请告诉我如何使这段代码变得更好和更短。我必须经历每一个条件。这是耗时的。我需要这样做，如果变量值是4，它必须直接去4而不是经历每一个if。
if (image4click)
{
a = 1;
}
if (image4click1)
{
a = 2;
}
if (image4click2)
{
a = 3;
}
if (image4click3)
{
a = 4;
}
if (image4click4)
{
a = 5;
}
if (image4click5)
{
a = 6;
}
in this image4click is boolean variable.how to shorten this make it better.
答案 0 :(得分：0)
我不确定您使用的是哪种语言，但在编程中有一种叫做switch-case的东西。
switch
case 1:
do this...
case 2:
do this...
case 3
do this...
end
显然，您必须查看您正在使用的编程语言的语法。希望这有帮助！
