Question
Transcribed Image Text:Find the output of the function call `my_func("Hello")` where the definition of `my_func()` is given below:
```cpp
string my_func(string s){
string r = s;
reverse(s.begin(), s.end());
return r+s;
}
```
### Explanation:
This function takes a string `s` as input. It first assigns the value of `s` to another string `r`. Then, it reverses the string `s`. Finally, it returns the concatenation (`r+s`) of the original string `r` and the reversed string `s`.
The output of `my_func("Hello")` will be the original string concatenated with its reverse, resulting in "HelloolleH".

Function specifications: Name: split() Parameters (Your function should accept these parameters IN THIS ORDER): input_string string: The text string containing data separated by a delimiter separator char: The delimiter marking the location where the string should be split up arr string array: The array that will be used to store the input text string's individual string pieces arr_size int: The number of elements that can be stored in the array Return Value: int: The number of pieces the input text string was split into Note: No input will have delimiters in the beginning or the end of the string.

- write a code in C++ You work for a streaming analytics company and have been tasked with writing a program that analyzes views and likes on a series of YouTube videos. Code a modular program that uses parallel arrays to store views, likes, and like percentages for a series of videos. The program must do the following: The program must first ask the user for the number of videos that will be selected from YouTube. This must be done using a function that is called. For each video, the program must use random numbers to generate the number of views, likes, and the like percentage and store each value in a series of parallel arrays. These arrays must NOT be declared globally. These arrays also must be populated using a loop that calls a series of functions to generate the views, likes, and like percentage. The following arrays must be declared: views[] - an array of type long to hold the randomly generated views each YouTube video gets likes[] - an array of type long to hold the…arrow_forwardASSIGNMENT: Write a program to use the capability of Recursion to calculate factorials.
