I need to have the program calculate the area of a circle from the inputs, converting degrees to radians, and checking for correct inputs such as letters instead of numbers or negative lengths. Here is the code I have:

The problem is I get this when I try to run it as well as not accepting the lower case 'y':Code:#include <stdio.h> #include <stdlib.h> #include <math.h> #define PI 3.1415926 int main() { double base; double angleD; double angleR; double area; int in; char buffer[128]; while (1) { printf("Would you like to continue?(Y/N) "); if((in = getchar()) == 'Y' || (in = getchar()) == 'y') while (1) { printf("Enter Base Length and Angle in degrees(Less than 90): "); gets(buffer); int x = sscanf(buffer, "%lf %lf", &base, &angleD); if(x == 2) { if(base > 0 && angleD > 0) { angleR = angleD * PI / 180; area = base * base * tan(angleR) / 2; printf("Area is %7.4f\n", area); break; } else { printf("No Negative Numbers Please\n"); } } else { printf("Please enter numbers only.\n"); } } else { printf("Thank you!\n"); break; } } }

Would you like to continue?(Y/N) Y

Enter Base Length and Angle in degrees(Less than 90): Please enter numbers only.

Enter Base Length and Angle in degrees(Less than 90):

I know it's a mess but I'm out of ideas and so are the other people I know who have any C experience. If you need anything cleared up let me know
