Consolidate Boolean _And_ Expression

You have two immediately nested if statements. Merge both conditional expressions with the Boolean and operator.

        if(cond1) {
                if(cond2) {
                        /* cond1 and cond2 
                        are true */
                        ...
                }
        }

⇓

        if(cond1 && cond2) {
                /* cond1 and cond2 
                are true */
                ...
        }

Motivation

The Boolean expressions of control-flow statements are usually translated by compilers as the composition of the simpler if statements, rather than being evaluated arithmetically. This refactoring allows to recover the original Boolean expressions. Boolean or expressions are translated via and expressions and negation.

Mechanics

Merge both conditional expressions with the Boolean and operator.
