How do you print the last element of an array?

The steps involved to get the last element of an array are:

1. Use array slice() to return a specific element.
2. Retrieve the last element using negative index array. slice(-1)
3. Save the last element in a variable.

What is the last element of array in C?

To access the elements of an array, you must use array notation. The first element of an array is at position 0, the second at position 1, etc. The last element of an array is at position size – 1.

What is the last element of an array?

The Last element is nothing but the element at the index position that is the length of the array minus-1. If the length is 4 then the last element is arr[3].

How do you print the first and last elements of an array?

Operator[] requires an index and it returns reference to that index, thus, to get the first element of an array, we use 0 as an index (as we know that array index starts with 0) and to get the last element, we use array::size() function it returns the total number of elements, thus, to get the last element of an array.

How do I print a single element in an array?

You can access an array element using an expression which contains the name of the array followed by the index of the required element in square brackets. To print it simply pass this method to the println() method.

How do you return the last element in an array C++?

C++ Array Library – back() Function The C++ function std::array::back() Returns a reference to the last element of the array container. This method returns last array element itself, calling this method on empty array container will cause undefined behavior.

How do you call the last element of an array in C++?

To get the last element (50) from the array, we can use the std::array::back() function in C++. The std::array::back() function is defined inside the array. h header file. Similarly, we can also get the last element of an array by using the subscript operator [] with last element index.

What is the last element in the periodic table?

oganesson
Element 118, the final element in our International Year of the Periodic Table series, is oganesson. Oganesson was discovered in 2002 and its properties defy our expectations based on trends in the periodic table. Oganesson has several distinctions amongst all of the elements in the periodic table.

How do I print the first element and the last element then the second and second last element of an array in C?

Run a loop from beginning and ending of the array till you meet in the middle. This will print start_index first then end_index element. Then it will increase the start index and decrease the end index . Again it will print second element and second last element and so on.

Can you print arrays in C?

We need to declare & define one array and then loop upto the length of array. At each iteration we shall print one index value of array. We can take this index value from the iteration itself.

How do you print a string array without loop?

This article tells how to print this array in Java without the use of any loop. For this, we will use toString() method of Arrays class in the util package of Java. This method helps us to get the String representation of the array. This string can be easily printed with the help of print() or println() method.

How do you print an array backwards in C++?

Algorithm to reverse an array

1. First of all take number of elements as input from user. Let it be N.
2. Then ask user to enter N numbers and store it in an array(lets call it inputArray).
3. Declare another array of size equal to input array.
4. Using a for loop, copy elements from inputArray to reverseArray in reverse order.

How to get first and last element from array in C++?

Get first and last elements from Array and Vector in CPP. Given an array, find first and last elements of it. Input: {4, 5, 7, 13, 25, 65, 98} Output: First element: 4 Last element: 98. In C++, we can use sizeof operator to find number of elements in an array. // C++ Program to print first and last element in an array.

How to get the last index of an array in C?

If you have an actual array and not a pointer, the number of elements in the array could be calculated by using sizeof array / sizeof array [0]. From that you can get the last index.

How to print the size of an array in Python?

Lets have an array int array a [50] = {1,2,3,4} (The other elements are initialised to zero on partial init) If you know the size of the array, printing it is straightforward. int size = sizeof (array)/sizeof (int) // use data type instead of int depending on array.

How to find number of elements in an array in C++?

In C++, we can use sizeof operator to find number of elements in an array. We should not sizeof when arrays are passed as parameter s, there we must pass size and use that size to find first and last elements.
