P1830 轰炸III

洛谷新手村前几题好多模拟，难度也是渐渐上来了。先是一维数组，再是二维，二维坐标时还要注意端点处是否取到

#include<stdio.h>

int main()

  int n, m, x, y, i, j, k, x1, y1, x2, y2;
  scanf("%d %d %d %d", &n, &m, &x, &y);
  int sign[n + 1][m + 1], import[y][2], sigh[n + 1][m + 1];  //sigh记录轰炸的轮数
  for ( i = 0; i < n + 1; i++)
    for ( j = 0; j < m + 1; j++)
      sign[i][j] = 0;

        sigh[i][j] = k;
      }
  }
