Hello, I want this program to process 2 washers, in this case washerA and washerB, I must not pass any parameters in function calls.Code:#include <stdio.h> #include <math.h> double quantity1, thickness1, density1, inner1, outer1; double product, area; double washerA; /* Prototypes */ void ReadData (void); double FindProd (void); double CircleArea (void); void PrintResult (void); int main(void) { /* Body of Control */ ReadData (); product=FindProd(); area=CircleArea(); washerA=product*area; PrintResult(); return 0; } void ReadData (void) { scanf ("%lf %lf %lf %lf %lf", &quantity1, &thickness1, &density1, &inner1, &outer1); } double FindProd (void) { double product; /* local variable */ product = quantity1*thickness1*density1; return (product); } double CircleArea (void) { double area; /* local variable */ area = ((3.142*(pow(outer1/2,2)))-(3.142*(pow(inner1/2,2)))); return (area); } void PrintResult(void) { printf ("%0.2lf, %0.2lf\n",product,washerA); }
