TITLE: Array in C++

AIM:

   i) To write a program to search for an element in an array.
   ii) To write a program to declare a matrix in an array and print. 
   iii) To write a program to add a matrix using array. 

THEORY: In C++, an array is a collection of elements of the same data type stored in contiguous memory locations. Each element in the array can be accessed using an index, which starts from 0 for the first element and goes up to the size of the array minus one. C++ arrays have fixed sizes determined at compile time. If you need a dynamic-sized container, consider using other data structures like std::vector or dynamic memory allocation with pointers.

ALGORITHM:

        1. Start
        2. Declare variables: arr[10] (array to store elements), I, num (element to search),
        n (array size), cnt (counter for an element found), pos (position of element found).
        3. Display "Enter Array Size:".
        4. Read the value of 'n' (array size).
        5. Display "Enter Array Elements:".
        6. Loop 'i' from 0 to 'n-1':
           a. Read and store arr[i] from the user.
        7. Display "Enter element to be searched:".
        8. Read the value of 'num' (element to search).
        9. Loop 'i' from 0 to 'n-1':
           a. If arr[i] is equal to 'num':
           i. Set cnt to 1 (element found).
          ii. Set pos to i+1 (position of the element).
          iii. Break the loop.
        10. If cnt is 0:
            a. Display "Element Not Found!!".
        11. Else:
              a. Display "Element <num> Found at position <pos>".
        12. End

CONCLUSION: An element in the array is searched and the program is executed successfully. A matrix is printed using array. Two matrices are added using an array.
