Problem:- Program to count Number of the Positive and negative number in a 1-D integer Array. Means you have to count a positive and negative number in an Array

Check This:- Hacker rank solution for Strings, Classes, STL, Inheritance in C++.

Logic:- For this problem simple fact you have to know that if the number is greater than zero then the number is positive if the number is less than the number is negative otherwise the number is zero. So for this problem, we have two variable one for positive number and another for the negative number and as I said above we compare the number with zero or if the number is greater than zero we will increase the positive variable by one for negative increase negative variable by one. Before solving follow C Program To Check Number Is Positive Or Negative

 Solution:-

 #include<iostream>
using namespace std;
int main()
{
  int a[100],i,n,zero=0,pos=0,neg=0;
 
cout<<"Enter The Size of An Array :\n";
  cin>>n;

  cout<<"Enter The Element :\n";
  for(i=0;i<n;i++)
  {
  cin>>a[i];
  }

  cout<<"Elment in Array is Given Below\n";
  for(i=0;i<n;i++)
  {
  if(a[i]>0)
  pos++;
  else if(a[i]<0)
  neg++;
  else
  zero++;
  }
  cout<<"\nPositive No. is = "<<pos;
  cout<<"\nNegative No. is = "<<neg;
  cout<<"\nTotal Zero in array is = "<<zero;
 return 0;

}

 Output:-

    Below there is an Array of positive and negative number. Write a program that calculates how many of the numbers are positive and how many of them are negative. A [ ] = {10, -2, 9. -4, -6, -7, 12, 14, 19, -20}

    You are askig same Query. I think you are searching for C++ Program To Check Number Is Positive Or Negative If you have any Other Query send a Email.

    Your Solution Is

    /*

    */

    #include

    using namespace std;

    int main()
    {
    int n, i,countneg = 0 , countpos = 0, countzero = 0;

    cout<<"Enter The Array Size: ";
    cin>>n;

    int arr[n];

    cout<<"\nEnter The Array Elements: \n";

    for(i = 0; i < n; i++)
    {
    cin>>arr[i];
    }

    for(i = 0; i < n; i++)
    {
    if(arr[i]<0)
    {
    countneg++;
    }
    else if(arr[i]>0)
    {
    countpos++;
    }
    else
    {
    countzero++;
    }
    }

    cout<<"\n\nTotal Number of Positive Elements in An Array is: "<<countpos;
    cout<<"\nTotal Number of Negative Elements in An Array is: "<<countneg;
    cout<<"\nTotal Number of Zero Elements in An Array is: "<<countzero;

    return 0;
    }

      Hello, Sahni

      we know that in Header file we use less than and greater than symbol, But this page compile the whole page except page body that is why header files are not showing. So don't worry about header file everybody knows header files in C/C++.

    Good Evening sir i need a little help in this html program
    Write a HTML code to generate following output
    Create the following tables ( primary keys are underlined.).
    Sales_order(s_order_no,s_order_date)
    Client(client_no,name, address)
    A clinet can give one or more sales_orders , but a sales_order belongs to
    exactly one client. Create the Relations accordingly, so that the relationship is
    handled properly and the relations are in normalized form (3NF).
    a) insert 2 client records into client table
    b) insert 3 sales records for each client
    c) change order date of client_no ’C004’ to 12/4/08
    d) delete all sale records having order date on 10th feb. 08
    e) delete the record of client “joshi”
