Nested If-Else Conditions

Pretty often the program logic requires the use of if or if-else statements, which are contained one inside another. They are called nested if or if-else statements. As implied by the title "nested", these are if or if-else statements that are placed inside other if or else statements.

if (condition1)
{
    if (condition2)
    {
        // body; 
    }
    else
    {
        // body;
    }
}

Deep Nesting

Nesting of more than three conditional statements inside each other is not considered a good practice and has to be avoided, mostly through optimization of the structure/the algorithm of the code and/or by using another type of conditional statement, which we are going to examine below in this chapter.
