They are declared with the DECLARE statement.
They can be declared with an expression that's used as the default value.
They must have names that are different from the names of any columns used in any SELECT statement within the stored

Answers
They store values that can change as a program executes is not true about variables. Hence option a is correct.
What are variables?Variables are defined as a value that is subject to vary depending on external factors or input to the program. In any programming language, a variable is a designated chunk of computer memory with some data within.
An element cannot be taken away. A amount is represented by a variable. As a result, X is a quantity that is 1. Variables can only be defined once. The variable cannot be declared again once it has been defined. The overall variable costs vary directly as a function of activity level, or the quantity produced.
Thus, they store values that can change as a program executes is not true about variables. Hence option a is correct.

The following code should take a number as input, multiply it by 8, and print the result. In line 2 of the code below, the * symbol represents multiplication. Fix the errors so that the code works correctly: input ("Enter a number: ") print (num * 8)
Answers
Answer:
The correct program is as follows:
num = float(input ("Enter a number: "))
print(num * 8)
Explanation:
Notice the difference between (1)
num = float(input ("Enter a number: "))
print (num * 8)
and (2)
input ("Enter a number: ")
print(num * 8)
Program 1 is correct because:
- On line 1, it takes user input in numeric form, unlike (2) which takes it input as string
- On line 2, the program multiplies the user input by 8 and prints it out

P1: Write a function called FindPrimes that takes 2 scalars, lowerRange and upperRange, and produces a 1D array called outPrimes1. The function finds all the prime numbers within the range defined by lower Range and upperRange. The output outPrimes1 is a 1D array with all the primes within the specified range. Remember that a prime number is a whole number greater than 1 whose only factors are 1 and itself. The input arguments (lowerRange, upperRange) are two (numeric) scalars. The output argument (outPrimes1) is a 1xm (numeric) array. Restrictions: Do not use the primes() function. Hint: use a for loop to go through the entire range and check if the number is prime or not using the isprime() function. For example: For the given inputs: lowerRange = 2; upperRange= 20; On calling FindPrimes: outPrimes1 Find Primes (lower Range, upperRange) produces, outPrimes1 = 1x8 2 3 5 7 11 13 17 19 In outPrimes1 all the prime numbers contained within the range of lowerRange=2 and upperRange=20 are shown.

Answers
The function FindPrimes takes two scalar inputs, lowerRange and upperRange, and returns two 1D arrays: outPrimes1 and outPrimes2. The function finds all the prime numbers within the range specified by lowerRange and upperRange.
1. The FindPrimes function first uses a for loop to iterate through the entire range defined by lowerRange and upperRange. Within the loop, each number is checked for primality using the isprime() function. If a number is found to be prime, it is appended to the outPrimes1 array.
2. Once outPrimes1 is populated with all the prime numbers within the range, a while loop is used to iterate through the elements of outPrimes1. The loop checks if the sum of the prime numbers encountered so far is less than the highest prime number in outPrimes1. If the sum is less, the prime number is appended to the outPrimes2 array.
3. Finally, the function returns both outPrimes1 and outPrimes2 as output. outPrimes1 contains all the prime numbers within the specified range, while outPrimes2 contains a subset of prime numbers whose sum is less than the highest prime number in outPrimes1.
4. In the given example, FindPrimes with lowerRange = 2 and upperRange = 20 would produce outPrimes1 = [2, 3, 5, 7, 11, 13, 17, 19] and outPrimes2 = [2, 3, 5, 7]. The sum of the prime numbers in outPrimes2 is 17, which is less than the highest prime number in outPrimes1 (19).

How did Native Americans gain from the long cattle drives?When Oklahoma became a state in 1907, the reservation system there was essentially abolished. In Indian Territory, cattle were and are the dominant economic driver.
Tolls on moving livestock, exporting their own animals, and leasing their territory for grazing were all sources of income for the tribes.
There were several cattle drives between 1867 and 1893. Cattle drives were conducted to supply the demand for beef in the east and to provide the cattlemen with a means of livelihood after the Civil War when the great cities in the northeast lacked livestock.

How is new operator different than malloc? (2 marks)
What is the difference between function overloading and operator
overloading? (2 marks)
Answers
Difference between new operator and malloc: Memory Allocation, Type Safety, Constructor Invocation, Return Type, Error Handling:.
Memory Allocation: The new operator is used in C++ to dynamically allocate memory for objects, while malloc is a function in C used for dynamic memory allocation.
Type Safety: The new operator ensures type safety by automatically determining the size of the object based on its data type, while malloc requires manual specification of the size in bytes.
Constructor Invocation: When using new, the constructor of the object is called to initialize its state, whereas malloc does not invoke any constructor. This allows new to handle complex objects with constructors and destructors, while malloc is suitable for allocating raw memory.
Return Type: The new operator returns a pointer to the allocated object, automatically casting it to the appropriate type. malloc returns a void* pointer, requiring explicit casting to the desired type.
Error Handling: If the new operator fails to allocate memory, it throws an exception (std::bad_alloc), whereas malloc returns NULL if it fails to allocate memory.
Difference between function overloading and operator overloading:
Function Overloading: It allows multiple functions with the same name but different parameters in a class or namespace. The compiler differentiates between these functions based on the number, types, or order of the parameters. Function overloading provides flexibility and code reusability by allowing similar operations to be performed on different data types or with different argument combinations.
Operator Overloading: It enables operators such as +, -, *, /, etc., to be redefined for custom types. It allows objects of a class to behave like built-in types with respect to operators. Operator overloading is achieved by defining member functions or global functions with the operator keyword followed by the operator symbol. It provides a concise and intuitive way to work with objects, enabling natural syntax for custom operations.
In summary, function overloading is used to define multiple functions with the same name but different parameters, while operator overloading allows custom types to redefine the behavior of operators.
