Dear, this is the LearingYard Academy!
Today, first introduction to C++ (VI) - The pinnacle，welcome to visit!
一、循環嵌套
1. Loop nesting
循環嵌套，即循環中包含另一層或多層循環，通過兩個或多個循環語句實作多重循環，解決問題。
Loop nesting, that is, the loop contains another layer or multiple layers of loops, through two or more loop statements to achieve multiple loops, to solve the problem.
二、循環嵌套案例——九九乘法表
2. Circular nesting cases - 99 times table
通過兩層循環，依次實作因數相乘，輸出九九乘法表。
Through two layers of loops, multiplication of factors is realized in turn, and multiplication table 99 is output.
三、跳轉語句（一）——break語句
3. Jump statement (1) -- break statement
break語句用于跳出循環或者switch語句，多層循環時隻能跳出該層循環，外層循環繼續執行。
The break statement is used to exit the loop or the switch statement. In a multi-layer loop, only the loop of this layer can be exited, and the outer loop continues to execute.
四、跳轉語句（二）——continue語句
4. Jump statement (2) -- continue statement
continue的作用是立即執行本層循環的下一次循環，continue與break一樣，多層循環時，隻作用于該層循。
The function of continue is to execute the next loop of this layer immediately. continue, like break, applies only to the loop of this layer.
五、跳轉語句（三）——goto語句
5. Jump statement (3) - goto statement
goto語句是無條件無限制跳轉語句，可跳出多層循環，，無邏輯，代碼可讀性差，故一般不用。
goto statement is an unconditional unlimited jump statement, can jump out of multi-layer loops, no logic, code readability is poor, so it is generally not used.
