%x and %o in C language

In C language, "%x" and "%o" are format specifiers used in format strings. Used to specify how to print integers:

  • %x: Print an unsigned hexadecimal integer.
  • %o: Print an unsigned octal integer.

Usage:

To print an integer in hexadecimal or octal format, you need to use formatting functions such as printf() or sprintf() . The format specifier is placed before the variable to be printed. For example:

<code class="c">int number = 123;
printf("十六进制:%x\n", number);
printf("八进制:%o\n", number);</code>
Copy after login

Output:

Running the above code will output:

<code>十六进制:7b
八进制:173</code>
Copy after login

Note:

  • Unsigned integers are represented as non-negative numbers.
  • Hexadecimal numbers are represented using 0-9 and a-f (or A-F).
  • Octal numbers are represented using 0-7.
