"how we write a program for" time swap" in c plus plus only with string"

Program Description

The program you are asking about is a time swap program written in C++ using strings. The purpose of the program is to swap the hours and minutes of a given time.

Program Steps:

1. Include the necessary header files:

#include <iostream>
#include <string>

1. Define the main function:

int main() {
    // code goes here
    return 0;
}

1. Declare the variables to store the time:

std::string time;
std::string hours;
std::string minutes;

1. Get the input for the time from the user:

std::cout << "Enter the time in HH:MM format: ";
std::cin >> time;

1. Extract the hours and minutes from the input time:

hours = time.substr(0, 2);
minutes = time.substr(3, 2);

1. Swap the hours and minutes:

std::string swappedTime = minutes + ':' + hours;

1. Print the swapped time:

std::cout << "Swapped Time: " << swappedTime << std::endl;

Complete Program Example:

#include <iostream>
#include <string>

int main() {
    std::string time;
    std::string hours;
    std::string minutes;

    std::cout << "Enter the time in HH:MM format: ";
    std::cin >> time;

    hours = time.substr(0, 2);
    minutes = time.substr(3, 2);

    std::string swappedTime = minutes + ':' + hours;

    std::cout << "Swapped Time: " << swappedTime << std::endl;

    return 0;
}

This program prompts the user to enter a time in the format HH:MM, extracts the hours and minutes, swaps them, and then prints the swapped time.
