Float in java and c++...( a beginner issue)

Question

Hello there!
I'm trying to write a code to find the slope of two points but both of my code in c++ and java keep giving me int results or 0.0 even when i declared all my variables in float or double

Answer 1

Angel there is a little mistake.
See this line:
float slope = ((y2-y2)/(x2-x1));

Did you notice you are subtracting y2 from y2 that is y2-y2.
You just need to write y2-y1 in that place. ☺

and one more you have declared variable y on line 12 not y1 so do change it.

You'll understand this after writting few more programs.. keep practicing. Improve debugging skill.
All the best. Never give up 😊

Answer 2

Angel you are welcome.
And I'll suggest you to use another IDE for learning java as handling multiple inputs and finding bugs is quite hard here on sololearn.

If you have PC you can try intellIJ IDEA or Eclipse.

A good way to practice on Android is to use Jvdroid. You can search for others also..
Here is link to Jvdroid
