What this program should do is to enter radius then pick choices....
but it doesn't seem to work
the problem lies with the choice part in which when you type A or a, it will output the radius... when you type B or b circumference... and for C and c --- the area...
Code:
#include <stdio.h>
#include <conio.h>
#define PI 3.14159
int main(void)
{
float r,circ,area;
char c;
clrscr();
printf ("Input Radius:");
scanf ("%f",&r);
printf ("Enter Your Choice\n");
printf ("\n[a] Radius");
printf ("\n[b] circumference");
printf ("\n[c] Area of Circle\n");
scanf ("%f",&c);
c = getche();
if (c == 'a' || c == 'A') {
gotoxy (38,12);
printf ("The radius of the circle is %f", r);
}
else if (c == 'b' || c == 'B') {
gotoxy (38,12);
circ = 2 * PI * r;
printf ("Circumference: %f", circ);
}
else if ( c== 'c' || c== 'C') {
gotoxy (38,12);
area = PI * r *r;
printf ("Area: %f", area);
}
else
{
gotoxy (38,12);
printf ("Invalid Choice");
}
getch();
}
