我有以下法典:
float x = 0.43;
float y = 1.56;
size_t largerValueIndex = 1;
size_t smallerValueIndex = 0;
switch (x > y) {
case 1:
largerValueIndex = 0;
smallerValueIndex = 1;
break;
}
视力演播室发布警告“C4144: > :作为开关声明的关系表述”。
What I d like to know is why is the warning necessary? I was under the impression that most switch and if statements are comparisons between two values. Is this considered bad practice? And if so, why?
我的问题必须涉及作为开关表达方式所使用的价值,而不是那些情况。
虽然switch (-relational expression- ) 是法律,但通常不使用,因为只有两种价值观和if ( expression){......true Code...} 否则{......false Code......>更容易理解。
转换通常用于一种分类变数或表述,以便有效地列出预期值,而不是一个长期链条<代码>,如果......[......]
虽然该守则是正确的,但switch通常用于具有两种以上可能结果的情景;只有两种可能结果的检验标准应为<>if/code>。
编辑们对此提出警告,因为意外使用<代码>switch<>/code>可能显示一种打字或逻辑错误。
