Write a C program that reads a time from the keyboard. The time should be in the format "HH:MM AM" or "HH:MM PM". Hours can be one or two digits, minutes are exactly two digits, and AM/PM can be in any mixture of uppercase and lowercase. For example, "1:10 am", "12:05 PM", and "12:45 aM" are valid inputs. Your program should include a function that takes a string parameter containing the time. This function should convert the time into a four-digit military time based on a 24-hour clock. For example, "1:10 AM" would output "0110 hours", "11:30 PM" would output "2330 hours", "12:15 AM" would output "0015 hours", and "5:05 Pm" would output "1705 hours". The function should return a string to be written to the screen by the main function

Check the explanation

Explanation:

C++ code:

#include <bits/stdc++.h>

using namespace std;

string convert(string s){

  int l=s.length();

  string ans=" hours";

  if(l==7){

      if(s[5]=='a'||s[5]=='A'){

          ans[0]='0';

          ans[1]=s[0];

          ans[2]=s[2];

          ans[3]=s[3];

else{

      if(s[6]=='a'||s[6]=='A'){

          ans[0]=s[0];

          ans[1]=s[1];

          ans[2]=s[3];

          ans[3]=s[4];

  return ans;

}

int main(){

  cout<<"Enter time: ";

  string s;

  getline(cin,s);

  cout<<"Corresponding military time is "<<convert(s)<<endl;

return 0;

See explaination

Explanation:

#include <iostream>

#include <stdio.h>

#include <string>

#include <cctype>

#include <stdlib.h>

#include <sstream>

using namespace std;

string itoa(int num)

{

stringstream converter;

converter << num;

return converter.str();

}

string convert(string str){

size_t pos = str.find_first_of(':');

string hour = str.substr(0,pos);

string min = str.substr(pos+1,2);

string ampm = str.substr(pos+4,2);

int h = atoi(hour.c_str())%12;

if(ampm == "pm" || ampm == "Pm" || ampm == "PM" || ampm == "pM")

hour = itoa(h+12);

else if(h == 0)

hour = "00";

else if(h<10)

hour = "0" + hour;

string mtime = hour + min;

return mtime;

}

int main() {

string ntime;

cout<<"Enter time: ";

getline(cin,ntime);

cout<<"Corresponding military time is "<<convert(ntime)<<" hours";

return 0;

}
