Sum of negative and positive integers of the array

Posted on Apr 23, 2020

C program to find sum of negative and positive integers of the array.

Program

#include<stdio.h>
#include<conio.h>
#define MAX 50

void main()
{
	int arr[MAX];
    int i, n, sum_neg, sum_pos;

    printf("Enter the number of elements in the array\t:");
    scanf("%d",&n);
    printf("Enter the elements\n");
    for(i=0;i<n;i++)
    {
        printf("Element %d\t:",i+1);
        scanf("%d",&arr[i]);
    }

    sum_neg = 0;
    sum_pos = 0;
    for(i=0;i<n;i++)
    {
        if(arr[i]>0)
            sum_pos = sum_pos + arr[i];
        else
            sum_neg = sum_neg + arr[i];
    }
    printf("\nSum of the positive elements of the array is\t:%d",sum_pos);
    printf("\nSum of the negative elements of the array is\t:%d",sum_neg);

    getch();
}

Output

Enter the number of elements in the array       :8
Enter the elements
Element 1       :1
Element 2       :-3
Element 3       :4
Element 4       :-5
Element 5       :9
Element 6       :-2
Element 7       :9
Element 8       :-4

Sum of the positive elements of the array is    :23
Sum of the negative elements of the array is    :-14
