Click ‘Get Form’ to open the Characters and Strings document in the editor.
Begin by identifying character constants. Enter a single character surrounded by single quotes, such as 'A' or '?'. Remember that these represent integer values.
For special characters, use the backslash followed by the appropriate character (e.g., \n for newline). Ensure you include any necessary escape sequences.
Next, focus on string constants. Input a sequence of characters enclosed in double quotes, like "ABC". If your string includes special characters, remember to escape them with a backslash.
When declaring strings, ensure you account for the NULL character at the end. For example, inputting "ABC" will actually store four bytes: 'A', 'B', 'C', and '\0'.
Finally, review your entries for accuracy before saving or exporting your completed form.
