Chapter 3: Operators and Expressions

 In this chapter, we'll delve into the world of operators and expressions in C programming. Operators are symbols that perform various operations on operands, and expressions are combinations of operators, variables, and constants that produce a result. By the end of this chapter, you'll have a solid understanding of arithmetic, relational, logical, and assignment operators, as well as the order of evaluation in expressions.

Example:

#include <stdio.h> int main() { int num1 = 10; int num2 = 5; int result; result = num1 + num2; printf("Sum: %d\n", result); result = num1 * num2; printf("Product: %d\n", result); return 0; }

Explanation:

We declare three variables: num1, num2, and result, all of type int. Using the + operator, we perform addition and store the result in the result variable. Using the * operator, we perform multiplication and update the result variable. Using printf(), we display the values of the variables and the computed results.

To compile and run the program, follow the same steps as in the previous chapters.

In the next chapter, we'll explore control flow statements, which allow us to control the flow of execution in a C program based on conditions.
