Separate positive and negative numbers in an array

Problem statement:- Program to Separate positive and negative numbers in an array.

Data requirement:-

   Input Data:- arr,size

  Output Data:-arr

  Additional Data:- i, j

Program in C

Here is the source code of the C Program to Separate positive and negative numbers in an array.

Code:

#include<stdio.h>
int main()
{
    printf("Enter the size of the array:");
    int size;
    scanf("%d",&size);
    int arr[size],j,i;

    printf("Enter the Element of the array:\n");
     for(j=1;j<size;j++)
    {
        scanf("%d",&arr[j]);
    }
   printf("\nPositive numbers are:");
    for(i=0;i<size;i++)
    {
        if(arr[i]>0)
        {
            printf("%d ",arr[i]);
        }
    }
    printf("\nNegative numbers are:");
    for(i=0;i<size;i++){
        if(arr[i]<0)
        {
            printf("%d ",arr[i]);
        }
    }
    }

Input/Output:

Code:

#include<iostream>
using namespace std;
int main()
{
    cout<<"Enter the size of the array:";
    int size;
    cin>>size;
    int arr[size],j=0,i;
    cout<<"Enter the Element of the array:\n";
     for(j=0;j<size;j++)
    {
    cin>>arr[j];
    }

    cout<<"\nPositive numbers are:";
    for(i=0;i<size;i++)
    {
        if(arr[i]>0)
        {
            cout<<arr[i]<<" ";
        }
    }

    cout<<"\nNegative numbers are:";
    for(i=0;i<size;i++){
        if(arr[i]<0)
        {
        cout<<arr[i]<<" ";
        }
    }
    }

Input/Output:

Enter the size of the array:5
Enter the Element of the array:
-35
-78
56
74
35

Positive numbers are:56 74 35
Negative numbers are:-35 -78

Program in Java

Here is the source code of the Java Program to Separate positive and negative numbers in an array.

Code:

import java.util.Scanner;
public class p19 {

public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
System.out.println("Enter the size of the array:");
    int size;
    size=sc.nextInt();
    int arr[ ]=new int[size];
int i,j=0;
System.out.println("Enter the Element of the array:");
     while(j<size)
    {
        arr[j]=sc.nextInt();
        j++;
    }
     System.out.println("Positive numbers are:");
     for(i=0;i<size;i++)
     {
         if(arr[i]>0)
         {
        System.out.print(arr[i]+" ");
         }
     }

     System.out.println("\nNegative numbers are:");
     for(i=0;i<size;i++){
         if(arr[i]<0)
         {
        System.out.print(arr[i]+" ");
         }
     }
    sc.close();
    }}

Input/Output:

Enter the size of the array:
4
Enter the Element of the array:
-3
5
-78
44
Positive numbers are:
5 44 
Negative numbers are:
-3 -78 

Program in Python

Here is the source code of the Python Program to Separate positive and negative numbers in an array.

Code:

arr=[]
size = int(input("Enter the size of the array: "))
print("Enter the Element of the array:")
for i in range(0,size):
    num = int(input())
    arr.append(num)
print("\nPositive numbers are:")
for i in range(0,size):
    if(arr[i]>0):
        print(arr[i],end=" ")

print("\nNegative numbers are:")
for i in range(0,size):
    if(arr[i]<0):
        print(arr[i],end=" ")

Input/Output:
