Reverse the input of a string. Visual Studio 2017

Question

For a school project I have the following code I have to write:

Ask the user a first name, then a last name. Stop these values in two
different arrays, of the right type. Use one or more loops of your choice first
just print the name and then print the name in reverse order

The following code I already have:

int main ()
{
char first_name[20];
char last_name [20];
char total_name [100];
char reversed [100];
int counter = 0;

printf ("Enter your first name:");
gets_s (first_name);

printf ("Enter your last_name:");
gets_s (last_name);

strcpy_s (total_name, first_name);
strcat_s (total_name, "");
strcat_s (total_name, last_name);

while (counter == 0)
{
printf ("Your name is: %s", total_name);
counter ++;
}
_getch ();
     return 0;
}

How do I reverse this string, so that when I give in Dave Jaski it gives iksaJ evaD in return.

thanks!

How do I reverse this string

By using one or more loops of your choice, of course. The assignment seems clear.

Thanks for your answer.

the output shoot look like this:

What is your name: Janssen
What is your first name: Jan
So you are Jan Janssen.
In reverse order it is: nessnaJ naJ

But I don't know how I have to reverse the input with the loops.

The assignment requires that you store the data in arrays.  So how can you access the individual elements of an array to retrieve its value or store a different value to the array element?

Thanks. 

I think i figured it out

Answer 5

While you are at it, what is the purpose of the while loop?  Hopefully you realize it can never iterate more than once.
