文章摘要
这篇文章展示了在编程中使用条件语句来判断变量值关系并执行不同操作的过程。代码中通过`if`语句依次判断变量`a`和`b`的相等性、不等性、大小关系等，并根据判断结果打印相应的信息。文章详细说明了变量赋值和条件判断的基本流程，突出了条件判断在程序控制中的核心作用。
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
