Abstract:Faults in software document can really affect the entire behavior of the software. Many types of faults exist in the software code document after its development. Software becomes less reliable if these faults are not removed from it.  A proper knowledge of the various types of software errors and a good classification of these errors are required before implementing any techniques related to their correction or detection. Manual inspection of the code document is also possible but disadvantage of this technique is, it requires too much time and manpower. So employing large teams for inspection of code is very costly. Thus, correction and automatic detection of these software errors, with the lack of automated tools, are vital to easing the maintenance of software. Most of the techniques available today only focus on the detection of fault, so in order to remove these faults in significant and reliable way is a challenging task. So many techniques are available for detection and corrections. This paper discusses these techniques.
