program keeps crashing along with alot of other errors that i cant figure out how to correct. the program has to ask the user the length and width for two different rectangles and print out the area, perimeter, if its golden and if they're similar and has to use the three files

header

// function to calculate the area double area( double length, double width );

// function to calculate the perimeter double perimeter( double length, double width );

// function to calculate the diagonal length from one corner to another double diagonal( double length, double width );

// function to determine if the rectangle is a square // returns true when it is a square, false when it is not bool isSquare( double length, double width );

// function to determine whether the rectangle is golden // https://en.wikipedia.org/wiki/Golden_rectangle // (a + b) / a is equal to a / b // returns true when it is a golden rectangle, false when it is not bool isGolden( double length, double width );

// function to determine if two rectangles are similar // two rectangles are similar if the ratio of the length and width of // one rectangle is equal to the ratio of the length and width of // the other rectangle bool areSimilar( double length1, double width1, double length2, double width2 );

rectangle.c
