C Program To Check If Point Lies on x-axis or y-axis or Origin


Given a point (x, y), write a C program to find out if it lies on the x-axis, y-axis or on the origin(0, 0).

Important: Always remember that, to specify a point, we always write x-axis value first and then the y-axis value. i.e., (x, y)

Logic To Check If Point(x, y) Lies on x-axis or y-axis or Origin
In point (x, y), if x = 0 and y = 0, then the point lies on the origin. If value of x is zero and y is greater than zero, then the point lies on y-axis. If y is zero and x is greater than zero, then the point lies on x-axis.

User Input:
Enter the point(x, y)
0
5

Output:
Point lies on y-axis

Source Code: C Program To Check If Point Lies on x-axis or y-axis or Origin

#include < stdio.h >

int main()
{
    float x, y;

    printf("Enter the point(x, y)\n");
    scanf("%f%f", &x, &y);

    if(x == 0 && y == 0)
    {
        printf("Point lies on the Origin\n");
    }
    else if(x == 0)
    {
        printf("Point lies on y-axis\n");
    }
    else if(y == 0)
    {
        printf("Point lies on x-axis\n");
    }
    else
    {
        printf("Point neither lies on x-axis nor on y-axis\n");
    }

    return 0;
}

Output 1:
Enter the point(x, y)
0
0
Point lies on the Origin

Output 2:
Enter the point(x, y)
5
0
Point lies on x-axis

Output 3:
Enter the point(x, y)
0
5
Point lies on y-axis

Output 4:
Enter the point(x, y)
5
5
Point neither lies on x-axis nor on y-axis
