Introduction
Arithmetic operators are fundamental in any programming language, and C is no exception. These operators perform various mathematical operations, from basic addition and subtraction to more complex operations like modulus and exponentiation. The operators include addition (+), subtraction (-), multiplication (*), division (/), and modulo (%).
What are arithmetic operators in C?
Arithmetic operators are symbols used to perform mathematical calculations. The main arithmetic operators in C are addition +, subtraction -, multiplication *, division /, and modulus %.
Example
C
C
#include <stdio.h> int main() { int a = 10, b = 5; printf("Addition: %d\n", a + b); printf("Subtraction: %d\n", a - b); printf("Multiplication: %d\n", a * b); printf("Division: %d\n", a / b); printf("Modulus: %d\n", a % b);
Name the list of arithmetic operators in C language?
( + ) Addition Operator.
( – ) Subtraction Operator.
( * ) Multiplication Operator.
( / ) Division Operator.
( % ) Modulo Operator.
( ++ ) Increment Operator.
( — ) Decrement Operator.
( + ) Unary Plus Operator.
What is the use of the modulus operator in C?
In C's arithmetic operators, the modulus operator calculates the remainder of integer division between two operands. It divides the numerator by the denominator to determine the result, effectively producing the remainder.
How does the division operator work with different operand types?
If both operands are integers, the result of the division operation will be an integer. If one or both operands are floating points, the result will be a floating-point number.
What are arithmetic logical and relational operators in C?
In C programming language, arithmetic operators perform mathematical operations (+, -, *, /, %). Logical operators work with boolean values (&&, ||, !) for logical expressions. Relational operators compare values (==, !=, <, >, <=, >=).
What is the difference between increment/decrement operators and addition/subtraction?
The Increment Operator adds 1 to the operand, while the Decrement Operator subtracts 1 from the operand. The Postfix decrement operator involves evaluating the expression with the variable's initial value before decreasing the variable itself.
Why is it called arithmetic?
Arithmetic, derived from the Greek word arithmos (meaning "number"), focuses on basic mathematical operations: addition, subtraction, multiplication, and division. It's foundational for numerical calculations and forms the basis for advanced mathematical concepts and problem-solving.
Conclusion
Arithmetic operators in C allow programmers to perform a variety of mathematical calculations, making them an indispensable part of the language. Understanding these operators and their specific behaviors is vital for writing efficient and effective C code.
