Welcome to this thrilling session on runtime errors in C++ programming. We're going to delve into runtime errors, understand their types and occurrences, and learn how to handle them. Mastering this will make your C++ code reliable and fail-safe.
Today, we'll dissect runtime errors, categorize them, and learn how to identify and prevent them in C++ programs.
Runtime errors appear during your program's execution and prevent the program from running as expected. Such errors occur when commands, even though syntactically correct, are logically impossible to execute.
Runtime errors occur in various forms, including:
- Null pointer dereferences: Attempting to access a null pointer’s property.
- Division by zero: Attempting to divide a number by zero.
- Accessing uninitialized variables: Using a variable that has not been assigned a value.
Below are examples for each type
In this example, ptr is assigned the value nullptr. Attempting to dereference the null pointer with results in a runtime error since the pointer does not point to a valid memory address.
