Arithmetic Operators

What is Arithmetic Operators

Arithmetic operators can be used to perform arithmetic operations such as Addition, Subtraction, Multiplication and Division. Arithmetic operators are most commonly used operators in computer programming languages. The operands involved in arithmetic operations must represent numerical value. Thus, the operands can be an integer type, floating point types, double and char(In C, characters represent numerical value according to ASCII table). Arithmetic operators can be divided into  3  types, they are

• Unary Operator
• Binary Operator
• Ternary Operator

Classifications of Arithmetic Operators

Binary Operator in C

Binary operators are act upon a two operands to produce a new value.

Binary Operators - C Program

In this program, we make use of several Binary Operators.

• + is a binary operator, which is used to sum two operands to yield a resultant value.
• - is a binary operator, which is used to subtract two operands to yield a resultant value.
• * is a binary operator, which is used to multiply two operands to yield a resultant value.
• / is a binary operator, which is used to divide two operands to yield a resultant value.
• % is a binary operator, which is used to find the remainder of two operands when divided.

#include <stdio.h> //header file section
int main() //main section
{
int a = 5;
int b = 2;
int l = a + b;
int m = a - b;
int n = a * b;
int o = a / b;
int p = a % b;
printf("Addition of a and b = %d ", l);
printf("\nSubtraction of a and b = %d ", m);
printf("\nMultiplication of a and b = %d ", n);
printf("\nDivision of a and b = %d ", o);
printf("\nRemainder of a and b = %d ", p);
return 0;
}

Unary Operators in C

Unary operators are act upon a single operand to produce a new value.

Unary operator - C Program

Let we make use of minus Unary operator and have fun

#include <stdio.h> //header file section
int main() //main section
{
int x = -5;
int y = -x;
printf("The value of x = %d \nThe value of y = %d ",x, y);
return 0;
}

Increment Operator - C Program

Let we make use of Increment Unary operator and have fun

#include <stdio.h> //header file section
int main() //main section
{
int a = 2;
printf("The value of a = %d ", a);
a = ++a;
printf("\nThe value of a = %d ", a);
return 0;
}

Purpose of increment operator

The vital purpose of increment Unary Operator is to add one to their operand.

Decrement Operator - C Program

Let we make use of Decrement Unary operator and have fun

#include <stdio.h> //header file section
int main() //main section
{
int a = 2;
printf("The value of a = %d ",a);
a = --a;
printf("\nThe value of a = %d ",a);
return 0;
}

Purpose of Decrement operator

The vital purpose of Decrement Unary operator is to reduce or subtract one to their operand.

Address Operator(&) - C Program

Let we make use of Address(&) Unary operator and have fun

#include <stdio.h> //header file section
int main()
{
int n = 10;
printf("The value of n = %d ",n);
printf("\nAddress of n = %u ",&n);
return 0;
}

Where address operator get used

While the programmer plays with pointer, the address operator is the one which is most frequenty get used.

sizeof() Operator - C Program

Let we make use of sizeof() Unary operator and have fun

#include <stdio.h>
int main()
{
int x = 5;
float y = 10;
printf("sizeof (x) = %d \nsizeof (y) = %d ",sizeof(x), sizeof(y));
return 0;
}

Where sizeof() operator get used

While the programmer plays with dynamic memory allocation, the sizeof() operator is the one which is most frequenty get used.
