C program: Sorting Matrix Elements

Requirement:

Write a program to sort the elements of m x n matrix A in descending order. Suppose M and N do not exceed 10. Write the functions to calculate the largest element value and the smallest element value in one-dimensional array respectively. The main function initializes a two-dimensional array a [10] [10], call the defined two functions to output the maximum values of each row and column.

Code:

// MatrixSort.cpp : Defines the entry point for the console application.//#include "stdafx.h"#include iostream.h>void bubble_sort(int a[],int n){    int temp=0;    for( int i=0;in;i++ )    for(int j=n-1;j>i;j--)    {        if(a[i]a[j])        {            temp=a[i];            a[i]=a[j];            a[j]=temp;        }    }}void bubble_sort2(int** a,int n){    int temp=0;    for( int i=0;i
 
   )    for(int j=n-1;j>i;j--)    {        if(**(a+i)**(a+j))        {            temp=**(a+i);            **(a+i)=**(a+j);            **(a+j)=temp;        }    }}void formatMatrix(int* matrix, int linesize , int columnsize){for(int j=0 ; jcolumnsize ; j++){int** col = new int*[linesize] ;for(int i=0 ; ilinesize ; i++ )*(col+i) = matrix+i*columnsize+j;bubble_sort2(col ,linesize ) ;delete[] col ;}}void showMaxAndMin(int* matrix, int linesize , int columnsize){int* max = new int[columnsize] ;int* min = new int[columnsize] ;for (int i=0; icolumnsize; i++){max[i] = *(matrix+i) ;min[i] = *(matrix+(linesize-1)*columnsize+i) ;}coutendl
