# Program to find the time after K minutes from given time

You are given a time T in 24-hour format (hh:mm) and a positive integer K, you have to tell the time after K minutes in 24-hour time.
Examples:

```Input: T = 12:43, K = 21
Output: 13:04

Input: T = 20:39, K = 534
Output: 05:33```

Approach:

• Convert the given time in minutes
• Add K to it let it be equal to M.
• Convert the M minutes in 24 hours format accordingly.

## C++

 `#include ` `using` `namespace` `std; ` `   `  `// function to obtain the new time ` `void` `findTime(string T, ``int` `K) ` `{ ` `   `  `    ``// convert the given time in minutes ` `    ``int` `minutes = ((T[0] - ``'0'``) ` `                       ``* 10 ` `                   ``+ T[1] - ``'0'``) ` `                      ``* 60 ` `                  ``+ ((T[3] - ``'0'``) ` `                         ``* 10 ` `                     ``+ T[4] - ``'0'``); ` `   `  `    ``// Add K to current minutes ` `    ``minutes += K; ` `   `  `    ``// Obtain the new hour ` `    ``// and new minutes from minutes ` `    ``int` `hour = (minutes / 60) % 24; ` `   `  `    ``int` `min = minutes % 60; ` `   `  `    ``// Print the hour in appropriate format ` `    ``if` `(hour < 10) { ` `        ``cout << 0 << hour << ``":"``; ` `    ``} ` `    ``else` `{ ` `        ``cout << hour << ``":"``; ` `    ``} ` `   `  `    ``// Print the minute in appropriate format ` `    ``if` `(min < 10) { ` `        ``cout << 0 << min; ` `    ``} ` `    ``else` `{ ` `        ``cout << min; ` `    ``} ` `} ` `   `  `// Driver code ` `int` `main() ` `{ ` `   `  `    ``string T = ``"21:39"``; ` `   `  `    ``int` `K = 43; ` `   `  `    ``findTime(T, K); ` `}`
