Output Formats (Debugging with GDB)By default, GDB prints a value according to its data type Sometimes this is not what you want For example, you might want to print a number in hex, or a pointer in decimal Or you might want to view data in memory at a certain address as a character string or as an instruction To do these things, specify an output format when you print a value
- Debugging with GDB - Examining Data
GDB prints memory addresses showing the location of stack traces, structure values, pointer values, breakpoints, and so forth, even when it also displays the contents of those addresses The default is on For example, this is what a stack frame display looks like, with set print address on:

For example, you might want to print a number in hex, or a pointer in decimal Or you might want to view data in memory at a certain address as a character string or as an instruction To do these things, specify an output format when you print a value The simplest use of output formats is to say how to print a value already computed

The most common example of it is *argv@argc Format If specified, allows overriding the output format used by the command Valid format specifiers are: o - octal x - hexadecimal u - unsigned decimal t - binary f - floating point a - address c - char s - string Examples

Output Formats (Debugging with GDB)Print using the ‘ raw ’ formatting By default, GDB will use a Python-based pretty-printer, if one is available (see Pretty Printing) This typically results in a higher-level display of the value’s contents The ‘ r ’ format bypasses any Python pretty-printer which might exist For example, to print the program counter in hex (see Registers), type
- How can the result of print-like formatting be used in a gdb . . .
Using GDB's Python extension, you can run any GDB command and put its output into a convenience variable, whose type will be an array of characters You can then use this convenience variable in a printf command with the %s format

GDB, the acronym for GNU Debugger, is a powerful debugging tool used to analyze and debug programs written in languages like C, C++, Ada, and Fortran It allows developers to inspect the behavior of their programs, step through code, set breakpoints, and examine variable values in real-time
