c++ set element at index

To set an element at a specific index in C++, you can follow these steps:

1. Declare an array or a vector: Start by declaring an array or a vector that will hold the elements. For example, you can declare an array of integers like this:

int arr[5];

1. Assign values to the array: Assign values to the array elements using the assignment operator (=). For example, you can assign values to the array elements like this:

arr[0] = 10;
arr[1] = 20;
arr[2] = 30;
arr[3] = 40;
arr[4] = 50;

1. Set the element at the desired index: To set the element at a specific index, simply assign a new value to that index using the assignment operator. For example, to set the element at index 2 to 35, you can do the following:

arr[2] = 35;

1. Access the element at the desired index: If you want to access the element at the desired index after setting it, you can simply use the index operator ([]). For example, to access the element at index 2 after setting it to 35, you can do the following:

int element = arr[2];

Now, the variable element will contain the value 35.

That's it! By following these steps, you can set an element at a specific index in C++.
