Answer:
1. When calculating the division of each number in some range of floating type number.
2. One cannot use real numbers for exact comparison. Two real numbers are rarely equal. Real numbers are have representational errors.
Explanation:
1. In structured programming, we make use of a floating-point number with a fractional part for a loop control variable. a given scenario is when we just want to calculate the division of each number in some range of floating type number. However, the downsides to using a floating-point number with a fractional part for a loop control variable are:
- They can cause 'off-by-one' failure
- A floating point number cannot represent all simple fractions exactly
2. The pitfalls of using real numbers for the index variable in a for loop:
- Two real numbers are hardly equal
- One cannot use real numbers for exact comparison
- The existence of representational errors
Imagine going around a database or your folders on your hard drive in a text based only environment. This is a task normally done by the technical user. A GUI allows you to use pictures and icons (or other images) in order to make sense of what is going on. Some programs or Operating Systems may use text that wouldn't make sense to the average/basic user so using images to represent the task it is you are doing makes things a whole lot simpler. Not only that but using a GUI allows you to make a organized environment that a user can be familiar with. its kind of like a standard that isn't necessarily a rule.<span />
Pattern recognition is part of "Machine Learning" which is a computer science concept of teaching the program to adapt.
What kind of pattern are you looking to recognise? Do you want to code it yourself? What language are you programming in?

Check the explanation
Explanation:
The above question can be sovled in the below step by step way:
15 can be written as 16-1 = 24 -1
Therefore, 15 *13 = (24 -1)*13
= 13*24 - 13
Now, when we left shift a number we multiply it by 2k .Where k is no of times we left shifted it.
Therefore, 13*24 = shift 13 to left 4 times
15 * 13 = shift 13 to left 4 times and subtract 13 from it.
Packet analyzer is a tool that captures every packet transmitted over a network and analyzes the content. Basically this is used to gather network statistics and troubleshoot network issues.
