if (pinFiveInput < 500) { // 执行A操作 } else { // 执行B操作 } else可以进行额外的if检测,所以多个互斥的条件可以同时进行检测。 测试将一个一个进行下去,直到某个测试结果为真,此时该测试相关的执行语句块将被运行,然后程序就跳过剩下的检测,直接执行到if/else的下一条语句。当所有检测都为假时,若...
这是因为 C 语言按以下规则进行运算 if (x=10):10 赋值给 x(只要非 0 的数赋值的 语句,其赋值 表达式的值永远为真),因此 x 现在值为 10。此时 if 的测试表达式值为 10, 该值永远为真,因为非 0 值永远为真。所以,if(x=10) 将永远为真,这就不是我们运行 if 所期待的结果。另外,x 被赋值为 10...
