How to get tomorrows date in C++

Answer 1

#include <iostream>
#include <ctime>

int main() {
    // Get current time
    std::time_t now = std::time(nullptr);
    std::tm* localTime = std::localtime(&now);

    // Add one day to the current date
    localTime->tm_mday += 1;

    // Normalize the time structure in case the day exceeds the month's limits
    std::mktime(localTime);

    std::cout << "Tomorrow's date is: "
              << (localTime->tm_year + 1900) << "-"
              << (localTime->tm_mon + 1) << "-"
              << localTime->tm_mday << std::endl;
}
