[kobe67]

Create a program that will ask a string from the user, your program should automatically exchange the 1st & the last letter of every word in the string

One way of doing this is to initialize a string with a sentence and allocate pointers to the 1st and last letters of the first word.

string s ="When will you be back";
*p1=&s[0];
*p2=&s[3];
swap(p1,p2) // prints ' nheW'

Now use a for loop to change the remaining four words with the following within its body.
p2+=2; //points to the 1st letter in next word
p1=p2; // p1 does the same and is where you want it
Then advance p2 to the last letter in 2nd word by:
while(p2>='a' && p2<='z') p2++;//it will go too far (to the space) so p2- - outside the while loop.
now swap(*p1,*p2);

try to use strtok to locate the words in a sentence and then swap the first letter and last letter of this word.

Nope. Unless you know how to grab and work on each individual token and then reverse tokens back to a string.
