Code points located at U+10000 or higher must be denoted with the \U syntax, whereas lower code points may use \u or \U. The code point is converted into a sequence of code units in the encoding of the destination type on the target system. For example, where the encoding is UTF-8, and UTF-16 for wchar_t:
Pascal has two forms of the while loop, while and repeat. While repeats one statement (unless enclosed in a begin-end block) as long as the condition is true. The repeat statement repetitively executes a block of one or more statements through an until statement and continues repeating unless the condition is false. The main difference between ...
C program source text is free-form code. Semicolons terminate statements, while curly braces are used to group statements into blocks. The C language also exhibits the following characteristics: The language has a small, fixed number of keywords, including a full set of control flow primitives: if/else, for, do/while, while, and switch.
Then the condition is evaluated. If the condition is true the code within the block is executed again. This repeats until the condition becomes false. Do while loops check the condition after the block of code is executed. This control structure can be known as a post-test loop. This means the do-while loop is an exit-condition loop.

The majority of the most popular programming languages use reserved keywords. Early examples include FLOW-MATIC (1953) and COBOL (1959). Since 1970 other examples include Ada, C, C++, Java, and Pascal. The number of reserved words depends on the language: C has about 30 while COBOL has about 400.
