Convert given time into words

  • Difficulty Level : Basic
  • Last Updated : 29 Apr, 2021

Given a time in the format of hh:mm (12-hour format) 0 < hh < 12, 0 <= mm < 60. The task is to convert it into words as shown:
Examples : 
 

Input : h = 5, m = 0
Output : five o' clock

Input : h = 6, m = 24
Output : twenty four minutes past six

Corner cases are m = 0, m = 15, m = 30 and m = 45.
 

6:00 six o'clock
6:10 ten minutes past six
6:15 quarter past six
6:30 half past six
6:45 quarter to seven
6:47 thirteen minutes to seven

 

The idea is to use the if-else-if statement to determine the time in words. According to the above-given example, on the basis of minutes, we can categorize time in words into 8, which are minutes equal to 0, 15, 30, 45, 1, 59, and in a range less than 30 or greater than 30. Check the value of minutes and print accordingly.
Below is the implementation of this approach:
 

C++




// C++ program to convert time into words
#include <bits/stdc++.h>
using namespace std;
 
// Print Time in words.
void printWords(int h, int m)
{
    char nums[][64] = { "zero", "one", "two", "three", "four",
                        "five", "six", "seven", "eight", "nine",
                        "ten", "eleven", "twelve", "thirteen",
                        "fourteen", "fifteen", "sixteen", "seventeen",
                        "eighteen", "nineteen", "twenty", "twenty one",
                        "twenty two", "twenty three", "twenty four",
                        "twenty five", "twenty six", "twenty seven",
                        "twenty eight", "twenty nine",
                      };
 
    if (m == 0)
        printf("%s o' clock\n", nums[h]);
 
    else if (m == 1)
        printf("one minute past %s\n", nums[h]);
 
    else if (m == 59)
        printf("one minute to %s\n", nums[(h % 12) + 1]);
 
    else if (m == 15)
        printf("quarter past %s\n", nums[h]);
 
    else if (m == 30)
        printf("half past %s\n", nums[h]);
 
    else if (m == 45)
        printf("quarter to %s\n", nums[(h % 12) + 1]);
 
    else if (m <= 30)
        printf("%s minutes past %s\n", nums[m], nums[h]);
 
    else if (m > 30)
        printf("%s minutes to %s\n", nums[60 - m],
                                     nums[(h % 12) + 1]);
}
 
// Driven Program
int main()
{
    int h = 6;
    int m = 24;
 
    printWords(h, m);
    return 0;
}
