Here's an example of code that uses a loop to print all graphic characters in the ASCII character set:
In this code, a loop iterates through the ASCII character set from 0x21 to 0x7E. For each character, the isgraph() function is used to check if it is a graphic character. If it is, the character is printed to the screen. At the end, all the graphical characters in the ASCII table will be printed.
It's worth noting that this example uses the ASCII character set, which is widely used in many systems, but there are other character sets that are used in some systems. If you are working with a different character set, you may need to adjust the range of characters that you check.
