Causes of and solutions for software crisis. 


Software engineering appears to be among the few options available to tackle the present software crisis. 

To explain the present software crisis in simple words, consider the following. The expenses that organizations all around the world are incurring on software purchases compared to those on hardware purchases have been showing a worrying trend over the years.





 Fig. 1.6: Change in the relative cost of hardware and software over time 




Organizations are spending larger and larger portions of their budget on software. Not only are the software products turning out to be more expensive than hardware, but they also present a host of other problems to the customers: software products are difficult to alter, debug, and enhance; use resources nonoptimally; often fail to meet the user requirements; are far from being reliable; frequently crash; and are often delivered late. Among these, the trend of increasing software costs is probably the most important symptom of the present software crisis. Remember that the cost we are talking of here is not on account of increased features, but due to ineffective development of the product characterized by inefficient resource usage, and time and cost over-runs.



There are many factors that have contributed to the making of the present software crisis. Factors are larger problem sizes, lack of adequate training in software engineering, increasing skill shortage, and low productivity improvements.

EXPLORATORY STYLE OF SOFTWARE DEVELOPMENT

EXPLORATORY STYLE OF SOFTWARE  DEVELOPMENT The exploratory program development style refers to an informal development style where the programmer makes use of his own intuition to develop a program rather than making use of his own institution to develop a program rather than making use of the systematic body of knowledge categorized under the software engineering discipline  . The exploratory development style gives the complete freedom to the programmer to choose the activities using which to develop the software. Though the exploratory style imposes no rules a typical development starts after an initial briefing from a customer. A schematic of this work sequence in a build and fixed style has been shown graphically below. An initial development style can be successful when used for developing very small programs, and not for professional software. What is wrong with exploratory style of software development ? * Though the exploratory software development style is int

STACK Programming in C

STACK Programming in C Language- Stack Data Structure Stack is a linear data structure which follows a particular order in which the operations are performed. The order may be LIFO(Last In First Out) or FILO(First In Last Out). There are many real-life examples of a stack. Consider an example of plates stacked over one another in the canteen. The plate which is at the top is the first one to be removed, i.e. the plate which has been placed at the bottommost position remains in the stack for the longest period of time. So, it can be simply seen to follow LIFO(Last In First Out)/FILO(First In Last Out) order. problem statement:perform the following operations -1.
