If Else

Single-Branch

// Statements that execute before the branches

if (expression) {
   // Statements to execute when the expression is true (first branch)
} else {
   // Statements to execute when the expression is false (second branch)
}

// Statements that execute after the branches

Multi-Branch

The more branches you add to an If-Statement the more it becomes advantageous to just use a case statement^[C++ Case Statements (Private)]

if (expr1) {
	
} else if (expr2) {
	
} else if (exprN) {
	
} else {

}

Short Circuit Evaluation

A logical operator evaluates operands from left to right. Short circuit evaluation skips evaluating later operands if the result of the logical operator can already be determined.

Operator	Example	Short Circuit Evaluation
operand1 && operand2	true && operand2	If the first operand evaluates to true, operand2 is evaluated.
operand1 && operand2	false && operand2	If the first operand evaluates to false, the result of the AND operation is always false, so operand2 is not evaluated.
operand1 || operand2	true || operand2	If the first operand evaluates to true, the result of the OR operation is always true, so operand2 is not evaluated.
operand1 || operand2	false ||operand2	If the first operand evaluates to false, operand2 is evaluated.
