using A = System.Console;
public void point()
{
int hour, minute;
A.Write("Enter Time (HH:MM) = ");
hour = A.Read();
A.Write(":");
minute = A.Read();
}
I want it to be like
"Enter Time (HH:MM) = 12(hour input):49(minute input)"
but it coming like
"Enter Time (HH:MM) = 12(hour input)
:49(minute input)
Simplest way (assuming you are reading from Console, and user will enter hour then press Enter, then enter minute and press Enter):
static void Main(string[] args)
{
int hour = 0, minute = 0;
const int MAX_NUMBER_OF_DIGITS = 2 ;
Console.Write("Enter Time (HH:MM) = ");
// store cursor position
int cursorLeft = Console.CursorLeft;
int cursorTop = Console.CursorTop;
// use ReadLine, else you will only get 1 character
// i.e. number more than 1 digits will not work
hour = int.Parse(Console.ReadLine());
Console.SetCursorPosition(cursorLeft + MAX_NUMBER_OF_DIGITS , cursorTop);
Console.Write(":");
minute = int.Parse(Console.ReadLine());
// Nitpickers! purposefully not using String.Format,
// or $, since want to keep it simple!
Console.Write("You entered: " + hour + ":" + minute);
}
Output:
Enter Time (HH:MM) = 17:55
You entered: 17:55
Though I would rather recommend you better and less error prone way like this (where user inputs HH:MM and presses Enter a single time i.e. enters a single string including : i.e. colon):
static void Main(string[] args)
{
int hour = 0, minute = 0;
Console.Write("Enter Time in format HH:MM = ");
string enteredNumber = Console.ReadLine();
string[] aryNumbers = enteredNumber.Split(':');
if (aryNumbers.Length != 2)
{
Console.Write("Invalid time entered!");
}
else
{
hour = int.Parse(aryNumbers[0]);
minute = int.Parse(aryNumbers[1]);
// Nitpickers! purposefully not using String.Format,
// or $, since want to keep it simple!
Console.Write("You entered: " + hour + ":" + minute);
}
}
Assuming that A is Console, you can do like this:
static void Main()
{
int hour, minute;
char[] hourChars = new char[2];
Console.Write("Enter Time (HH:MM) = ");
hourChars[0] = Console.ReadKey().KeyChar;
hourChars[1] = Console.ReadKey().KeyChar;
var hourString = new String(hourChars);
hour = int.Parse(hourString);
Console.Write(":");
minute = Console.Read();
}
Assuming A is the standard c# Console then you can use ReadKey instead of Read
ReadKey will read only one character at a time but it will not force you to hit enter which is the cause for the new line.
static void Main()
{
char h1, h2, m1, m2;
Console.Write("Enter Time (HH:MM) = ");
h1 = Console.ReadKey().KeyChar;
h2 = Console.ReadKey().KeyChar;
Console.Write(":");
m1 = Console.ReadKey().KeyChar;
m2 = Console.ReadKey().KeyChar;
}
I will leave the actual value parsing as an exercise.
Ahere ?Read()andWrite()work, this looks like it'd be confusing to the user since you're initially prompting for both the hours and minutes, yet your code seems to be expecting it be entered as<Hours><Enter><Minutes><Enter>. I would expect your first call toRead()to fail when the user inputs<Hours>:<Minutes><Enter>, even though that's what your asking them to type. I think you'd be better off reading the hours and minutes as oneStringand just parsing that into its component values.
