Chapter 1, Problem 20RQ

Explanation of Solution

Two programming language deficiencies:

Early 1970s witnessed a major change in the computing industry. The main focus shifted from hardware to software as the cost of hardware went down while the cost of programmers started to increase. This shift made researchers to focus on the area of software development. More and more fields started to use complex programs. Earlier, computers programs were used only for fairly simple problems such as solving some equations to simulate the path of a satellite and others. But with increasing use of computer systems need for complex programs emerged. Now, the computer programs were being used for complex applications such, international airline bookings, control of whole nuclear reactors...
