Positive and negative numbers

4
Locked

Data analysis starts with a simple concept: we need to understand what data matters and should be used, and what data should be discarded. Let's solve a simple data analysis problem. We enter three integers from the keyboard, then we'll analyze them and display the number of positive and negative numbers in the source set.

what does point 3 and 4 of the requirements mean? The program should display the number negative numbers in the original set. The program should display the number of positive numbers in the original set. I am not passing on this, despite getting the right output

create an else statement that doesn't do anything. I just wonder how practically applicable in a real coding situation. I guess I'll eventually find out! Happy coding.

you need two if statements, one (a>0) and another a<0, by doing this you skip counting in the zero.

Please, I need guidance in regards to " Note that 0 is not a positive or negative number. ". I can not pass it. Here is my source code: https://pastebin.com/xrFu2d5V I paste it here, because I exceeded the character limit.

For anyone struggling on the last case, create a condition that does nothing if the value is 0. :D

int a = 0;
       int b = 3;
       if(num1>0){
           a++;
           b--;
       }if(num2>0){
           a++;
           b--;
       }if(num3>0){
           a++;
           b--;
       }else if(num1==0){
           // a++;
           // b--;

       System.out.println("Number of negative numbers: "+b);
       System.out.println("Number of positive numbers: "+a);

you have 2 problems that i can see 1: you should make separate if statements for your inputs 2: you don't need to subtract 1 from one variable and add to another you can just add to one of them
