Separate out +ve, -ve and 0 array elements - C Program

Write a C program to store N integer element in an array and then separate all positive, negative and zeros in three different arrays.

Solution:

In mathematics integer have all positive, negative number including zero. In this program we will just separate all positive, negative and zero using loop and condition statement.

Program

#include<conio.h>
#include<stdio.h>
#define max 100
void seperate(int[],int);
void main()
{
     int a[max],i,n;
     printf("Enter the limit of array: ");
     scanf("%d",&n);
     printf("Enter the elements: ");
     for(i=0;i<n;i++)
     {
         scanf("%d",&a[i]);
     }
     seperate(a,n);
     getch();
}
void seperate(int a[max],int l)
{
     int p[max],x=-1,n[max],y=-1,z[max],w=-1,i=0;
     for(i=0;i<l;i++)
     {
          if(a[i]>0)
          {
               x++;
               p[x]=a[i];
          }
          else
          {
               if(a[i]<0)
               {
                    y++;
                    n[y]=a[i];
               }
               else
               {
                    w++;
                    z[w]=a[i];
               }
           }
      }

      if(x>=0)
      {
           printf("\nThe positive array is: ");
           for(i=0;i<x+1;i++)
           {
                printf("%d ",p[i]);
           }
      }
      else
      {
            printf("\nArray is not have any positive value");
      }

      if(y>=0)
      {
            printf("\nThe negative array is: ");
            for(i=0;i<y+1;i++)
            {
                 printf("%d ",n[i]);
            }
       }
       else
       {
             printf("\nArray does not have any negative value");
       }

      if(w>=0)
      {
            printf("\nThe zeros in array is: ");
            for(i=0;i<w+1;i++)
            {
                 printf("%d ",z[i]);
            }
      }
      else
      {
            printf("\nArray does not have any zeros value");
      }
}


Output:

positive negative number
