Conclusions

Try to prevent bugs by analysing the problem before and by designing good program structures. However, it is always possible that a program contains a number of bugs. To find these bugs the following methods exist:

• always be aware of the RTFM technique

• use the possibilities of warnings the compiler can give you

• using a debugging tool (ddd or gdb) is advisable above `printf() debugging'

• add assertions at critical places of your program

• use Electric Fence (or an other memory allocation debugging tool) to find problems with pointers and array bounds
