C Program to Sort a Matrix Column wise using Pointers
This is a c program to sort a mxn matrix column wise in ascending order using pointers. To sort column wise in descending order, just replace the '>' symbol in the comparing line of code into '<'. That part of the code is marked with a comment 'comparison'.
#include<stdio.h> main() { int a[7][7],i,j,k,m,n,temp; //reading printf("enter number of rows of matrix\n"); scanf("%i",&m); printf("enter number of columns of matrix\n"); scanf("%i",&n); printf("enter the elements\n"); for(i=0;i<m;i++) { for(j=0;j<n;j++) scanf("%d",&a[i][j]); } //displaying printf("the matrix you entered:\n"); for(i=0;i<m;i++) { printf("\n"); for(j=0;j<n;j++) { printf("%4d",*(*(a+i)+j)); } }
