How do I go about writing positive, neg, zero, and even or odd???

[joeyke]

Write a complete C++ program, including comments, to do the following:

Ask the user to enter a number, and then read in the number from the keyboard. Print out the number and also output whether the number is positive, negative or zero, and also output whether the number is even or odd.

Notice that these categories are not mutually exclusive. Take them one at a time:

• How do you test if a number is positive?
• How do you test if a number is negative?
• How do you test if a number is zero?
• How do you test if a number is even?
• How do you test if a number is odd?

Edit: Pardon me donbock but you were not there when I started klanking away.
The people here don`t take kindly to spoon feeding the mentally lazy however:
1. If the number can be divided by 2 with 0 remainder it is even and if not it is odd.
2. If the number is less than 0 it is negative.
3. If number when multiplied by 1 == 0, it is 0 (zero)
In future have a go yourself and post your code identifying a specific difficulty
Specifically get your thought processes working. As they say if you don`t use it you loose it!

Have you tried to write the code...? What problem you have in your code.?

line 27 and line 31 have an errors but i don't know what they are

#include <iostream>

using namespace std;

int main ()
{
    int numb1;
    int numb2;


    cout<<" enter one number: ";
    cin>>numb1;
    for (numb1=numb1+0;numb1>0;)
    {
        cout<<numb1<<" is positive";
    }

    for (numb1=numb1+0;numb1<0;)
    {
        cout<<numb1<<" is negative";
    }
        for (numb1=numb1+0;numb1=0;)
    {
        cout<<numb1<<" is zero";
}
for (numb1=numb1+0;numb1%2=0;) //line 27
    {
        cout<<" and is positive";
    }
    for (numb1=numb1+0;numb1%2><0;) //line 31
    {
        cout<<" and  is negative ";
    }
system ("pause");
return 0;

}

You are trying to use for loops when you should be using if statements.
When num1 is typed from the keyboard you need something like:

if (num1>0)cout<<"the number is positive";
else if (num1<0)cout<<"the number is negative";
else cout<<"the number is zero";

Also please enclose your code in code tags by selecting it and hitting #

Use if condition

Actually I dont know , why you are using this much for loop unnecessarily

Use if condition

Refer following code.
