C++ Array Question

[Juggler]

I have a question about manipulating an array in C++. In my program, a cstring is entered. The string is printed. Finally, the string must be printed in reverse and displayed.

The final part is where I am having my problem. I have the strlen function determine the legnth of the function, and I was then going manipulate the string by having the array go to the last character of the string entered, and then print each of the characters by cycling through the c-string backwards.

I am having trouble with this. I can't seem to figure out how to get the strlen function to be the starting point of the array. Any suggestions?

Thank you.

i hope i can help you with this simple example


char *a ="jessy";
cout<<" your string Reversed.."<<en dl;
for ( int i=strlen(a);i >=0 ;i-- )
{
cout<<a[i]<<endl<<endl;
try this code

try this code

In char *a, what is the * for. I've never seen that before.

Would this work though? The userInput is the original string. reversedUserInp ut is the the string that userInput is copied to. I get an error at the first line of code that I've attached.

strcpy(reversedUserInput, userInput, strlen(userInput));
for (reversedUserInput; i >= 0; i--)
{
  cout << "The string reversed:\n" << reversedUserInput << endl;                
}

Would this be close to be working? I can't seem to get what is wrong with the first line of code there.

Figured it out. strcpy should have been strncpy and then there were other random errors too.

Good Luck !!

BUt you stiLL dont't Know what the * is ????????

this is POINTER ... haven' t you ever heared oF pointers Before ????!!!!!

i guess they are very Important In learning c and c++
so char *a is a pointer to a character array containing your string (user input)
