question mark or exclamantion point and store it in separate
char varible. Then use a second loop to search backward through the array for the begging og the last word. Print the last word then search backward for the next-to-lat word. Repeat until beginning of the array is reached. Finnaly print the termination character.

(1) one is to pass a pointer-to-pointer parameter, like:
int my_malloc(int size, char **pmem)
{
*pmem=(char *)malloc(size);
if(*pmem==NULL)... (11 Replies)
