Question

Objective: This assignment is a grab bag of practice problems with an emphasis on strings, vectors, and File Input/Output and more practice with functions. Specification: Write functions to perform the indicated task. Most of the functions are short and can be written in a handful of lines. Each function should use the most optimal solution. Please test your functions within main). Leave all your test code active in main) so it can be reviewed in a hanful of lines. Each function should use the most optimal solution. Please test your

Explanation / Answer

16
double degreesToRadian(double degrees) {
   degrees = fmod(degrees,360);
   return 3.14159265359 * degrees / 180;
}

17
struct cpair {
   double x;
   double y;
};

double findSlope (struct cpair a, struct cpair b) {
   double slope;
   slope = (b.y - a.y)/(b.x - a.x);
   return slope;
}

double findYIntercept(struct cpair a, struct cpair b) {
   double c;
   double m = findSlope(a,b);
   c = a.y - m * a.x;
   return c;
}

18
void rectangle (struct cpair a, struct cpair b, double *length, double *breadth, double *area) {
   *length = abs(a.x - b.x);
   *breadth = abs(a.y - b.y);
   *area = (*length) * (*breadth);
}
