Write the code to produce a for loop that counts down from 20 to 0 by 2’s and prints the number each time it goes through the lo
yulyashka [42]

Explanation:

Count-controlled for loop (Three-expression for loop)

This is by far the most common type. This statement is the one used by C. The header of this kind of for loop consists of a three-parameter loop control expression. Generally it has the form:

for (A; Z; I)

A is the initialisation part, Z determines a termination expression and I is the counting expression, where the loop variable is incremented or dcremented. An example of this kind of loop is the for-loop of the programming language C:

for (i=0; i <= n; i++)

This kind of for loop is not implemented in Python!

Numeric Ranges

This kind of for loop is a simplification of the previous kind. It's a counting or enumerating loop. Starting with a start value and counting up to an end value, like for i = 1 to 100

Python doesn't use this either.

Vectorized for loops

They behave as if all iterations are executed in parallel. This means, for example, that all expressions on the right side of assignment statements get evaluated before the assignments.

Iterator-based for loop

Finally, we come to the one used by Python. This kind of a for loop iterates over an enumeration of a set of items. It is usually characterized by the use of an implicit or explicit iterator. In each iteration step a loop variable is set to a value in a sequence or other data collection. This kind of for loop is known in most Unix and Linux shells and it is the one which is implemented in Python.

Example of a simple for loop in Python:

>>> languages = ["C", "C++", "Perl", "Python"]  

>>> for x in languages:

...     print(x)

...  

C

C++

Perl

Python

Suppose a computer has 16-bit instructions. The instruction set consists of 32 different operations. All instructions have an op
Kazeer [188]

Answer:

2^7= 128

Explanation:

An instruction format characterizes the diverse part of a guidance. The fundamental segments of an instruction are opcode and operands. Here are the various terms identified with guidance design:  Instruction set size tells the absolute number of guidelines characterized in the processor.  Opcode size is the quantity of bits involved by the opcode which is determined by taking log of guidance set size.  Operand size is the quantity of bits involved by the operand.  Guidance size is determined as total of bits involved by opcode and operands.

Find the number of ideal integers within the given segment [low,high] inclusive. An ideal number is a positive integer that has
Alex Ar [27]

Answer:

  1. low = 10
  2. high = 50
  3. count = 0
  4. for i in range(low, high + 1):
  5.    if(i % 3 == 0 and i % 5 == 0):
  6.        count += 1
  7. print(count)

Explanation:

The solution code is written in Python.

We can create low and high variables to store the lower bound and upper bound in the range (Line 1-2)

Next create a counter variable, count (Line 3).

Use a for loop to traverse through the number between lower bound and upper bound and check if the current number-i is divisible by 3 and by 5, increment the count by one.

After the loop, print the count and we can get the number of ideal integers within the range (Line 8).

Paul [167]
<span>The answer is algorithm, because computer programmers need a programming language that's more similar to their native language. They then write specific steps a computer must take to complete the task at hand. Machine code is not easily memorized and is foreign to most people.</span>
