我想简化这段代码并想让它更智能，大约有 80 个单S和多S。我考虑过状态设计模式的使用，但似乎不会更简单。任何人都可以帮助我解决以下问题：
void spy::run(string num, SingleS single, MultipleS multipleS)
{
if(num == "1")
{singleS.runS1}
else if(num == "2")
{singleS.runS2}
else if(num == "3")
{singleS.runS3}
else if(num == "4")
{singleS.runS4}
else if(num == "5")
{singleS.runS5}
else if(num == "6")
{singleS.runS6}
else if(num == "7")
{singleS.runS7}
else if(num == "8")
{singleS.runS8}
else if(num == "9")
{singleS.runS9}
else if(num == "10")
{multipleS.runS10}
else if(num == "11")
{multipleS.runS11}
else if(num == "12")
{multipleS.runS12}
else if(num == "13")
{multipleS.runS13}
}
}
