[Title description]
There is a square, the coordinates of the four corners (x, y) are (1, -1), (1, 1) , (-1, -1), (-1, 1), x is the horizontal axis, and y is the vertical axis. Write a program to determine whether a given point is within the square (including the square boundary). If the point is inside the square, output yes, otherwise output no.
[Input]
Input a line, including two integers x, y, separated by a space, indicating coordinates (x, y).
[Output]
Output one line, if the point is in the square, output yes, otherwise output no.
【Input sample】
1 1
【Output sample】
yes
#include<iostream>

if(x>=(-1)&&x<=1&&y>=(-1)&&y<=1)
cout << "yes" << endl;
else
cout << "no" << endl;
return 0;
