Problem statement:- Program to Find the sum of negative and positive numbers in an array.

Data requirement:-

   Input Data:- arr

  Output Data:-sum_pos, sum_neg, size

  Additional Data:- i, j

Program in C

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

Code:

#include<stdio.h>
int main()
{
    printf("Enter the size of the array:");
    int size;
    scanf("%d",&size);
    double arr[size],sum_pos=0.0,sum_neg=0.0;
    int i=0,j=0;
    printf("Enter the Element of the array:\n");
    while(i<size)
    {
        scanf("%lf",&arr[i]);
        i++;
    }
    while(j<size)
    {       if(arr[j]>0)
                sum_pos+=arr[j];
            else
                sum_neg+=arr[j];
            j++;
    }
    printf("sum of positive number : %0.2lf",sum_pos);
    printf("\nsum of Negative number : %0.2lf",sum_neg);
}

Input/Output:

Enter the size of the array:5
Enter the Element of the array:
-20
30
-55.555
-45
25.8
sum of positive number : 55.80

Program in C++

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

Code:

#include<iostream>
using namespace std;
int main()
{
    cout<<"Enter the size of the array:";
    int size;
    cin>>size;
    double arr[size],sum_pos=0.0,sum_neg=0.0;
    int i=0,j=0;
    cout<<"Enter the Element of the array:\n";
    while(i<size)
    {
        cin>>arr[i];
        i++;
    }
    while(j<size)
    {       if(arr[j]>0)
                sum_pos+=arr[j];
            else
                sum_neg+=arr[j];
            j++;
    }
    cout<<"sum of positive number : "<<sum_pos;
    cout<<"\nsum of Negative number : "<<sum_neg;
}

Input/Output:

Enter the size of the array:4
Enter the Element of the array:
30
-70
88.5
-65.3
sum of positive number : 118.5
sum of Negative number : -135.3

Program in Java

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

Code:

import java.util.Scanner;
public class p5 {

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();
    double arr[ ]=new double[size];
    double sum_pos=0.0,sum_neg=0.0;
    int i=0,j=0;
    System.out.println("Enter the Element of the array:\n");
    while(i<size)
    {
        arr[i]=sc.nextDouble();
        i++;
    }
    while(j<size)
    {       if(arr[j]>0)
                sum_pos+=arr[j];
            else
                sum_neg+=arr[j];
            j++;
    }
    System.out.println("sum of positive number : "+sum_pos);
    System.out.print("\nsum of Negative number : "+sum_neg);

sc.close();
}
}

Input/Output:

Enter the size of the array:
5
Enter the Element of the array:

-30
78.5
-25
55.3
-47
sum of positive number : 133.8
sum of Negative number : -102.0

Program in Python

Here is the source code of the Python Program to Find the sum of negative and positive 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 = float(input())
    arr.append(num)
sum_pos=0.0
sum_neg=0.0
for j in range(0,size):
        if (arr[j] > 0):
            sum_pos += arr[j]
        else:
            sum_neg += arr[j]
print("sum of positive number : ",sum_pos)
print("sum of Negative number : ",sum_neg)

Input/Output:

Enter the size of the array: 5
Enter the Element of the array:
-30
78
54.6
25
-45.36
sum of positive number :  157.6
sum of Negative number :  -75.36
