Which of the following can be considered beta testing? A programmer at Linus Systems checks the integration of multiple modules
Iteru [2.4K]

Answer:

B. System users at URP feed data into a new information system to test its capability.

Explanation:

Beta testing is one of the final steps in  the production of a technological device. In Beta testing, the end user of the product is given the product to use for a specified period of time so as to validate its functionality. Beta testing would help the company manufacturing the product to actually ascertain the level of acceptance of the product by users and also determine whether to invest in the product or limit production.

Beta testing is preceded by alpha testing. It is done before the company begins actual marketing of the product. So, when the system users at URP feed data into a new information system to test its capability, that is beta testing.

30 points) Suppose you are given a string containing only the characters ( and ). In this problem, you will write a function to
navik [9.2K]

Answer:

The screenshot is attached below

Explanation:

The below program check balence of paranthesis using stack.

if the input charecter is ( then push to stack

if the input charecter is ) then pop top element and compair both elements for match.

Program:

public class Main

{

static class stack // create class for stack

{

int top=-1; // initialy stack is empty so top = -1

char items[] = new char[50]; // Create an array for stack to store stack elements

 

void push(char a) // Function push element to stack

{

if (top == 49) // chack stack is full ?

{

System.out.println("Stack full");

}

else

{

items[++top] = a; // increment the array index and store the element

}

}

 

char pop() // function to return the elements from stack

{

if (top == -1) // check the stack is empty

{

System.out.println("Empty stack");

return '\0';

}

else

{

char element = items[top]; // return the top element

top--; // Decrement the array index by one

return element;

}

}

 

boolean isEmpty() // Check the stack is empty or not

{

return (top == -1) ? true : false;

}

}

static boolean isMatch(char character1, char character2) // Check the input charecters are matching pairs or not

{

if (character1 == '(' && character2 == ')') // If they match return true

return true;

else

return false;

}

 

static boolean isBalanced(String parantheses) // check the input string is balenced or not

{

char[] exp = new char[parantheses.length()]; // Create a charecter array

for (int i = 0; i < parantheses.length(); i++) { // Convert the string parantheses to charecter array

exp[i] = parantheses.charAt(i);

}

stack st=new stack(); // Declare an empty character stack    

for(int i=0;i<exp.length;i++)

{  

if (exp[i] == '('))   // if input charecter is '(' push to stack

st.push(exp[i]);

if (exp[i] == ')') // if input charecter is ')' pop top element from stack

{

if (st.isEmpty())

{

return false;

}

 

else if ( !isMatch(st.pop(), exp[i]) ) // Call isMatch function

{

return false;

}

}

 

}

 

if (st.isEmpty())

return true; //balanced

else

{

return false; //not balanced

}

}

 

 

public static void main(String[] args)

{

 

System.out.println(isBalanced("()()()")); // Output true if string is balenced

 

}

 

}

write a program that prompts the user to input the length of a string as an integer, followed by the string and outputs the stri
dlinn [17]

OUTPUT of program :

Enter a string length: 5

Enter a string : hello

String in upper case letters is: HELLO

Enter a string length: 5

WRITE a Program that prompts the length of a string and the string in uppercase letters using dynamic arrays ?

#include <iostream>

#include <cstring>

#include <cctype>

using namespace std;

int main(){

char *str = new char[80];

int *num= new int[80];

char *str1=new char[80];

int len,i;

cout << "Enter a string: "

cin.get(str, 80);

cout << "Enter string length: "

cin.get(num, 80);

cout << "String in upper case letters is:"<< endl;

len = strlen(str);

for (i = 0; i <len; i++)

{

 *(str1+i)=toupper(*(str+i));

}

for(i=0;i<len;i++)

{

 cout<<*(str1+i);  

}

return 0;

}

C++ :

     

           Performance, effectiveness, and flexibility of usage were the design pillars of C++, which was created with systems programming, embedded, resource-constrained software, and big systems in mind. The software infrastructure and resource-constrained applications, such as desktop programmes, video games, servers, and performance-critical programmes, are two areas where C++ has been proven to be very useful.

                      Generic programming is made possible via C++ templates. Function, class, alias, and variable templates are supported in C++. Types, compile-time constants, and other templates can all be used to parameterize templates. At compile time, templates are implemented by instantiation. Compilers use particular inputs in place of a template's parameters to create a concrete instance of a class or function. Some substitutes are not possible, and an overload resolution policy with the motto "Substitution failure is not an error" eliminates these cases (SFINAE).                  

        C++ gives C features for object-oriented programming (OOP). It provides classes that offer the four features frequently found in OOP languages: polymorphism, inheritance, encapsulation, and abstraction. Support for deterministic destructors, which in turn provides support for the Resource Acquisition is Initialization (RAII) idea, sets C++ classes apart from classes in other programming languages.
