Explanation:The Challenge of Cost control is a major challenge affecting the software engineering in the 21st century,the cost of Microchips and other hardware are constantly rising.

The challenge of competence is another major challenge affecting software engineering in the 21st century,as most software engineers lack the required competence to handle some of the issues facing softwares.

The challenge of reduced system delivery times is a major challenge likely to affect software engineering in the 21st century,as people required the software to be available in the shortest possible time.

Consider the following two code segments, which are both intended to determine the longest of the three strings "pea", "pear", a
Nikolay [14]

Answer:

e) Code segment II produces correct output for all values of str, but code segment I produces correct output only for values of str that contain "pea" but not "pear".

Explanation:

<em>if - elseif - else statements work in sequence in which they are written. </em>

  • <em> </em>In case <em>if() statement is true, </em>else if() and else statements will not get executed.
  • In case <em>else if() statement is true</em>, conditions in if() and else if() will be checked and else statement will not be executed.
  • In case <em>if() and else if() both are false</em>, else statement will be executed<em>.</em>

First, let us consider code segment I.

In this, first of all "pea" is checked in if() statement which will look for "pea" only in the String str. So, even if "pearl" or "pear" or "pea" is present in 'str' the result will be true and "pea" will get printed always.

After that there are else if() and else statements which will not get executed because if() statement was already true. As a result else if() and else statements will be skipped.

Now, let us consider code segment II.

In this, "pearl" is checked in if() condition, so it will result in desired output.

Executable code is attached hereby.

Correct option is (e).
