Answer:

Relational query language is the language that is used in the queries of the relational databases that has rows and columns in table. The user or client presents a request for gaining the information from the database. The relationships in the database are defined in numerous ways which creates the query.

This language can be procedural form or non-procedural form.The operations performed by this language are communication with the relational database, analyzing the relationships between the entities of database,splitting the request from client and then execution of that request is done by database management system(DBMS), etc.

Sloan [31]

Answer:

In Python:

def  Pythagorean_triple(hyp,side1,side2):

   if hyp**2 == side1**2 + side2*2:

       return True

   else:

       return False

               

print("Hypotenuse\tSide 1\t Side 2\t Return Value")

for i in range(1,501):

   for j in range(1,501):

       for k in range(1,501):

           print(str(i)+"\t"+str(j)+"\t"+str(k)+"\t"+str(Pythagorean_triple(i,j,k)))

Explanation:

This defines the function

def  Pythagorean_triple(hyp,side1,side2):

This checks for pythagorean triple

   if hyp**2 == side1**2 + side2*2:

Returns True, if true

       return True

   else:

Returns False, if otherwise

       return False

               

The main method begins

This prints the header

print("Hypotenuse\tSide 1\t Side 2\t Return Value")

The following is a triple-nested loop [Each of the loop is from 1 to 500]

for i in range(1,501): -->The hypotenuse

   for j in range(1,501): -->Side 1

       for k in range(1,501):-->Side 2

This calls the function and prints the required output i.e. the sides of the triangle and True or False

           print(str(i)+"\t"+str(j)+"\t"+str(k)+"\t"+str(Pythagorean_triple(i,j,k)))

Consider the code fragment below (with nested loops). int sum = 0;for (int i = 1; i < 5; i++) for (int j = 1; j <= i; j++)
sammy [17]

Answer:

Option d is the correct answer for the above question.

Explanation:

  • The first loop of the program has a second loop and then the statement. In this scenario, the second loop executes for the value of the first loop and the statement executes for the value of the second loop.
  • The first loop executes 4 times, Then the second loop or inner loop executes n times for the n iteration of the first loop, for example, 1 time for the first iteration of the first loop, 2 times for the second iteration of the first loop and so on.
  • Then the inner loop executes (1+2+3+4) iteration which gives the result 10 iterations.
  • The sum initial value is 0 and the "sum++", increase the value of the sum by 1.
  • So the value of the sum becomes 10 after completing 10 iterations of the inner for loop.
  • Hence the 10 will be the output. So the Option d is the correct answer while the other is not.
