I made a mistake in the following program

[kamilhassaan]

I recently started C++. I am making this program in which I have to input the value of "x" and the program will calculate the value of "y". Whats the mistake

#include <iostream>
using namespace std;
int main ()

{
	int x,y;
	
	cout<<"Please enter the value of x : "<<endl;
	cin>>x;
	
	y=x*x + 2*x + 1;
	
	return 0;
}

What did you want the program to do? This will determine the answer to your question. As expected it runs ok.

The program computes the value of y and then exits. You need to print the value before exiting.

when i'll input the value of "x", it should substitute the the value of "x" in that equation(y=x*x + 2*x + 1) and and give me the answer

and give me the answer

The answer has been worked out - that's why line 11 was written.

What you need is a new line cout << x;
