a) use an extra downcounter which starts at the last element

b) one difference means the result is false,

**BUT**true only when all done

c) write some test data to call your function

See more:

int isReverse (char array_a[], char array_b[], int size) {

}

//I know how to do the compare part but I'm stuck on the reverse order part

// I'm don't know how to check char arrays if they have the same character in reverse order

**What I have tried:**

int isReverse (char array_a[], char array_b[], int size) {

for (int i=0; i < size; i++)

{

if (array_a[i] != array_b[i])

return false;

else

return true;

}

}

//I know how to do the compare part but I'm stuck on the reverse order part

// I'm don't know how to check char arrays if they have the same character in reverse order

int isReverse (char array_a[], char array_b[], int size) {

for (int i=0; i < size; i++)

{

if (array_a[i] != array_b[i])

return false;

else

return true;

}

missing tips:

a) use an extra downcounter which starts at the last element

b) one difference means the result is false,**BUT** true only when all done

c) write some test data to call your function

Take a sheet of paper and pencil and try to solve by hand.

Choose a sample, write the 2 arrays, write the position of each char, make a table with positions of chars you have to check in both arrays.

Write another example with another size.

Find the mathematical relation between the char check positions in both arrays. This is very simple maths, if you can't deal with it, have a talk with your teacher, because you have a big problem.

We do not do your HomeWork.

HomeWork is not set to test your skills at begging other people to do your work, it is set to make you think and to help your teacher to check your understanding of the courses you have taken and also the problems you have at applying them.

Any failure of you will help your teacher spot your weaknesses and set remedial actions.

Any failure of you will help you to learn what works and what don't, it is called 'trial and error' learning.

So, give it a try, reread your lessons and start working. If you are stuck on a specific problem, show your code and explain this exact problem, we might help.

As programmer,

When you just ask for the solution, it is like trying to learn to drive a car by having someone else training.

Creating an algorithm is basically finding the maths and make necessary adaptation to fit your actual problem.

Think abut it: it's not complicated.

Start by checking the lengths: if they are different, they don't match.

It that's fine, compare the last element of one array with the first element of the other. That's easy

If they are the same, compare the last but one element of one array with the second element of the other. That's easy

And so on, until you have done them all.

And a little bit of thought will show you how to do that in a loop ...

`x[0]`

vs `y[0 + len - 1]`

Given the function signature, the OP cannot check the lengths of the array.

Given that they are char arrays, chances are they are null terminated strings. If not, he needs to supply the length(s) or it can't be done!

Hey man, you cannot code on 'chances'. :-D

Half of QA is coding on "guesses", so I'm allowed to code on "chances" :laugh:
