Explanation / Answer

#include<stdio.h>
int main() {
   int i = 0;
   char c, message[1000] = "";
   printf("Enter a message: ");
   while(1){
       c = (char)getchar();
       if(c == ' ') break;
       message[i++] = c;
   }
   i--;
   printf("Reversal is : ");
   while(i>=0) {
       printf("%c",message[i--]);
   }
   return(0);
}

reverseP.c

#include<stdio.h>
int main() {
   char *p;
   char c, message[1000] = "";
   printf("Enter a message: ");
   p = message;
   while(1) {
       c = (char)getchar();
       if(c == ' ') break;
       *p = c;
       p++;
   }
   printf("Reversal is : ");
   while((p - message) >= 0) {
       p--;
       printf("%c",*p);
   }
   return(0);
