float y=4.6; y++=y+1 求结果.. 我这样写对么? 为啥报错.?应该怎么改?求指教

源自：4-2 [Linux C语言] 头文件与函数定义分离

#include<stdio.h>

int main()

{

float y= 4.6;

(y++) = (y+1);

printf("y=%f\n",y);

return 0;

}

报错:

root@super-X10DAi:/home/super/workspace/Equation# gcc equation.c

equation.c: In function ‘main’:

equation.c:5:11: error: lvalue required as left operand of assignment

(y++) = (y+1);

求高手指正.....
