For Statement

The f or for statement provides a compact way to iterate over a range of values. Programmers often refer to it as the for loop because it repeatedly loops until a particular condition is satisfied.

...

for(string user in watchers){
   print(user);
}

Switch Statement

The switch statement offers support for executing different operations depending on the value of a variable. The variable can be either a number or a string.

Syntax

The general syntax for this is:

switch(variable) {
    case value1:
		Instruction11;
		...
		Instruction1N;	
	[break;] 
    case value2:
		Instruction21;
		...
		Instruction2N;
	[break;]
	...
	case valueN:
		InstructionM1;
		...
		InstructionMN;
	[break;]
	[default:
		InstructionDef1;
		...
		InstructionDefN;]
}

Example

switch (season) {
    case "Summer":
        print("It's too hot!");
        break;
    case "Winter":
        print("It's too cold!");
        break;
    default:
        print("It's just fine!");
}

Break Statement

The break statement can be used in two situations:

• inside a loop(for, while): when encountering the break, the execution of the loop is terminated and the control is transfered to the statement that follows the loop;
• in switch statements: when a case is followed by a break, it does not execute subsequent cases and control is transfered out of the switch statement.

Example

for (number i = 0; i < 10; i = i + 1) {
   if (i >= 5) {
	  break;
   }
   print(i);
}

Continue Statement

The continue statement is used inside a loop(for, while) causing it to jump to the next iteration, skipping the execution of the rest of the statements inside the loop for the current iteration.

Example

number i = 1;
while (i <= 10) {
	if (i % 3 == 0) {
		i = i + 1;
		continue;
	}
	print(i);
	i = i + 1;
}

While Statement

The while statement offers support for repeated executions. This form evaluates the condition first and then executes the instructions in the body.

Syntax

while(condition) {
    Instruction1;
    ...
    InstructionN;
}

Example

number i = 1;
while(i <= 3) {
    multisel = arrayAddElement(multisel,"value" + i);
    i = i + 1;
}

...

The do-while statement is similar to the while statement, except the condition is evaluated after the execution of the encapsulated block. So,even if the condition is false, the instructions will still be evaluated once.

Syntax

The general syntax is:

do {
    Instruction1;
    ...
    InstructionN;
} while(condition);

Example

number i = 1;
string [] people;
do {
    people += watchers[i];
    i = i + 1;
} while(i < 5);
