C programming Write a function definition for a userdefined

C programming

Write a function definition for a user-defined function that calculates the (floating-point double) Percent Difference between two experimental double values, A and B. Percent Difference = |A - B/(A+B/2| * 100% Write a function definition for a user-defined function that calculates the (floating-point double) Percent Error between a known double value, A, and an experimental double value B. Percent Error = |A - B/A|* 100%

Solution

#include <stdio.h>
#include <math.h>
double percentDifference(double A, double B)
{
return fabs((A - B)/((A + B) / 2)) * 100;
}
double percentError(double A, double B)
{
return fabs((A - B) / A) * 100;
}
