Answer:
#include <iostream>
using namespace std;
struct StudentType{
    string studentName;
    int studentId;
}
int n;
char answer[20];
int main(){
    cout<< "Enter the size of the array: ";
    cin >> n;
    StudentType *student = new StudentType(n);
    for (int i = 0; i < n; i++){
        int name;
        int number;
        cin>> name;
        cin >> number;
        student[i].studentName = name;
        student[i].studentId = number;
    }
    for (int i = 0; i < 20; i++){
        cout<< "Enter answers: ";
        cin >> ans;
        answer[i] = ans;
    }
}
Explanation:
The C++ source code has three global variables namely, answer which is an array of character data type, StudentType which is a structure data type and the integer variable n. The main function declares and initializes the dynamic-spaced student array of the structure datatype with the n variable.
 
        
             
        
        
        
Answer:
The answer to the following question is the option "B".
Explanation:
The term REA stands for Resources, events, agents. It is a model that provides us an accounting system. In this system, we can re-engineer for the computer age and Integrate separate REA diagrams for individual or a comprehensive organization.  This process does not affect any event and agents who participate in events affecting shared resources. So the answer to this question is "none of the other entities".

Answer:
b. an unsigned integer? (convert it to decimal)
Explanation:
Computer systems represent data and instructions in bits to be stored and processed by the processor. The buses in the computer system transfer data and instructions to various locations. Some buses can be 32 or 64 bits wide, transporting data like the 32-bit number above which covert to an unsigned integer of 2,903,506,944.
