Reply To: invalid operands of types `float’ and `int’ to bin

Hello
 
Well there is a sligh problem with your code. You are using ^ as a power operator but there is no such operator which performs the power operations. This operator (^) is a bitwiase operator to calculate XOR.

To calculate the power you can use pow(double x, double y) function. It will calculate x power y. 
 
Also make sure you include math.h header in your program as pow function is defined is this header file. 
 
So your function should look like

void circle()<br /> {<br />  double r=0.0;<br />  double m=2.0;<br />  double area=1;<br /> printf("enter area");<br />  scanf("%lf",&#038;r);<br />  area =PI* pow(r,m);<br />  printf("%lf",area);<br />  getch();<br /> }

1 2 3 4 5 6 7 8 9 10 11

void circle()<br /> {<br />  double r=0.0;<br />  double m=2.0;<br />  double area=1;<br /> printf("enter area");<br />  scanf("%lf",&#038;r);<br />  area =PI* pow(r,m);<br />  printf("%lf",area);<br />  getch();<br /> }
