Question

[Using the following code] compile with g++ main.cpp and functions.cpp. Declare the function in functions.h, implement the function in functions.cpp, and main.cpp.

#include<iostream>
#include<string>

using namespace std;

bool leap(int year){
if(year<0){
return false;
}
else if(year % 400 == 0){
return true;
}
else if(year % 100 == 0){
return false;
}
else if(year % 4 == 0){
return true;
}
return false;
}

int main() {
int year;
cin>>year;
if(leap(year)){
cout<<year<<" is a leap year.";
}
else{
cout<<year<<" is not a leap year.";
}

return 0;
}

Answer 1

bool leap(int year);

#include "functions.h"

bool leap(int year) {
    if (year < 0) {
        return false;
    } else if (year % 400 == 0) {
        return true;
    } else if (year % 100 == 0) {
        return false;
    } else if (year % 4 == 0) {
        return true;
    }
    return false;
}

#include<iostream>
#include<string>
#include "functions.h"

using namespace std;

int main() {
    int year;
    cin >> year;
    if (leap(year)) {
        cout << year << " is a leap year.";
    } else {
        cout << year << " is not a leap year.";
    }
    return 0;
