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;
}

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}

Header files are
Delete#include<iostream>
#include<cstring>
I don't know Why header files are not working....
DeleteHello, Sahni
Deletewe 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++.
Marvelous and fascinating article. Incredible things you've generally imparted to us. Much obliged. Simply keep making this kind out of the post.
