Identify the programmer’s responsibility in maximizing the programs reliability by
Gekata [30.6K]

Software has to be reliable so that it does not create conflict or negative feelings amongst those who use it.

In this world where humans increasingly rely on the internet and software for information, programmers have to take special care so as to ensure that the members of the society are not affected negatively.

For instance, there have been moments when software led to negative effects such as:

  • when Goøgle's algorithm tagged a black couple as gorillas
  • Facebøok's algorithm tagged black men as gorillas
  • Goøgle maps gave people the wrong directions

These are but a few instances where algorithms have messed up.

We can therefore conclude that it is important that programmers take extra care when designing programs so that they do not lead to negative feelings.

Consider the following line of code: if (x &lt; 12 || (r – 3 &gt; 12)) Write three valid mutants of this ground string (based on
Nata [24]

Answer:

See explaination

Explanation:

Mutation Testing:

Mutation Testing is a type of software testing where we mutate (change) certain statements in the source code and check if the test cases are able to find the errors. It is a type of White Box Testing which is mainly used for Unit Testing. The changes in the mutant program are kept extremely small, so it does not affect the overall objective of the program.

We say a mutant is valid if it is syntactically correct. We say a mutant is useful if, in addition to being valid, its behavior differs from the behavior of the original program for no more than a small subset of program test cases.

VALID MUTANTS

1. if (x < 12 && (r – 3 > 12)) LOR

2. if (x < 12 || (r – 3 < 12)) ROR

3. if (x < 12 || (x – 3 < 12)) IVR

INVALID MUTANTS

1. if (x < 12 ||(r – 3 > 12) UPR

2. if (x < 12 (r – 3 < 12)) MLO

3. (x < 12 || (x – 3 < 12)) CSM

Note:

LOR: LOGICAL OPERATOR REPLACEMENT

ROR: RELATIONAL OPERATOR REPLACEMENT

IVR: INVALID VARIABLE REPLACEMENT

UPR: UNBALENCED PARANTHISIS REPLACEMENT

MLO: MISSING LOGICAL OPERATOR REPLACEMENT

CSM: CONTROL OPERATOR MISSING REPLACEMEN

Using the constant, declare a 1D array to store 10 integers ii. Write a loop that fills the array with 10 random numbers g
Airida [17]

Answer:

Following are the code to this question:

#include <iostream>//defining header file

#include <cstdlib>//defining header file

using namespace std;

int main()//defining main method

{

const int ax[10]={1,2,3,4,5,6,7,8,9,10};//defining a const array ax that store 10 numbers

int r_num[10];//defining an array r_num

int i;//defining integer variable

for(i=0;i<10;i++)//defining for loop to calculate and store random numbers in array

{

   r_num[i]=rand()%100; //use rand function to store value in array

}

cout<<"Elements of the array that stores 10 random numbers: "<<endl;//print message

for(i=0;i<10;i++)//defining for loop for print array value

{

   cout<<r_num[i]<<endl;//print array value

}

return 0;

}

Output:

Elements of the array that stores 10 random numbers:

Explanation:

In the above-given program, two arrays "ax, and r_num" is declared that store value in it, in which the ax array use the const keyword and in the r_num it uses the loop and random function which can be defined as follows:

In the second array "r_num", two for loop is declared, in which the first loop uses the rand function to store value in the array, and in the second array, it prints the value of the array.
