2.  If/ Else if / Else  Variable Scope  Nested if/else's  Switch statements  Conditional Operator

3. int result = 0; if (x > 0) { result += x; } else { result -= x; }

4. int result = 0; if ( ) { } else if( ) { } else if … else { } The boolean expressions are evaluated in sequence from top to bottom. The first boolean expression that evaluates to true has its associated expression list executed. Once a single boolean expression is matched, no more are considered.

5.  The scope of a variable is defined as the section of code in which a variable is defined.  Outside of a variable’s score, the variable does not exist.  The start of a ‘local’ variable’s scope is where it is declared:  int x; //x’s scope begins

6. if( boolean expression) { … if(boolean expression) { … } else if(boolean expression) { … } else {... }

7.  The scope a variable defined in the expression list of an if statement is the expression list. int y = 0; if(x > 0) { int x = a * b; y = x - a/b; } Scope of y Scope of x

8. boolean expression ? expression 1 :expression 2 If the initial boolean expression is true, then expression 1 is executed, if the boolean expression is false then expression 2 is executed. int s = (x < 0) ? -1 : x * x; int max = (a > b) ? a : b; int sign = ( number < 0) ? -1 : ((number == 0) ? 0 : 1);
