Practice Program






  • Program of Finding Element in an array.

    • Solution: 
    void main()
{
     int i,element,a[10],n;


     printf("\nEnter the number of element: ");
     scanf("%d",&n);

//taking array element as input from user.
     for(i=0;i<i++)
    {
        printf("\nEnter the element: ");
        scanf("%d",&a[i]);
    }
//printing array elements
        printf("\nArray Elements are: ");
       for(i=0;i<i++)
      {
         printf("%d\t",a[i]);
      }
//taking number which we have to find
    printf("\nEnter the number you want to find: ");
    scanf("%d",&element);

     
//finding element.
     for(i=0;i<i++)
     {
       if(element == a[i])
         printf("\nElement is found at %d Position",i+1);
     }
}

    Output1
    Enter the number of elements: 5

    Enter the Element: 1
    Enter the Element: 2
    Enter the Element: 3
    Enter the Element: 4
    Enter the Element: 5

    Array Elements
    5     4     3     2     1

    Enter the number you want to find: 4
    Element is found at 2 Position

    Output2
    Enter the number of elements: 10

    Enter the Element: 1
    Enter the Element: 2
    Enter the Element: 3
    Enter the Element: 4
    Enter the Element: 5
    Enter the Element: 6
    Enter the Element: 7
    Enter the Element: 8
    Enter the Element: 9
    Enter the Element: 10

    Array Element are :
    10     9     8     7     6     5     4     3     2     1

    Enter the number you want to find: 5
    Element is found at 6 Position

    Output3
    Enter the number of elements: 15

    Enter the Element:1
    Enter the Element:2
    Enter the Element: 3
    Enter the Element: 4
    Enter the Element:5
    Enter the Element: 6
    Enter the Element:7
    Enter the Element: 8
    Enter the Element: 9
    Enter the Element:10
    Enter the Element: 11
    Enter the Element: 12
    Enter the Element: 13
    Enter the Element: 14
    Enter the Element: 15

    Array Element are :
    15     14     13     12     11    10     9     8     7     6     5     4     3     2     1

    Enter the number you want to find: 10
    Element is found at 6 Position






    defining a function 'find_element' which will return position of the element. 

    int find_element(int a[],int n,int element)
{
    int i;

    for(i=0;i<i++)
    {
        if(element == a[i])
         return i;
    }


}

    Using above define function 'find_element()': 
    void main()
{
    int i,res,a[10] = {10,12,13,14,15,16,17,18};

    res = find_element(a,8,14);


    printf("Element is found at %d Position",res+1);
}

    Output1
    Element is found at 4 Position

    Using above define function 'find_element()': 
    void main()
{
    int i,res,a[10] = {21,22,23,24,25,26,27,28};

    res = find_element(a,8,25);


    printf("Element is found at %d Position",res+1);
}

    Output2
    Element is found at 5 Position

    Using above define function 'find_element()': 
    void main()
{
    int i,res,a[10] = {31,32,33,34,35,36,37,38};

    res = find_element(a,8,36);


    printf("Element is found at %d Position",res+1);
}

    Output3
    Element is found at 6 Position
