Answer:

Implicit type casting means the type casting done by the compiler during compilation of program whereas Explicit type casting means the programmer explicitly type casts the variables. This is the difference implicit and explicit type casting.

Explanation:

Type casting means the conversion of one data type into another data type. There are two types of type casting. They are Implicit type casting and Explicit type casting.

<u>Implicit type casting:</u> The type casting which is done by the compiler during the compilation of a program. This occurs when we assigning smaller data type to larger data type and also both the data type are compatible. Below example clears the above concepts.

Ex: $int \, i = 10;$

$long \, l = i;$

In the above example " i " is " int " data type whereas " l " is long data type but as we assigned the value of " i " to " l ". Here " int " and " long " are compatible data types and we assigned smaller data type ( int - i ) to larger data type ( long - l ) implicit type casting occurs.

<u>Explicit type casting:</u> The type casting which is done by the programmer explicitly to convert one data type into other data type. If we want to assign a value of larger data type to smaller data type explicit type casting is required. Below example clears the above concepts.

Ex: $double \, d = 10.4;$

$long\, l = (long) d;$

In the above example " d " is " double " data type whereas " l " is " long " data type. Here we are explicitly type casting to change larger data value ( double - d ) to smaller data value ( long - l ).

.Answer: When one data type is converted to another data type it is called typecasting. Typecasting can be both implicit and explicit.

Implicit typecasting is done by the compiler without the involvement of the programmer. However, explicit typecasting is done by the programmer whereby it asks the compiler to make the desirable data type changes.

Explanation:

Examples of implicit typecasting are:

int a = 2;

float b= 3.14;

Here, the compiler can make the desired changes.

Examples of explicit typecasting :

double a = 4;

int b = (int)a;

Here, the programmer is explicitly asking the compiler to make the changes in the data type.

Which technology can allow a single ground-based telescope to achieve images as sharp as those from the Hubble Space Telescope?

Ganezh [65]

Answer:

The correct answer to the following question will be "Adaptive Optics".

Explanation:

AO (Adaptive Optics) is a technique used to enhance optical system performance by reducing the impact of incoming gravitational wave distortions by compressing a mirror to compensate for the distortion.
It operates by calculating and compensating for defects in a wave-front with a system that corrects these errors as a deformable mirror or even a liquid crystal collection.

It is a technique that can make it possible for a single ground-based telescope to get images as clear as that of the Hubble Space Telescope.

Certain methods can achieve power resolution that exceeds the limit set by atmospheric distortion, for example, Aperture synthesis, Lucky imaging, and Speckle imaging.

Therefore, Adaptive Optics is the right answer.

a. displays the sum of all even numbers between 2 and 100 (inclusive). b. displays the sum of all squares between 1 and 100 (inc

LuckyWell [14K]

Answer:

The program required is in the explanation segment.

Explanation:

Program :

import math

# a. displays the sum of all even numbers between 2 and 100 (inclusive).

print("All even numbers from 2 to 100 inclusive ")

sum=0

i=2

while i<=100:

if i %2 ==0:

sum=sum+i

print(i,end=" ")

i=i+1

print("\nThe sum of all even numbers between 2 and 100 (inclusive) :",sum);

#b. displays the sum of all squares between 1 and 100 (inclusive).

print("\nAll squares numbers from 1 to 100 inclusive:")

i=1

sum=0

while i<=100:

print(i*i,end=" ")

i=i+1

sum=sum+(i*i)

print("\n\nThe sum of all squares between 1 and 100 (inclusive) is :",sum)

#c. displays the powers of 2 from 1 up to 256.

print("\nAll powers of 2 from 2 ** 0 to 2 ** 8:")

i=0

while True:

p=math.pow(2,i)

if p>256:

break

print("2 ** ",i," is ",int(p))

i=i+1

#d. displays the sum of all odd numbers between a and b (inclusive), where a and b are inputs

print("\nCompute the sum of all odd integers between two intgers ")

a=int(input("Enter an integer:"))

b=int(input("Enter another integer: "))

count = 0

temp=a

sum=0

while a<=b:

if a%2!=0:

print(a,end=" ")

sum=sum+a

a=a+1

print("\nThe total of the odd numbers from ", temp ," to ", b ,"is",sum)

#e.displays the sum of all odd digits of an input. (For example, if the input is 32677, the sum would be 3 + 7 + 7 = 17.)

print("\nCompute the sum of the odd digits in an integer ")

n=int(input("Enter an integer:"))

count=0

sum=0

temp=n

while n!=0:

rem = n%10

if rem%2!=0:

sum=sum+rem

count=count+1

n=int(n/10)

print("Sum of the odd digits is ",sum)

print("The total of the odd digits in ",temp," is ",count)

almond37 [142]

(Disclaimer: I am not a professional, so it might not be the most concise answer possible, but I did run the Python script and it works)

Answer:

user_input = input("What food do you have in your refrigerator? ").lower()

count = 0

while True:

if user_input != 'apples':

count += 1

print(f'You have a {user_input} with a total of {count} food(s)\n')

user_input = input("What food do you have in your refrigerator? ")

else:

break
