I would say A. Test it and receive feedback
Answer:
When Scheme is a pure functional language, it cannot include the function DISPLAY. Since the pure functional languages will return the same value whenever the same expression is evaluated, and the DISPLAY would be the output and thus it cannot be part of the purely functional language. Thus in the pure functional language we can evaluate the expressions with the same arguments and it returns the same value since there is no state to change.
Explanation:
Answer : A Formula is a method, statement, or procedure for achieving something, especially reconciling different aims or positions. A function is an activity or purpose natural to or intended for a person or thing. The difference between the two is a function is a piece of code that executes a predefined calculation, while a formula is something you create yourself.
// this function will return 1 if the string sent in arguments is palindrome //else it will return 0
int palindrome(int start_of_string, int end_of_string, string &strr)
{
// base case to check if the string is not empty
if (start_of_string>= end_of_string)
return 1;
if (strr[start_of_string] != strr[end_of_string])
return 0;
// recursive call
return palindrome(++start_of_string, --end_of_string, strr);
}
Answer:
#include<iostream>
using namespace std;
class Money{
private:
int dollars;
int cents;
public:
Money(int d=0, int c=0){
setDollar(d);
setCent(c);
}
void setDollar(int d){
dollars = d;
}
void setCent(int c){
cents = c
}
int getDollar() {
return dollars;
}
int getCent() {
return cents;
}
double getMoney(){
return (dollars + (cents/100));
}
};
// testing the program.
int main(){
Money Acc1(3,50);
cout << M.getMoney() << endl;
Money Acc2;
Acc2.setDollars(20);
Acc2.setCents(30);
cout <<"$" << Acc2.getDollars() << "." << Acc2.getCents() << endl;
return 0;
}
Explanation:
The C++ source code defines the Money class and its methods, the class is used in the main function as a test to create the instances of the money class Acc1 and Acc2.
The object Acc2 is mutated and displayed with the "setDollar and setCent" and "getDollar and getCent" methods respectively.
