Lua流程控制语句

Lua提供了两种流程判断控制语句,分别为if和if-else这两种.

if语句

if语句语法格式如下:

if(boolean_condition) then
    statements
end

示例:

a = 10

if (a > 12) then
  print("ho")
end

if-else语句

if-else语句语法格式如下所示:

if (boolean_condition) then
  statements
else
  statements
end

示例:

a = 10

if (a > 12) then
  print("ho")
else
  print("ha")
end

if-elseif-else语句语法格式如下所示:

if (boolean_condition) then
  statements
elseif (boolean_condition) then
  statements
else
  statements
end

示例:

a = 10

if (a == 10) then
  print(a)
elseif (a > 10) then
  print(a)
else
  print(a)
end

that's all
