Explanation:
The second for loop does 1 of 4 iterations for every 1 of 5 iterations of the parent loop. meaning it is 4 x 5 which is 20.
Answer:
The program to this question can be described as follows:
Program:
#include <iostream> //defining header file
using namespace std;
int main() //defining main method
{
int x1,rem,i=1; //defining integer variable
long Num=0;// defining long variable
cout << "Input a decimal number: "; // print message
cin >> x1; //input value by user
while (x1!=0) //loop for calculate binary number
{
//calculating binary value
rem= x1%2;
x1=x1/2;
Num =Num +rem*i;//holding calculate value
i=i*10;
}
cout <<Num;//print value
return 0;
}
Output:
Input a decimal number: 76
1001100
Explanation:
In the above code, four variable "x1, rem, i, and Num" is declared, in which three "x1, rem, and i" is an integer variable, and one "Num" is a long variable.
- In the x1 variable, we take input by the user and use the while loop to calculate its binary number.
- In the loop, first, we check x1 variable value is not equal to 0, inside we calculate it binary number that store in long "Num" variable, after calculating its binary number the print method "cout" is used to prints its value.
Answer:
1. FDD is a process and Analysts can use a FDD to create and use business functions and processes. It Requirements models are used when gathering requirements for a new system.
2. BPM is used on an ongoing basis for business process improvement. It is meant to improve order, insight and efficiency of the collective workflows that make up any given business process. BPM is meant to reduce any chaos within those collective workflows that make up a process and eliminate ad hoc workflow management. BPM means Business Process Management.
3. DFDs stands for Data Flow Diagram which will help software developers and designers to understand how they can take their next step to fit into the overall business process. DFDs paly key role for a successful requirements modeling.
4. UML can be used for modeling a system independent of a platform language. UML is a graphical language for visualizing, specifying, constructing, and documenting information about software-intensive systems. UML gives a standard way to write a system model, covering conceptual ideas.
Explanation:
Functional decomposition diagram (FDD) is used to identify functions and define their structure. It is a technique to decompose the complex problem into manageable pieces or individual elements to develop the application or product.
DFDs: It contains a process (shape) that represents the system to model, in this case, the "Food Ordering System". It also shows the participants who will interact with the system, called the external entities. In this example, Supplier, Kitchen, Manager and Customer are the entities who will interact with the system.
Unified Modeling Language (UML): Edraw UML Diagram is the application of choice for many software engineers and designers. The software is fully compatible with 64 and 32-bit Windows platforms from Windows XP to Windows 10.
