For loop: It allows users to execute a block of code a specific number of times. 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 ...
The while loop executes a block of code while a boolean expression evaluates to true. It terminates as soon as the expression evaluates to false. The boolean expression is evaluated before each iteration. Instead of using the 'while' keyword, it uses th
The continue statement is placed within the body of a loop, such as a for loop, while loop, or do-while loop. This can be executed with the help of if-else in C++. When encountered, the continue statement immediately stops the current iteration of the loop. Control then jumps to the ...

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。 块可以用来隐藏名字绑定。如果在块的外面定义了 n,在块的里面也可以定义名叫 n 的变量,它会遮盖外面的 n。但是这样的风格一般被认为是不好的,因...
