出现left side of asn-op not an lvalue 该怎么改

lcd.c(50): error C213: left side of asn-op not an lvalue
在程序中指向void KeyDriver()

unsigned char i, j;
static unsigned char pdata backup[4][4] =

1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1
;

for (i=0; i<4; i++)

for (j=0; j<4; j++)

指向这里 if (backup[j]!= KeySta[j])

if (backup[j] != 0)

KeyAction(KeyCodeMap[j]);

backup[j]= KeySta[j] ;

参考技术A backup[j]= KeySta[j] ; //这句错了。backup[i]不是一个左值。本回答被提问者和网友采纳
