这是可能的的switch
一部分外 switch
语句序列。即使case 常量的内部和外部的switch
含有共同的值,没有冲突出现。
语法:
嵌套switch
语句的语法如下:
switch(ch1)
case 'A'
fprintf('This A is part of outer switch');
switch(ch2)
case 'A'
fprintf('This A is part of inner switch' );
case 'B'
fprintf('This B is part of inner switch' );
end
case 'B'
fprintf('This B is part of outer switch' );
end
例子:
创建一个脚本文件,并键入下面的代码:
a = 100;
b = 200;
switch(a)
case 100
fprintf('This is part of outer switch %d', a );
switch(b)
case 200
fprintf('This is part of inner switch %d', a );
end
end
fprintf('Exact value of a is : %d', a );
fprintf('Exact value of b is : %d', b );
当运行该文件时,它会显示:
This is part of outer switch 100
This is part of inner switch 100
Exact value of a is : 100
Exact value of b is : 200
