title: while Loops - Detail
The basic syntax of a while loop looks like
while (condition)
loop body
The first statement or the first code block after a while statement is considered its body.
code block¶
Anything in curly braces
{ }.
For more than one statement to execute as part of the while loop, we need curly braces.
// Curly braces are required for multiple loop body statements
while (condition) {
loop body
more loop body
}
Use a code block for your loop body even if it is only a single statement. * It makes the code not only more readable, but less prone to errors when you modify it later.
// NO
while (condition)
statement;
// YES
while (condition) {
statement;
}
