2.2.5. Control Statements (if, else, while, for, switch)

The keyword is followed by one space, then left parenthesis without space, condition, right parenthesis, space, opening bracket on the same line. else and else if are on the same line with the ending brace and opening brace, separated by a space:

if (condition1) {
    statement1;
} else if (condition2) {
    statement2;
} else {
    statement3;
}

In a switch statement, case is indented one level, and the body of each case is indented by another level. The opening brace is on the same line as switch.

switch (expression) {
    case 0:
        command1;
        break;
    case 1:
        command2;
        break;
    default:
        command3;
}
