Reversing a two dimensional character array in C

i am trying to write a program which reverses a entire string and also may print reversing each word of the string more than one time. For example my string is: "2 Fox jumps over the lazy dog." for this, the output should be: .god .god yzal yzal eht eht revo revo spmuj spmuj xoF xoF. I am trying to store each word in a 2d array and then reverse each word but i am not able to do that. here is my code. kindly help Note: how do we provide EOF in console

`#include <stdio.h>
 #include <stdlib.h>
 int main()
 {
    char string[100][100];
    char ch;
    int i=0,j=0, l=0, count=0, x=0, y=0;
    while((ch=getchar())!=EOF)
    {
        string[i][l++] = ch;
        if(ch==' ')
        {
           string[i][l] = '\n';
           i++;
           l=0;
           count++;
        }
    }
    for(x=0; x<=count; x++)
    {
       int length = strlen(string[x])-1;
       for(y= length; y>=0; --y)
       {
          printf("%s", string[y]);
       }
    }
    return 0;
}`
