); // Result is – 6
}
}
Important Notes in C# Programming Language.
Behavior of Division Arithmetic Operators.
Integer division (int p = 11 / 4;) in a C# program displays the truncated decimal part of the variable.
Here, use the double or float data type for proper division operations with decimals.
double output = 11.0 / 4.0; // Output is – 2.75…
Post-increment (a++) vs. pre-increment (++a) operator in a C#.
- Post-increment – In a C# program, the declared program increments the variable value by one using its current value.
- Pre-increment – In a C# program, a program declares a program variable to increment its value before using it.
Increment Operator Example.
using System;
class IncrementOperator
{
static void Main()
{
int p = 9;
Console.WriteLine(p++); // Result is – 9 (then p variable value becomes 10)
Console.WriteLine(++p); // Result is – 11
}
}
Decrement Operator Example.
using System;
class DecreamentOperator
{
static void Main()
{
int p = 9;
Console.WriteLine(p–); // Result is – 9 (then p becomes 8)
Console.WriteLine(–p); // Result is – 7 (p is first decremented to 7)
}
}
Uses of the modulus operator (%) in C#.
In C# programs, the reminder operator is often used to test divisibility or a condition within a variable’s range. If the value is completely divisible by 3, the reminder will not fire and the output will be true; otherwise, the output will be false.
Modulus operator (%) example.
using System;
class Remainder
{
static void Main()
{
Console.WriteLine(11 % 3 == 0); // Result is – False here (11 is not completely divisible by 3)
}
}
