Write With Line Numbers

Task

Implement the function write_with_line_numbers

• Given a file path and a string, write the string out to the file with line numbers at the beginning of each line
• So a string like "joe: hello\nolivia: yo\njoey: sup" would be written as

1 joe: hello
2 olivia: yo
3 joey: sup

IMPORTANT

The input strings to test with have a slash and n ('\n'), not an actual newline character. Do not have to process the string literal ('\n') in function, this is processed for you in convert_escaped_newlines. In your function write_with_line_numbers, treat the '\n' from the input string as an actual newline char

• Do not print anything inside of the write_with_line_numbers function, this is handled in the main function

Function Signature

// Given a file path and a string, write the string out to the file with line numbers
// at the beginning of each line
//
// For example:
// Input: "output.txt joe: hello\nolivia: yo\njoey: sup"
//        (path = "output.txt", to_save = "joe: hello\nolivia: yo\njoey: sup")
//
// Output (in output.txt):
// 1 joe: hello  
// 2 olivia: yo  
// 3 joey: sup
//
//

Example

$ gcc write_with_line_numbers.c -o write_with_line_numbers
$ ./write_with_line_numbers
output.txt joe: hello\nolivia: yo\njoey: sup
$ cat output.txt 
1 joe: hello
2 olivia: yo
3 joey: sup
$ ./write_with_line_numbers < input.txt (saves result to result.txt)
$ cat result.txt 
1 A very long line of text. A very long line of text. A very long line of text.
2 Another long one here
3 And a third long one
4 More lines to test this function correctly
5 This is line number five without numbering in the text
6 Sixth line continues the example nicely
7 Seventh line here with more words to fill the space
8 Eighth line is also quite verbose and descriptive
9 Ninth line is getting close to the end
10 Tenth line finishes the first half nicely
