Question

What is the value of the variable named s after the following statements have been executed?

string fullName = "Miller, Edward";
int i = fullName.IndexOf(",");
string s = fullName.Substring(i + 1);
a. Miller
b. Miller,
c. , Edward
d. Edward

Answer 1

The value of the variable 's' after the code execution is " Edward", with a leading space, as it starts from the character after the comma in the fullName string.

Step-by-step explanation:

The value of the variable named s after executing the statements will be " Edward". When analyzing the code, fullName.IndexOf(",") will find the position of the comma in the string. Since fullName is "Miller, Edward", the comma is at index 6.

The fullName.Substring(i + 1) method will return a new string that is a substring of fullName starting from the character after the comma, which is index 7. Therefore, fullName.Substring(i + 1) returns " Edward", including the leading space.
