Search an element in an array with C.


#include <stdio.h>

int main()
{
    int arr[100];
    int size, i, toSearch, found;

    /* Input size of array */
    printf("Enter size of array: ");
    scanf("%d", &size);

    /* Input elements of array */
    printf("Enter elements in array: ");
    for (i = 0; i < size; i++)
    {
        scanf("%d", &arr[i]);
    }

    printf("\nEnter element to search: ");
    scanf("%d", &toSearch);
    found = 0;

    for (i = 0; i < size; i++)
    {
 
        if (arr[i] == toSearch)
        {
            found = 1;
            break;
        }
    }
    if (found == 1)
    {
        printf("\n%d is found at position %d", toSearch, i + 1);
    }
    else
    {
        printf("\n%d is not found in the array", toSearch);
    }

    return 0;
}

Output

Enter size of array : 5
Enter elements in array : 1 2 3 4 5

Enter element to search : 4

4 is found at position 4
