Hi: I use c8051f410,
Program Size: data=114.1 xdata=100 code=4633
I had to use the long multiple in program and find it can not be excecute properly.
The code is as below, Is this stack overflow? How can I fix it?
long x=0; char cHour=0xff; char cMin=0xff; char cSec=0xff; long gulbegintime=0; x=(ulong)3600*(ulong)cHour; printf("1 x =%lu \n",x); gulbegintime=60*cMin; printf("2 gulbegintime =%lu \n",gulbegintime); gulbegintime+=cSec; printf("3 gulbegintime =%lu \n",gulbegintime);
print result:
1 x =4294963696 2 gulbegintime =4294967236 3 gulbegintime =4294967235
OF COURSE I MEANT I RAISED A GOOD POINT.
