Answer:
C++ Program .
#include<bits/stdc++.h>
using namespace std;
int main()
{
int x,y;//declaring two variables x and y.
string s;//declaring string s..
cout<<"enter x and y"<<endl;
cin>>x>>y;//taking input of x and y..
if(x>=0 &&y>=0) //condition for 1st quadrant..
cout<<"the point lies in 1st Quadrant"<<endl;
else if(x<=0 &&y>=0)//condition for 2nd quadrant..
cout<<"the point lies in 2nd Quadrant"<<endl;
else if(x>=0 &&y<=0)//condition for 3rd quadrant..
cout<<"the point lies in 3rd Quadrant"<<endl;
else //else it is in 4th quadrant..
cout<<"the point lies in 4th Quadrant"<<endl;
cout<<"enter n to terminate the program"<<endl;
while(cin>>s)//if the user has not entered n the program will not terminate..
{
if(s=="n")
{
cout<<"the program is terminated"<<endl;
exit(0);
}
cout<<"you have not entered n please enter n to terminate the program<<endl;
}
}
Explanation:
The above written program is for telling the point lies in which quadrant.I am first declaring two variables x and y.Then after that taking input of x and y after that checking in which quadrant the point lies.
Taking input of the string s declared earlier for program termination the program will keep running until the user enters n.
