我正在尝试编写一种方法，该方法通过传递char指针来更改
Out1和
Out0的原始值，并提供按位比较功能。主文件测试各种值。但是，即使我强制转换，我仍会收到错误消息，说
Out1的
Out0和
fsm构成
pointers from integers without a cast。任何帮助将不胜感激。这是代码。
#include <stdio.h>
#include <stdlib.h>
void fsm(char I1, char I0, char Reset, char *Out1, char *Out0){
int I1num = I1-'0';
int I0num = I0-'0';
int ResetNum = Reset - '0';
int Out1Num = *Out1 - '0';
int Out0Num = *Out0 - '0';
int Out1Final = (Out0Num & !I0num & Out1Num)|(!Out0Num & I0num)|(!Out0Num & !Out1Num)|(I0num & !Out1Num);
int Out0Final = ((!(Out1Num & I0num) & !(!Out1Num & I0) & !(Out1Num & !(I0))) & !Out0Num) | (!(!((!Out1Num)&(I1num))&!((Out1Num)&(!I0num)))&Out0Num);
Out1 = (char)(Out1Final);
Out0 = (char)(Out0Final);
