怎么输出 21 分制时输出了一堆 11:0？？？

#include <bits/stdc++.h>
#define W 0
#define L 1
using namespace std;

      if (max(w1,l1)>=11&&abs(w1-l1)>=2) {

        record1[record1_cnt][L]=l1;

      }

      }
    }
  }
  record1[++record1_cnt][W]=w1;
  record1[record1_cnt][L]=l1;
  record2[++record2_cnt][W]=w2;
  record2[record2_cnt][L]=l2;
  for (i=1;i<=record1_cnt;i++)
    printf("%d:%d\n",record1[i][W],record1[i][L]);
  for (i=1;i<=record2_cnt;i++)
    printf("\n%d:%d",record2[i][W],record2[i][L]);
  return 0;
