problem with code

[php]

#include<iostream>
#include<string>
using namespace std;
int main()
{
char a[10000],b[100];
cout << "enter the string.";
cin >> a;
cout << "enter the string to find";
cin >> b;
int n=a.find(b);
cout << n << "\n";
}
when i use string instead of char and then i enter this is
then this i s considered the first and is the second value

a is a char array and arrays don't have any member functions like find(). That is one of the benefits of using std::string rather than a char array.

[php]

still the same porblem

I think you can't even enter the char array this way either:

char a[10000],b[100];
cout << "enter the string.";
cin >> a;

I think you need to enter each element of the array alone. In this case a is the pointer to the first element of array a[10000], so you need a syntax like a[i] or *(a+i) to get the elements of the array. Use string instead unless you have a good reason to use an array of chars.

[php]

i dont want a array i want i string
but when i use std::string or string
and enter this
this is
then this is considered a and is b

[Galik]

If you want to use a std::string then std::getline() may be what you're looking for:

std::string a, b;

std::getline(std::cin, a);

it works thanks , thansk to all
i am new to c++ can you tell me how to create a onkeyup function like we do in javascript

That's gonna be a lot trickier. Working with hardware and drivers and stuff can be a pain. I'm pretty sure SFML has a uparrow function, so give that a try: http://www.sfml-dev.org/

The internet has exabytes of information. Googling something takes about 5 seconds. Go and do some research!
