Debug symbols typically include not only the name of a function or global variable, but also the name of the source code file in which the symbol occurs, as well as the line number at which it is defined Mismatch between the format specifiers and count and type of values results in undefined behavior and possibly program crash. Other information includes the type of the symbol (integer, float, function, exception, etc.), the scope (block scope or global scope), the size, and, for classes, the name of the class, and.

Winpdb debugging itself a debugger is a computer program used to test and debug other programs (the target programs)
Common features of debuggers include the ability to run or halt the target program using breakpoints, step through code line by line, and display or modify the contents of memory, cpu registers, and stack frames
The code to be examined might alternatively be running on an. Print debugging or tracing is the act of watching (live or recorded) trace statements, or print statements, that indicate the flow of execution of a process and the data progression Tracing can be done with specialized tools (like with gdb's trace) or by insertion of trace statements into the source code. Gdbserver is launched on the target system, with the arguments
Either a device name (to use a serial line) or a tcp hostname and port number, and the path and filename of the executable to be debugged it then waits passively for the host gdb to communicate with it Gdb is run on the host, with the arguments The path and filename of the executable (and any sources) on the host, and a device. The distribution includes the standard libraries for ada and c++ whose code is mostly written in those languages
An example call to the printf function printf is a c standard library function that formats text and writes it to standard output
