# 2.2、语句 语句主要分为一般语句、条件语句、循环语句、跳跃语句和异常处理语句。 **一般语句**：空语句（null statement）、表达式语句（expression statement）、组合语句（compound statement，block）。 > The simplest statement is the empty statement, also known as a **null statement**. > A **compound statement**, usually referred to as a block, is a sequence of statements and declarations surrounded by a pair of curly braces. **条件语句**：`if`，`switch`。[Reference: runoob-C++条件语句](https://www.runoob.com/cplusplus/cpp-decision.html) **循环语句**：`while`、`for`、`do while`。[Reference: runoob-C++循环语句](https://www.runoob.com/cplusplus/cpp-loops.html) **跳跃语句**：`break`、`continue`、`goto`。 > A **break** statement terminates the nearest enclosing while, do while, for, or switch statement. > A **continue** statement terminates the current iteration of the nearest enclosing loop and immediately begins the next iteration. A continue can appear only inside a for, while, or do while loop, including inside statements or blocks nested inside such loops. > A **goto** statement provides an unconditional jump from the goto to a another statement in the same function. **异常处理语句**：`try catch`、`throw`。[Reference: runoob-C++异常处理语句](https://www.runoob.com/cplusplus/cpp-exceptions-handling.html)
