Answer:
a. True
Explanation:
The fractional_part function divides the numerator by the denominator, and in turn returns just the fractional part, which is usually a number between 0 and 1.
When the denominator is 0, it produces an error result, instead of attempting the division, the function can be programmed to return "Math Error: cannot be divided by zero", as shown in the following Python code;
def fractional_part(numerator, denominator):
if denominator == 0:
return "Math Error: cannot be divided by zero"
return (numerator % denominator)/denominator
Answer:
#include<iostream>
#include<cstring>
#include <algorithm>
using namespace std;
class Student{
public:
string name;
int rollNo;
Student(){
}
Student(string n, int r){
name = n;
rollNo = r;
}
};
class ClassRoom{
public:
Student stud[10];
int count;
ClassRoom(){
count = 0;
}
void addStudent(string str,int roll){
Student s(str,roll);
stud[count++] = s;
}
Student * getAllStudents(){
return stud;
}
};
int main()
{
string name;
char temp[20];
int rollNo, N, i;
Student * students;
ClassRoom classRoom;
i=0;
while(getline(cin, name) && cin.getline(temp,20)&&i<10){
rollNo = atoi(temp);
classRoom.addStudent(name, rollNo);
i++;
}
N = i;
students = classRoom.getAllStudents();
for(int i=0 ; i < N; i++){
cout << (students+i)->rollNo << " - " << (students+i)->name;
if(i<N-1)
cout<<endl;
}
return 0;
}
Explanation:
- In the addStudent method, increment the counter and as the value of variable s to the the stud array.
- In the getAllStudents method, return all the students.
- Finally in the main method, display the name and roll no. of students.
Answer: A- Public Key Encryption
Explanation: The Public key Encryption is used prevalently on the web, it allows for secure messages to be sent between parties without having to agree on, or share, a secret key. It uses an asymmetric encryption scheme in which the encryption key is made public, but the decryption key is kept private.
It’s true because it’s also called “flash memory”
