The two clues that a tester can take from the code when writing tests are:
Always write tests before the code needed to pass them.The test prepares for the code's intended behavior.What do code tests do?In order to find flaws or problems throughout the software development process, code-based testing requires running over every line of code in a program.
The program is tested against specific test cases to determine whether it executes the necessary functionalities. Static and structural testing are two further subcategories of code-based testing.
Therefore, the evidence that a tester can use in a program if they are writing some kinds of codes are those based on the code written.

Assume that x, y, and z are int variables. Write a statement using the conditional operator (? :) that compares the values of the variables x and y. The value of the larger of the two variables should be assigned to z.
The statement using the conditional operator (? :) that compares the values of the variables x and y will be:
public class Main {
public static void main(String[] args) {
int x = 10;
int y = 20;
int z = (x > y) ? x : y;
System.out.println("z = " + z);
}
}
How to illustrate the information?The ternary conditional operator (?:) has three operands and accepts them all. A boolean expression that can be evaluated as true or false makes up the first operand. The second operand is executed if the boolean statement evaluates to true. The third operand is executed if the boolean expression returns false.
It should be noted that because 10 is not greater than 20, the boolean statement (x > y) in this program evaluates to false. As a result, the third operand (y) is executed, and z is given the value of y (20).

Answer:
z = (x > y) ? x : y;
Explanation:
The conditional operator in C++ is the "? :" operator. This operator checks a condition and then returns one of two values, depending on whether the condition is true or false. The syntax for the conditional operator is:
(condition) ? value_if_true : value_if_false;
z = (x > y) ? x : y; checks if the value of x is greater than y. If it is, then the value of x is assigned to z. If it is not, then the value of y is assigned to z.

List all the tests that you would do in order to test the
isosceles function that receives as parameter the length of
the three sides of one triangle (integer numbers) and returns
one Boolean (true when the triangle is isosceles and false

triangle because of the lengths of the sides).
Test case example: islsosceles (3,2,3)--> TRUE. Keep the

What is the purpose of a frame check sequence (FCS) footer?
Answer:
Frame check sequence (FCS) refers to the extra bits and characters added to data packets for error detection and control.
Explanation:
Network data is transmitted in frames. Each frame is comprised of bits of data appended to the header, which holds basic information such as source and destination media access control (MAC) addresses and application. Another set of characters is added to the end of the frames, which are checked at the destination. Matching FCSs indicate that delivered data is correct.

Even though the terms operating memory and short-term memory are frequently used interchangeably, some theorists contend that the two memory types are distinct from one another because working memory permits the manipulation of information.
What system storage working memory to function properly?In contrast to long-term memory, which stores a large amount of knowledge over a lifetime, working memory is the little amount of information that may be kept in mind and used to carry out cognitive tasks. One of the most often used concepts in psychology is working memory.
Working memory is the short-term storage of information, in contrast to long-term memory, which accumulates a huge quantity of information throughout a lifetime. That has been stored, while short-term memory only refers to the temporary storing of information.

in python Simple geometry can compute the height of an object from the object's shadow length and shadow angle using the formula: tan(angleElevation) = treeHeight / shadowLength. Given the shadow length and angle of elevation, compute the tree height.
Sample output with inputs: 0.4 17.5
Tree height: 7.398881327917831
Answer:
import math
angle = float(input('Enter Angle: '))
shadowLength = float5(input('Enter Shadow Length: '))
tree_height = math.tan(angle)*shadowLength
print('Tree Height = {}'.format(tree_height))
Explanation:
From the equation given, the first step is to derive the equation for calculating the Tree Height.
In order to calculate the tangent of an angle, the math module has to be imported. math module allows the program to perform advanced math operations.
The program then prompts the user to input values for angle and shadow length.
The inputted values are converted to floats and used in the equation that was derived for Tree height.
