二进制数的1的补码和2的补码是什么？

1’s Complement of 101100 = 010011

2’s complement of 101101 is 010011.

#include <iostream>
#include<string.h>
using namespace std;
int main() {
   char binary[10] = "01001011";
   cout<<&ldquo;Binary number is &rdquo;<<binary;
   //once complement....
   int length = strlen(binary);
   for(int i=0;i<length;i++) {
      if(binary[i] == '0') {
         binary[i]= '1';
      } else
         binary[i] = '0';
   }
   cout<<&ldquo;One&rsquo;s Complement is &rdquo;<<binary<<endl;
   // cout<<binary[length-1];
   for(int i = length-1; i>=0; i--) {
      // cout<<binary[i];
      if(binary[i] == '0') {
         binary[i] = '1';
         //cout<<binary[i];
         break;
      } else {
         binary[i] = '0';
      }
   }
   cout<<&ldquo;Two&rsquo;s complement is &rdquo;<<binary;
   return 0;
}

Binary number is 01001011
One’s complement is 10110100
Two’s complement is 10110101
