Convert given time into words (original) (raw)

Last Updated : 16 Feb, 2023

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]);
