I am new in C# programming language and I confused with a question. I have a for loop that increase two times by one in one cycle, but in each cycle it increase once.
What is the reason it does omit the i++?
string inValue; for (int i = 0; i < 10; i++) { Console.Write("Enter Score{0}: ", i + 1); inValue = Console.ReadLine(); } The ++ increment operator increases value only by one
for (int i = 0; i < 10; i++) To increase twice:
for (int i = 0; i < 10; i+=2) { Console.Write("Enter Score{0}: ", i); } Read more: Increment (++) and Decrement (--) Operators
| If | Equivalent Action | Return value | | variable++ | variable += 1 | value of variable before | | | | incrementing |
The following row:
Console.Write("Enter Score{0}: ", i + 1); increases the value of i by plus 1 but that is not stored into i. It is like writing:
int b = i+1; // i is not affected. New value never stored back into i Console.Write("Enter Score{0}: ", b); Any of the following ways will increase value by 2:
//Option 1 for (int i = 0; i < 10; i +=2) //Option2 Console.Write("Enter Score{0}: ", i++); //Option3 i = i+1; Console.Write("Enter Score{0}: ", i); 
i++ means you just increase the i by 1 or simply you can just write the code like this i = i + 1. So if you want loop with increase i + 2, you can write down code like this:
for(int i = 0; i < 10; i += 2) { Console.Write("Enter Score{0}: ", i); inValue = Console.ReadLine(); } The loop will increase i by 2.
(i++) increases i by 1, it's like writing : i = i + 1. (i + 1) does not increases i.
