# Program to find how many 1's are present in an inputted array

by Dinesh Thakur Category: array

Algorithm for Ones Present Inputted Array:

step 1: set arr_size,j, count as three static variables of integer type

step 3: create an integer array arr[] of size arr_size

step 4: initialize i=0

step 5: repeat through step-7 while i less than arr_size

step 7: i=i+ 1

step 8: initialize i=0

step 9: repeat through step-15 while i less than arr_size

step 10: j=arr[i]

step 11: repeat through step-14 while j greater than 0

step 12: k=j%10

step 13: if k equals to one then count=count+ 1

step 14:j=j/10

step 15: i=i+ 1

step 16: print count

step 17: Exit

Here is the Java Example for Ones Present Inputted Array:

```import java.util.Scanner; public class OnesPresentInputtedArray {               public static int size;               public static int j;               public static int count;            public static void main(String args[])       {               Scanner s=new Scanner(System.in);               System.out.print("Enter the Number of Elements :");               size=s.nextInt();               int arr[]=new int[size];               System.out.println("Enter the Elements : ");               for(int i=0;i<size;i++)                  {                      System.out.println("Enter the "+i+"th Index Value");                      arr[i]=s.nextInt();                   }                      for(int i=0;i<size;i++)                         {                            j=arr[i];                            while(j>0)                               {                                  int k=j%10;                                    if(k==1)                                      {                                          count++;                                       }                                           j=j/10;                                }                          } System.out.print("No. of 1's Present in the Inputed Array is:-> "); System.out.println(count);       } }
