Answer:
// function with memory leak
void func_to_show_mem_leak() {
int *pointer;
pointer = malloc(10 * sizeof(int));
*(pointer+3) = 99;}
// driver code
int main()
{
// Call the function
// to get the memory leak
func_to_show_mem_leak();
return 0; }
Explanation:
Memory leakage occurs when programmers allocates memory by using new keyword and forgets to deallocate the memory by using delete() function or delete[] operator. One of the most memory leakage occurs by using wrong delete operator.
The delete operator should be used to free a single allocated memory space, whereas the delete [] operator should be used to free an array of data values.
Explanation:
calculators work by processing information in binary form. We're used to thinking of numbers in our normal base-ten system, in which there are ten digits to work with: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The binary number system is a base-two system, which means there are only two digits to work with: 0 and 1. Thus, when you input numbers into a calculator, the integrated circuit converts those numbers to binary strings of 0s and 1s.
The integrated circuits then use those strings of 0s and 1s to turn transistors on and off with electricity to perform the desired calculations. Since there are only two options in a binary system (0 or 1), these can easily be represented by turning transistors on and off, since on and off easily represent the binary option
Once a calculation has been completed, the answer in binary form is then converted back to our normal base-ten system and displayed on the calculator's display screen.
When accurately executed, the only cryptosystem known to be unbreakable is called: "One-time Pad" (Option D)
<h3>What is a Crypto System?</h3>
The one-time pad is a cryptographic approach that cannot be broken but needs the usage of a single-use pre-shared key that is not less than the message being delivered. A plaintext is coupled with a unique secret key in this manner.
It should be emphasized that in cryptography, a cryptosystem is a collection of cryptographic algorithms that are required to perform a certain security function, such as confidentiality. A cryptosystem is often composed of three algorithms: one just for key generation, one for encrypting, and one for deciphering.

B) Substitution cipher
C) Advanced Encryption Standard
D) One-time Pad
Answer:
Baselines
Explanation:
The idea of software configuration management is that of monitoring and controlling changes in the software. The baseline is the standard and formally accepted form of a software item that is meant to be configured. It is like a generally accepted reference point, which could be applied in effecting incremental changes in the software.
There are three types of baselines which are the functional, developmental, and product baselines. Functional baselines provide an overview of the functionality and specifications of a system. The product baseline encompasses both the functional and physical details of the system.
