x > y (x is greater than y) x <= y (x is less than or equal to y) x >= y (x is greater than or equal to y) 警告: 小心偶然地使用单个等号(例如if(x = 10))。单个等号是赋值运算符,这里设置x为10(将值10存入变量x)。改用双等号(例如if (x == 10)),这个是比较运算符,用于测...

Conditional statements check whether a programmer-specified Boolean condition is true or false. They make it possible to test a variable against a value/compare a variable with another variable and make the program act in one way if the condition is met, and another if it isn’t....
