C arithmetic operations play a vital role in performing mathematical calculations in C programming. These operations allow you to manipulate numerical data and provide meaningful outputs. In this article, you'll learn about various C arithmetic operators, their precedence, and some usage examples.
Arithmetic operators in C are essential for performing various mathematical operations on operands (data). They are grouped into different categories depending on their usage and functionality. Understanding these categories will help you utilise these operators and ensure correct and efficient calculations.
In C programming, arithmetic operators are symbols used to perform basic mathematical operations on data. They can be divided into basic arithmetic operators and advanced arithmetic operators, such as modulus and increment/decrement operators. Arithmetic operators take two operands and perform an operation on them, producing a single result.
C programming follows a hierarchy of arithmetic operations similar to the conventional order of mathematical operations. This means that some arithmetic operations take precedence over others. The hierarchy is as follows:
The higher the position of an operation in this hierarchy, the greater precedence it has. Arithmetic operators of equal precedence are evaluated from left to right.
C programming supports various arithmetic operations to perform calculations on different types of data. These operations include basic operations (addition, subtraction, multiplication, and division) and advanced operations (modulus, increment, decrement, and pointer arithmetic). Let's look at these types in detail.
In C programming, pointers are variables that hold memory addresses of other variables. Pointer arithmetic operations are a unique feature allowing you to perform calculations directly on memory addresses.
Pointer arithmetic is the process of manipulating pointer values by using arithmetic operators. C programming supports four basic arithmetic operations on pointers: addition, subtraction, increment, and decrement.
Let's look at an example of pointer arithmetic:

#include
int main() {
int array[] = {10, 20, 30, 40, 50};
int *ptr = array;
printf("Starting pointer address: %p\n", ptr);
ptr += 2;
printf("Updated pointer address: %p\n", ptr);
printf("Value at updated pointer address: %d\n", *ptr);
return 0;
}
In the example, we have an array of integers and a pointer pointing to the first element of the array. We perform addition on the pointer, moving it ahead by two positions in the array, effectively changing the memory address it points to.
When multiple arithmetic operators are used in a C expression, their precedence determines the order in which they are evaluated. This is crucial for understanding how an expression's result is computed.
The precedence rules for C arithmetic operators are as follows:
Consider the following example to understand these precedence rules:
#include
int main() {
int a = 10, b = 20, c = 5, result;
result = a + b * c / 2;
printf("Result: %d\n", result);
return 0;
}
In this example, the expression is evaluated as follows:
So, the final result is 60, following the precedence rules mentioned above. Understanding the precedence of C arithmetic operators is essential for accurate and efficient calculations in your programs.
