如何在C中转换为大小写转换

Question

if(a > b)
{printf("%d is greater than %d", a, b);}
else if( a < b )
{printf("%d is greater than %d", b, a);}
else
{printf("%d is equal to %d", a, b);}

如何将if语句转换为C中的切换用例？我正在尝试，但我不知道该问题的答案

Answer 1

switch 语句用于根据一组有限的可能值测试输入表达式。

您正在尝试比较两个变量。这不是的用例switch。

您的if/ else if连锁店很好。

Answer 2

switch ((a < b) - (a > b)) {
case -1:
    printf("%d is greater than %d", a, b);
    break;
case 1:
    printf("%d is greater than %d", b, a);
    break;
default:
    printf("%d is equal to %d", a, b);
}
