## Count Chars
### Objectives
1. Read input from the user until you get empty string
2. For each of the lines you read, count the number of characters and print it
### Constraints
1. You must use a while loop
2. Assume at least three lines of input
### Solution
```
#!/usr/bin/env bash
echo -n "Please insert your input: "
while read line; do
echo -n "$line" | wc -c
echo -n "Please insert your input: "
done
```
