Which of the following is NOT true about variables?

VikaD [51]

Answer:

The answer to this question is given below in the explanation section.

Explanation:

The value stored by a variable can be changed after it is assigned(true).

The value of a variable can be changed after it is assigned, for example:

int a=10;

and we can change the value of variable a in letter program such as:

a=15;

Variables are a name for a spot in the computer's memory (true).

it is true, because the variables value stored in the computer's memory and we can access theses values by their name (variable name). so Variables are a name for a spot in the computer's memory.

Variable names can be words: such as temperature or height (true).

Yes, the variable name can be words such as height, width, temperature etc.

The value stored by a variable cannot be changed after it is assigned (false).

It is noted that the value stored by a variable can be changed after it is assigned. However, it is noted that is some programming language, you can't change the value of static variable.

Given input characters for an arrowhead and arrow body, print a right-facing arrow. Ex: If the input is: *

MrRa [10]

Answer:

Following are the code to this question:

b= input()#defining b variable for input character value

h= input()#defining h variable for input character value

b_width=6#defining b_width variable that holds an integer value 6

r1 = ' ' * b_width+h#defining r1 variable that calculates hash lines

r2 = b*b_width+h*2#defining r3 variable that calculates 6 asterisk and 2 hash line

r3 = b*b_width+h*3#defining r3 variable that calculates 6 asterisk and 3 hash line

print(r1)#print r1 variable value

print(r2)#print r2 variable value

print(r3)#print r3 variable value

print(r2)#print r2 variable value

print(r1)#print r1 variable value

Output:

please find the attachment.

Explanation:

In the given python code, three variable "b,h, and b_width" is declared, in which "b_width" holds an integer variable "6" and variable "b and h" is used to an input character value. In the next line, "r1, r2, and r3" is declared, that holds arrowhead values which can be defined as follows:

In the "r1" variable, it stores space with b_width variable and one h variable value.
In the "r2" variable it stores b_width and 2*h variable value.
In the "r3" variable it stores b_width and 3*h variable value.

At the last, it prints the "r1, r2, and r3" variable value and for arrowheads, it follows the above program code.
