A compiler is required to be able to evaluate constant integral expressions because they are necessary for calculating things like array sizes at compile time. However, the standard only says they "can" -- not "must" -- do so.
Usage example
#define TIMER_100_MS (TIMERB_1_S / 10)- What Is A C Operator?

An operator in C can be defined as the symbol that helps us to perform some specific mathematical, relational, bitwise, conditional, or logical computations on values and variables. The values and variables used with operators are called operands. So we can say that the operators are the symbols that perform operations on operands. For example, Her...
C language provides a wide range of operators that can be classified into 6 types based on their functionality: 1. Arithmetic Operators 2. Relational Operators 3. Logical Operators 4. Bitwise Operators 5. Assignment Operators 6. Other Operators
The arithmetic operators are used to perform arithmetic/mathematical operations on operands. There are 9 arithmetic operators in C language:
The relational operators in C are used for the comparison of the two operands. All these operators are binary operators that return true or false values as the result of comparison. These are a total of 6 relational operators in C:
Logical Operators are used to combine two or more conditions/constraints or to complement the evaluation of the original condition in consideration. The result of the operation of a logical operator is a Boolean value either trueor false.
The Bitwise operators are used to perform bit-level operations on the operands. The operators are first converted to bit-level and then the calculation is performed on the operands. Mathematical operations such as addition, subtraction, multiplication, etc. can be performed at the bit level for faster processing. There are 6 bitwise operators in C:
Assignment operators are used to assign value to a variable. The left side operand of the assignment operator is a variable and the right side operand of the assignment operator is a value. The value on the right side must be of the same data type as the variable on the left side otherwise the compiler will raise an error. The assignment operators ...
Apart from the above operators, there are some other operators available in C used to perform some specific tasks. Some of them are discussed here:
Operators can also be classified into three types on the basis of the number of operands they work on: 1. Unary Operators:Operators that work on single operand. 2. Binary Operators:Operators that work on two operands. 3. Ternary Operators:Operators that work on three operands.
In C, it is very common for an expression or statement to have multiple operators and in these expression, there should be a fixed order or priority of operator evaluation to avoid ambiguity. The below table describes the precedence order and associativity of operators in C. The precedence of the operator decreases from top to bottom. To know more ...

Aug 29, 2023 · How to Set Up a Development Environment for C Programming on Your Local Machine. To start writing C programs on your local machine, you will need the following: A C Compiler; An Integrated Development Environment (IDE) C is a compiled programming language, like Go, Java, Swift, and Rust.
Mar 14, 2022 · C compilers are an example. The C compiler has long been considered a fundamental component of software development. As a result of the C compiler standard, developers can compile and run other people's code without worrying that their compilers will not work.
May 11, 2023 · This article explores the concept of compiler passes in the field of software development, focusing on two types: the Single Pass Compiler and the Two-Pass Compiler (Multi-Pass Compiler). It explains their differences, advantages, and use cases, providing insights into the world of compiler design.
