# 【Lua中关系运算符的使用教程】c语言中关系运算符

 这篇文章主要介绍了Lua中关系运算符的使用教程,是Lua学习入门中的基础知识,需要的朋友可以参考下 下表列出了所有的Lua语言支持的关系运算符。假设变量A持有10和变量B持有20则： 示例 试试下面的例子就明白了所有的Lua编程语言提供的关系运算符： 代码如下: a = 21 b = 10 if( a == b ) then print("Line 1 - a is equal to b" ) else print("Line 1 - a is not equal to b" ) end if( a ~= b ) then print("Line 2 - a is not equal to b" ) else print("Line 2 - a is equal to b" ) end if ( a < b ) then print("Line 3 - a is less than b" ) else print("Line 3 - a is not less than b" ) end if ( a > b ) then print("Line 4 - a is greater than b" ) else print("Line 5 - a is not greater than b" ) end -- Lets change value of a and b a = 5 b = 20 if ( a <= b ) then print("Line 5 - a is either less than or equal to b" ) end if ( b >= a ) then print("Line 6 - b is either greater than or equal to b" ) end 当建立并执行上面的程序它会产生以下结果： 代码如下: Line 1 - a is not equal to b Line 2 - a is not equal to b Line 3 - a is not less than b Line 4 - a is greater than b Line 5 - a is either less than or equal to b Line 6 - b is either greater than or equal to b
