If you want your value to be in units of kilometers multiple d by 1609344. Calculating the distance in C. Looping computation of cvnorma adding the result to a variable and updating variable a by adding another point takes on my computer about 5 times longer for 9000 loops 1000000000 than computation of sqrtaxax ayay azaz and doing the same other stuff in c code didnt check assembler code.
As a stand-alone function it would take two Points as parameters.
In a two dimension plane there are two points lets say A and B with the respective coordinates as x1 y1 and x2 y2 and to calculate the distance between them there is a direct formula which is given below x2 x12 y2 y12 Given below is the diagram representing two points and their differences. A get_value Point x for second coordinate. The formula for distance between two point x1 y1 and x2 y2 is. Find distance between two nodes of a Binary Tree in C Program.
