PadLeft

Question

Please explain me, what padleft is. In my opinion I consider that padleft is the sama as sedwidth iomanip like inserting of certain chars onto the existing string in appropriate manner so that the new returned string will have total length equals to the int number passed as argument of pad itself. The main condition must be considered is that the
int number passed as argument must be greater than the initial length of existing string itself. So if I have string s="hello" length=5, then I use s.padLeft(6,"*") then it Will return new string s= *hello. We can easily understand that 6 > 5, and 5 is the initial length of s.

Answer 1

You're correct. PadLeft is a method used to pad a string with additional characters on the left side until the string reaches a specified length. It takes two parameters e.g. total length you want the resulting string will be and the another parameter is character to use for padding, often space or any character. It checks if the length of the existing string is less than the specified total length. If it adds the padding characters to the left side of the string until it reaches the desired length. Remember, if the length of the existing string is already equal to or greater than the specified length, no padding is added, and the original string is returned.

For your example, if you use PadLeft(6, '*') to specify that we want the resulting string to have a total length of 6 characters, padding with '*' on the left side. Since the length of s is less than 6, it adds one '*' character to the left side of the string, resulting in "*hello".
