While loop: It allows users to execute a block of code if a specific condition is true. Do-while loop: This allows users to execute a block of code at least once and then repeatedly execute it if a specific con
The for loop in C first evaluates the initialization expression. If it evaluates true, the first iteration of the loop will run, if false the loop will not run. The code within the loop will executed and then the loop will be updated by the loop expression and re-evaluated. If it is ...

名字绑定的作用域是一个块,这样的作用域就是块作用域。它几乎存在于所有的块结构化编程语言中,例如 C 系语言。大多数情况下块一般都在函数内。 块作用域一般用于控制流,比如 if,while 和 for 循环。但是拥有块作用域的语言一般都会允许使用“裸露”的块,这样就可以在块中定义辅助变量并使用,在块终结时销毁。

2. When checking IF conditions, and you use multiple IFs, there is a risk of the IFs after the first IF condition never being checked. Use ELSE IFs for VL to check every condition in a Visual Logic Block. 3. First, create the Global/Local Data items, Distributions or Labels as discuss...
