The program accepts X and Y. Depending on the value of X and Y we need to determine on which quadrant this point lies. #include <stdio.h> void main() { int x, y; printf("Enter the values for X and Y\n"); scanf("%d %d", &x, &y); if (x > 0 && y > 0) printf("point (%d, %d) lies in the First quandrant\n"); else if (x < 0 && y > 0) printf("point (%d, %d) lies in the Second quandrant\n"); else if (x < 0 && y < 0) printf("point (%d, %d) lies in the Third quandrant\n"); else if (x > 0 && y < 0) printf("point (%d, %d) lies in the Fourth quandrant\n"); else if (x == 0 && y == 0) printf("point (%d, %d) lies at the origin\n"); }
