Question

PLEASE do the following problem in C++ with the screenshot of the output. THANKS!

There are 3 parts. (1) Write a C++ program to check an input string by user is palindrome or not. (2) Write a program to check whether the year provided by a user is a leap year or not. (3) Write a program which accepts days as integer and display total number of years, months and days in it. For example : If user input as 856 days the output should be 2 years 4 months 6 days.

Answer 1

Program 1:

#include<iostream>

#include<string>

using namespace std;

int main()

{

    string s,revs;

    int i;

    cout<<"Enter a string:";

    getline(cin,s);

    for(i=s.size()-1;i>=0;i--)

    {

        revs.push_back(s[i]);

    }

    if(s.compare(revs)==0)

        cout<<"String is a Palindrome\n";

    else

        cout<<"String is not a Palindrome\n";

    

    return 0;

}

Output:

Program 2:

#include<iostream>

using namespace std;

int main()

{

    int year;

    cout<<"Enter a year:";

    cin>>year;

    if(year%4==0 && year%400==0)

        cout<<"Entered year is a leap year\n";

    else if(year%4==0 && year%100!=0)

        cout<<"Entered year is a leap year\n";

    else

        cout<<"Entered year is not a leap year\n";

    

    return 0;

}

Output:

Program 3:

#include<iostream>

using namespace std;

int main()

{

    int days,years=0,months=0;

    cout<<"Enter number of days:";

    cin>>days;

    if(days>=365)

    {

        years=days/365;

        days=days-365*years;

    }

    if(days>=30)

    {

        months=days/30;

        days=days-30*months;

    }

    cout<<years<<" years "<<months<<" months "<<days<<" days\n";

    return 0;

}

Output:
