Matrix column mirror like rearrange in C [SOLVED] -

i have first insert number of rows , columns, elements , show whole matrix. after arrange columns in mirror way. example: if matrix has 1 row , 5 columns, should this:

matrix 1 2 3 4 5 should become 5 4 3 2 1

the same thing goes more 1 row.

this did far:

#include <stdio.h>  void main() {     int m, n, i, j, matrix[10][10];     printf("insert number of rows , columns:\n");     scanf("%d%d", &m, &n);     printf("insert desired elements:\n");     (i = 0; < m; i++)         (j = 0; j < n; j++)             scanf("%d", &matrix[i][j]);     printf("your matrix has following elements:\n");     (i = 0; < m; i++)     {         (j = 0 ; j < n; j++)         {             printf("%d\t", matrix[i][j]);         }         printf("\n");     } } 

if there better way, or did wrong, please tell me.

solved added following:

printf("your new matrix has following elements:\n"); (i = m-1; >= 0; i--)     {         (j = n-1 ; j >= 0; j--)     {         printf("%d\t", matrix[i][j]);     }     printf("\n");     } 

thanks jonathan leffler idea.

^{transferring comment answer.}

you've got moderately start; need show code print data in reverse order — presumably counting down instead of counting up, @ least in inner loop , possibly in both loops.

your data entry code should check scanf() succeeds each time, , should check neither m nor n bigger 10 (or less 1, less dangerous; won't in relevant loop).

bug: counting 1..m , 1..n, in c, array indexes go 0..m-1 , 0..n-1.
