Plastic constant different binary representation

Plastic constant different binary representation:

Code:

#include <stdio.h>  //十进制:%d  八进制:%o  十六进制:%x
int main()   //数: 十进制:128 八进制(前面加零):0128 十六进制:0x128
{
  printf("十六进制0x80的十进制值为:%d\n",0x80);
  printf("八进制0200的十进制值为:%d\n",0200);
  printf("十进制128的十进制值为:%d\n",128);
  printf("十进制128的十六进制值为:%x\n",128);
  printf("十进制128的八进制值为:%o\n",128); 
}
