Exception Handling in C

Unlike languages like C++ and Java, C does not have built-in exception handling.

In this lesson, you will learn:

• How to handle errors using return values.
• How to use setjmp and longjmp for exception handling.
• How to use errno for system error handling.

Handling Errors with Return Values

The simplest way to handle errors in C is to use return values.

Example:

int divide(int a, int b) { if (b == 0) return -1; // Error code return a / b; }

The caller checks the return value for errors.
