The implementation stage of the SDLC _____.

Karolina [17]

Answer:

d. involves analyzing end-user business requirements in order to refine project goals

Explanation:

In the software development life cycle, the implementation stage is the stage where the computer programmers begin the actual coding of the application required by the end-user. At this stage, the developer takes into account the needs and specifications of the customer.

For example, if the end-user wants a software application that can track payment records, the researcher at this stage begins using the right software to code programs that can effect this function.

Write a program that takes in an integer in the range 20-98 as input. The output is a countdown starting from the integer, and s

S_A_V [24]

Answer:

// program in C++.

#include <bits/stdc++.h>

using namespace std;

int main() {

// variable

int num;

cout<<"Enter the number between 20 and 98: ";

// read number

cin >> num;

while(num<20||num>98)

{

cout<<"Wrong input!!enter number between 20-98 only:";

cin>>num;

}

cout<<"The output is: ";

while(num % 10 != num /10)

{

// print numbers.

cout<<num<<" ";

// update num.

num--;

}

// display the number.

cout<<num<<endl;;

return 0;

}

Explanation:

Read a number from user and assign it to variable "num".Check if entered number is in between 20-98 or not.If input number is less than 20 or greater than 98 then ask again to enter a number between 20-98 until user enter a valid input.Then print the countdown from input number till both the digit of number are same.

Output:

Enter the number between 20 and 98: 99

Wrong input!!enter number between 20-98 only:12

Wrong input!!enter number between 20-98 only:93

The output is: 93 92 91 90 89 88

Enter the number between 20 and 98: 77

The output is: 77
