 #### Concatenate: `strcat`
 `strcat` (from 'string concatenate') will concatenate a string, meaning it will take the contents of one string and place it on the end of another string. In this example, the contents of `second` will be concatenated onto `first`:
 ```C
 strcat(first, second);
 ```

+#### Get length: `strlen`

 `strlen` (from 'string length') will return an integer value corresponding to the length of the string. In this example, an integer called `string_length` will be assigned the length of `my_string`:
 ```C
 string_length = strlen(my_string);
