while i am using int function in c one extra output is coming
#include<stdio.h>
int cir(float r)
{
float dia,circum,are;
dia=2*r;
circum=(2*3.14*r);
are=(3.14*r*r);
return printf("The circle has diameter %.2f , circumferrence %.2f and Area %.2f ",dia,circum,are);
}
int main()
{
float r;
printf("Enter the radius of a circle: ");
scanf("%f",&r);
printf("%f",cir(r));
return 0;
}
