Reversing string

[vastrolorde]

Is there a command, so that i can read strgin reversed or is there some way to reverse the string.

[Amil Patel]

What do you mean? Basically output a message
string text;
cout<<"Enter a text:";
cin>>text;
when someone or you enter a text it reverse the element of the text so you can read the text backward instead of forwards.
If so Yes there is a way you can do that and it easy.

I don't think there is a function for this so you probably have to make one. Using

char text[number_here]

is easier. You just use a loop, that starts from the end of the array and ends when it becomes 0 (zero) and you copy the elements from text to text_reverse or any other variable.

[vastrolorde]

welll yeah. But i dont know how long the array will be. Amille, what is that way?

[Zu007]

use this code to reverse string
use string header file and write.

cout<<"Enter your text"<<endl;
cin>>b;
cout<<endl<<strrev(b);

[vastrolorde]

So, i can use this strrev with strok? I need to reverse the string and then cut it into pieces, 1 character is 1 substring

[Shinigami]

Do you need string or c_string? If string

string reverse_string(string line) 
{
	string::reverse_iterator it;
	string result;
	for (it = line.rbegin(); it < line.rend(); it++) 
	{
		result += *it;
	}
	return result;
}

There is standard algorithm std::reverse that does what you need

std::reverse( s.begin(), s.end() );

There is also a simple method to define another string which will be equal to the reversed original string. For example

std::string source;

std::cin >> source;

std::string target( source.rbegin(), source.rend() );

[vastrolorde]

so if source is tere then target is eret?

[vlad from moscow]

so if source is tere then target is eret?

That is right.

[vastrolorde]

std::string siht(alge.rbegin(), siht.rend());
This part is causing errors. Whenever it is time to reverse the string, it just crashes.

[vlad from moscow]

It is not this statement that causes the error.

[vastrolorde]

Yes, it is i just noticed :D std::string siht(alge.rbegin(), siht.rend());
If you look carefully, you see that i have alge.rbegin() but siht.rend()

[vlad from moscow]

I did not take this into account because it might be a typo.

[vastrolorde]

That was the problem. Now its working. Ty for your help.
