如何以降序方式对2D数组排序

Question

How can i sort an 2D array in a descending way, without using pointers im still a beginner.

Fore example if i input an 2D array 2x2. With the following elements: 2 3 1 5 The output should be: 5 3 2 1

Answer 1

for(i=0;i<row;i++)
 for(j=0;j<col;j++)
  for(k=0;k<row;k++)
   for(p=0;p<col;p++)
    if(a[i][j]>a[k][p])
      temp=a[i][j]; a[i][j]=a[k][p]; a[k][p]=temp;

This worked for me
