well here it is... I find good use for it.

#include <iostream>
#include <stdlib.h>

using namespace std;

int main(int argc, char *argv[])
{

cout << "Simple Calculator By: Michael Hedden (The_kid)\n\n";

cout << "Enter \"5\" to quit";


double type;
double restart;
double fnumber;
double snumber;
double answer;

line20:
cout << "\n\n\n\nWhat type of Math would you like to do? (+[1], -[2], x[3], or ö[4]) ";
cin >> type;

if (type==1)
    {
    
    cout << "\n\n\aPlease input 2 numbers separated by a space, and I shall add them: ";
    cin >> fnumber;
    cin >> snumber;
    
    answer = fnumber + snumber;
    
    cout << "\n\nThe correct answer is: " << answer << "\n\n\n";
    }
    
if (type==2)
    {
    
    cout << "\n\n\aPlease input 2 numbers separated by a space, and I shall subtract them: ";
    cin >> fnumber;
    cin >> snumber;
    
    answer = fnumber - snumber;
    
    cout << "\n\nThe correct answer is: " << answer << "\n\n\n";
    }
    
if (type==3)
    {
    
    cout << "\n\n\aPlease input 2 numbers separated by a space, and I shall multiply them: ";
    cin >> fnumber;
    cin >> snumber;
    
    answer = fnumber * snumber;
    
    cout << "\n\nThe correct answer is: " << answer << "\n\n\n";
    }
    
if (type==4)
    {
    
    cout << "\n\n\aPlease input 2 numbers separated by a space, and I shall divide them: ";
    cin >> fnumber;
    cin >> snumber;
    
    answer = fnumber / snumber;
    
    cout << "\n\nThe correct answer is: " << answer << "\n\n\n";
    }
    
if (type==5)
    {
    
    return 0;
    
    }
    
    
if (type>=6)
    {
    INTerror:
    cout << "\n\nI'm sorry, but you have incountered an unexpected error, please try again.";

Here is my calculator code for days calculations from a certain date :
 

#include <iostream>
#include <string>
#include <sstream>
#include <ctime>

using namespace std;

// Function to check if a year is a leap year
bool isLeapYear(int year) {
    if ((year % 4 == 0 && year % 100 != 0) || (year % 400 == 0)) {
        return true;
    }
    return false;
}

// Function to get the number of days in a month
int daysInMonth(int month, int year) {
    switch (month) {
        case 1: case 3: case 5: case 7: case 8: case 10: case 12: // 31 days
            return 31;
        case 4: case 6: case 9: case 11: // 30 days
            return 30;
        case 2: // February (28 or 29 days)
            return isLeapYear(year) ? 29 : 28;
        default:
            return 0;
    }
}

// Function to calculate the difference in days between two dates
int calculateDays(int day1, int month1, int year1, int day2, int month2, int year2) {
    struct tm a = {0}, b = {0};
    a.tm_year = year1 - 1900;
    a.tm_mon = month1 - 1;
    a.tm_mday = day1;
    b.tm_year = year2 - 1900;
    b.tm_mon = month2 - 1;
    b.tm_mday = day2;

    time_t x = mktime(&a);
    time_t y = mktime(&b);
    
    // Return the absolute difference in days
    return abs(difftime(y, x) / (60 * 60 * 24));
}

int main() {
    int day1, month1, year1, day2, month2, year2;

    cout << "Enter the first date (YYYY MM DD): ";
    cin >> year1 >> month1 >> day1;

    cout << "Enter the second date (YYYY MM DD): ";
    cin >> year2 >> month2 >> day2;

    // Calculate the difference in days
    int daysDifference = calculateDays(day1, month1, year1, day2, month2, year2);

    cout << "The number of days between the two dates is: " << daysDifference << " days." << endl;

Just find out this site calculatro site calculadoradediasfechasanos.com for days calculator but their code is in different language.
