Actually handling exceptions is the job of the catch block (s). The catch keyword is used to define a block of code (called a catch block) that handles exceptions for a single data type. Here’s an example of a catch block that will catch integer exceptions: catch (int x) { // Handle an exception of type int here.In lesson 4.1 -- Introduction to fundamental data types, we introduced the fundamental data types, which are the basic data types that C++ provides as part of the core language.. We’ve made much use of these fundamental types in our programs so far, especially the int data type. And while these fundamental types are extremely useful for …9.6 — Assert and static_assert. Alex December 28, 2023. In a function that takes parameters, the caller may be able to pass in arguments that are syntactically valid but semantically meaningless. For example, in the previous lesson ( 9.4 -- Detecting and handling errors ), we showed the following sample function:if we know the exact number of times to repeat the loop for, we use a "for" loop. The syntax has 4 parts, the initialization, test expression, modifying expression and the code block to be executed in loop. cout << "Hello C++" << endl; } In the above example, we are declaring a loop variable i, which is initialised to 0.Actually handling exceptions is the job of the catch block (s).
