# C++ Program to Determine the Unicode Code Point at a Given Index

• Last Updated : 07 Oct, 2022

Here, we will find out the unicode code point at a given index using a C++ program.

Input:

`arr = "geEKs"`

Output:

```The Unicode Code Point At 0 is = 71.
The Unicode Code Point At 1 is = 101.
The Unicode Code Point At 2 is = 69.
The Unicode Code Point At 3 is = 107.
The Unicode Code Point At 4 is = 83.```

## Approach:

If the array/string value is increased then it is not feasible to declare an individual variable for the index. If the string size is decreased then the fixed variables can give Out of Bound Error. To handle these situations we will use a for loop to traverse the given string and print the corresponding code point.

Example:

## C++

 `// C++ program to demonstrate` `// Unicode Code point` `// at a given index` `#include ` `using` `namespace` `std;`   `// Driver code` `int` `main()` `{` `    ``// define input array/string` `    ``char` `arr[] = ``"GeEkS"``;` `    ``int` `code;`   `    ``// print arr` `    ``cout << ``" Input String = "` `<< arr;`   `    ``// execute a loop to traverse the arr elements` `    ``for` `(``int` `i = 0; arr[i] != ``'\0'``; i++) {` `        ``code = arr[i];`   `   ``// display unicode code point at i-th index` `   ``cout <<``"\n The Unicode Code Point At "``<

Output

``` Input String = GeEkS
The Unicode Code Point At 0 is 71
The Unicode Code Point At 1 is 101
The Unicode Code Point At 2 is 69
The Unicode Code Point At 3 is 107
The Unicode Code Point At 4 is 83```

Time Complexity: O(n), where n is the array size.
Space Complexity: O(1),
