hello everyone;

can anyone tell me whats wrong with this simple code??

#include <iostream>

#include <cmath>


int main()
{
int x;

cout<<"enter a number ";
cin>> "x";
cout<< sqrt( x );





return 0;
}

might want to use a float for x instead of integer, especially if you're squarerooting.

#include <iostream>

#include <cmath>


int main()
{
float x;

Here´s your solution:

#include <iostream>
#include <stdlib.h>
#include <cmath>


int main(){

int x;

cout<<"enter a number ";
cin>> x;
cout<< sqrt( x );

system("PAUSE") ;
return 0;
}

I tested and it works. The problem in your code was in the input of x, on your code u have the statement cin>>"x".

Sorry wasn't looking hard enough. You were saving into a character x instead of float variable x.

#include <iostream>
#include <cmath> 
#include <conio.h>
using namespace std;

int main()
{
float x;

cout << "enter a number: "; cin >> x;
cout<< sqrt( x ); 

getche();
return 0;
}

x doesnt need to be float

Have you received the answer you require?

One of the problems people have had answering your question is that you never actually stated what the original problem was. You should have described the output you where getting and the output you where expecting.
