[Solved] Trouble with Military Time

Question

I have been trying to solve the military challenge in C. I wrote this code and it fails on test 3 and 5. I can not figure out what is wrong with it.

#include <stdio.h>
#include <string.h>

int hour, min;
char TOD[2]; //Time of Day
int main() {
scanf("%d:%d %s", &hour, &min, TOD);
if(strcmp(TOD, "PM") == 0 && hour != 12){
hour+=12;
}
if(strcmp(TOD, "AM") == 0 && hour == 12){
hour = 0;
}
if(min == 0){
printf("%d:%d0", hour, min);
}
else{
printf("%d:%d", hour, min);
}
return 0;
}

Coder Kitten That was it. Thank you.

Answer 3

In military time, leading zeros are usually added to hours and minutes less than 10. To ensure proper formatting, add zero padding when printing the time. When converting from AM to 24-hour format, if the input is 12:00 AM, the correct output should be 00:00. Currently, your code sets the hour to 0, but you should also handle zero-padding for the hour. https://www.screenmirroring.onl/how-to-play-pubg-on-smart-tv-using-screen-mirroring/

#include <stdio.h>
#include <string.h>

int hour, min;
char TOD[2]; //Time of Day

int main() {
scanf("%d:%d %s", &hour, &min, TOD);

if (strcmp(TOD, "PM") == 0 && hour != 12) {
hour += 12;
}
if (strcmp(TOD, "AM") == 0 && hour == 12) {
hour = 0;
}

if (hour == 0) {
printf("00:%02d", min); // Zero-padding for hour
} else {
printf("%02d:%02d", hour, min); // Zero-padding for both hour and minute
}

return 0;
}

In your code, converting time to military format mostly looks good, but there's a small mistake that you made in this code. A mistake is how you're handling minutes. When minutes are zero, you're printing an extra zero at the end, which isn't needed. You can try this below code that helps you to fix your mistake and run: https://www.publix-passport.com/

#include <stdio.h>
#include <string.h>

int main() {
int hour, min;
char TOD[3]; //Time of Day

scanf("%d:%d %s", &hour, &min, TOD);

if(strcmp(TOD, "PM") == 0 && hour != 12){
hour += 12;
}
if(strcmp(TOD, "AM") == 0 && hour == 12){
hour = 0;
}

printf("%02d:%02d", hour, min); // This will print the hour and min with leading zeros if needed

return 0;
}

I hope my suggestion will be helpful for everyone.
