[aliz_khanz]

Homework Statement

Write a function reverse which inverts the order of character in the text array.
void reverse(char s[])
// s[] – the array containing the character which order has to be inverted
Apply this funtion in a program which inverts the characters in all input lines.

Homework Equations

Scanf maybe ...%"anything"

The Attempt at a Solution

I don't really know where to start as I am unable to understand the question. Can anyone please write this programme for me? I just know that scanf function will be used in order to write the programme.

No, we aren't going to write this program for you. That's not what we do here. We're happy to help you, but you need to make some effort at solving this problem before we can help.

If the user enters the string, "Hi, how are you?" the program should reverse the characters to produce this string "?uoy era woh ,iH"

Hints,

The last character in the array should be a null, use that to get the length. Try looking up a swap function. Are you familiar with loops? Also I don't see a use for scanf?
