string str = "Student_123_"; I need to replace the last character "_" with ",". I did it like this.
str.Remove(str.Length -1, 1); str = str + ","; However, is it possible to achieve it more efficiently. may be one line of code.?? BTW, last character can be any character. So Replace wont work here.

Every string in C ends with '\0'. So you need do this: int size = strlen(my_str); //Total size of string my_str[size-1] = '\0'; This way, you remove the last char.
Strings are actually one-dimensional array of characters terminated by a null character '\0'. Thus a null-terminated string contains the characters that comprise the string followed by a null. The following declaration and initialization create a string consisting of the word "Hello".
Use the String. slice() method to remove the last 3 characters from a string, e.g. const withoutLast3 = str. slice(0, -3); . The slice method will return a new string that doesn't contain the last 3 characters of the original string.
No.
In C# strings are immutable and thus you can not change the string "in-place". You must first remove a part of the string and then create a new string. In fact, this is also means your original code is wrong, since str.Remove(str.Length -1, 1); doesn't change str at all, it returns a new string! This should do:
str = str.Remove(str.Length -1, 1) + ","; If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
