Convert numeric to string

The sprintf function:

• Converts a numeric value
• To a C-style string
• According to a specified format, and
• Puts the individual characters
• Into an array of type char.

In Listing 5, the specified format (%d) is a signed decimal integer.

After the numeric value has been converted to a string in each case in Listing 5:

• The textout_ex function is called
• To display the string in a specified location in the window.

You learned about the textout_ex function in an earlier lesson.
