下面的题搞不懂x的值

Question

我想的结果是6 3*2

#include <stdio.h>

int main()
{
   /*  Write C code in this online editor and run it. */
   float x=1,y;
   y=++x*++x;
   printf("%f",y);
   return 0;
}

这个表达式具体详细怎么一步步赋值的希望有朋友能解释一下

Answer 1

应该是先算两个 ++ 运算；
++x → x = 2
++x → x =3

y=++x*++x = 3*3 = 9
x = 3

int main()
{
   /*  Write C code in this online editor and run it. */
    float x=1,y;
    y=++x * ++x;
    printf("%f",y);
    printf("\n%f",x);
   return 0;
}
