 Print Matrix

/* C program to print matrix in the wave from */
#include<stdio.h>
int main()
{
 int matrix[100][100];
 int m, n, i, j;
 
 printf("Enter number of rows: ");
 scanf("%d",&m);
 printf("Enter number of columns: ");
 scanf("%d",&n);
 
 printf("Enter matrix elements: \n");
 for(i=0;i<m;i++)
 {
  for(j=0;j<n;j++)
  {
   scanf("%d",&matrix[i][j]);
  }
 }
 j=0;
 while(j<n)
 {
  /* Print odd columns */
  for(i=0;i<m;i++)
  {
   printf("%d ",matrix[i][j]);
  }
  /* increment for even columns */
  j++;
  if(j<n)
     {
      /* print even columns */ 
      for(i=m-1;i>=0;i--)
      {
