constructs / if

Edit on Github

  • The if else statement:

LPC’s if statement is identical to that provided by C. Syntax is as follows:

if (expression)
statement;

Alternately:

if (expression) {
statements;
}

Alternately:

if (expression0) {
statements;
} else {
statements1;
}

Alternately:

if (expression0) {
statements0;
} else if (expression1) {
statements1;
}

The number of else clauses is not explicitly limited.


Another favorite programming construct is the ? : operator, which also operates identical to C. The syntax is:

expression0 ? expression1_if_true : expression2_if_false

In some cases, ? : is an shorter way of expression constructs such as:

if (expression0)
var = expression1;
else
var = expression2;

which can be equivalently translated to:

var = expression0 ? expression1 : expression;
