Posted on Apr 23, 2020

C program to count positive and negative numbers in an array.

Program

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

void main()
{
	int arr[MAX];
    int i, n;
    int count_pos, count_neg;

    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]);
    }

    count_pos = 0;
    count_neg = 0;
    for(i=0;i<n;i++)
    {
        if(arr[i]>=0)
        {
            count_pos++;
        }
        else
        {
            count_neg++;
        }
    }
    printf("\nTotal count of positive numbers\t:%d",count_pos);
    printf("\nTotal count of negative numbers\t:%d",count_neg);

    getch();	
}

Output

Enter the number of elements in the array       :8
Enter the elements
Element 1       :4
Element 2       :5
Element 3       :-5
Element 4       :-8
Element 5       :7
Element 6       :0
Element 7       :6
Element 8       :-3

Total count of positive numbers :5
Total count of negative numbers :3
