Introduction to C++

if...elseif...else

The if...else construct in programming allows your program to take different paths and manage various potential outcomes.

It consists of two essential components: a condition and the corresponding actions or consequences based on that condition.

Here's an illustration:

cpp

main.cpp

Here, we use the 2-lines comment.

There is also a handling of the "opposite" case using else:

cpp

main.cpp

There can be other if...else inside the if...else:

cpp

main.cpp

You can also use the else if construct:

cpp

main.cpp
