Answer 1

#include
#include
int main(){
int i,x,count=0;
scanf("%d",&x);
i=x;
if (x>0&&x<32768)
while (i>0){
i/=10;
count++;
}
printf("x是%d位數 x的個位數=%d\n",count,x%10);
system("pause");
return 0;
}

Answer 2

#include
#include
#include
int main(int argc, char* argv[]){
//=====START=====//
int num;
printf("Input a number: "),scanf("%d",&num);
if(abs(num)<0x8000){
printf("Bit is %d.\nLast bit is %d.\n",(int)(log10(num)+1),num%10);
}
//=====END=====//
system("PAUSE");
return 0;
