I tried to run this pgm in both turbo c&dev,i am getting error in turbo,but in dev it will compile,no res y?

#include%26lt;stdio.h%26gt;





main()


{


int radius;


float area,perimeter;





printf("\n Enter the radius of a circle");


scanf("%d",%26amp;radius);


areaperi(radius,%26amp;area,%26amp;perimeter);





printf("Area=%f",area);


printf("\n Perimeter=%f",perimeter);


}





areaperi(int r, float *a, float *p)


{


*a=3.14*r*r;


*p=2*3.14*r;


}

I tried to run this pgm in both turbo c%26amp;dev,i am getting error in turbo,but in dev it will compile,no res y?
You have to declare the function before main() like this


areaperi(int , float *, float *); or you can move the entire function before main().





The error you are getting in turbo c is because, when the areaperi is encountered while running main, will be unknown.
Reply:You also need to declare the return type of the functions:


int main()


float areaperi(int,float*,float*)
