There's a mistake in the code, 1st Console.WriteLine should have "What's your name?" in it

I'm having a problem with the input program i've made with this code: using System; namespace DataTypesApp { class DataTypesProgram { static void Main(string[] args) { Console.Write("Enter the pieces of apples: "); int num = Convert.ToInt32(Console.Read()); Console.Write("Enter total price of "+ num +" apple(s): "); double num2 = Convert.ToInt32(Console.Read()); Console.ReadKey(); } } } During the program window, after I set the input number I have to the num variable, the num value should be rightfully seen based on what number I put there (for example, I input 6, where in the next sentence it should say "Enter total price of 6 apple(s): "), instead it adds 48 values off from the num variable from some unknown reason why ("Enter total price of 54 apple(s): "). We were using Visual Studio 2017 because our prof said that using the recent version is "Cheating".

Im kinda confused, why didn't you just write int age=int.Parse(Console.ReadLine());?

@porshkabir2535 9 ай бұрын

Because the input is considered as a string, so to use it as a integer, you need to convert it.

@@porshkabir2535 But int.Parse does actually convert a string to an int too, it would have given the same result. The difference is that int.Parse can only convert strings while Convert.ToInt32 can convert other data types too.

User interpolation rather than a + to tie your variables in a Console.WriteLine statement so like this Console.WriteLine($"Some text {variable}"); it is like a f string from python

A good introduction, but I was looking for how to check for specific keypresses.

I keep having this problem:( "Converting null literal or possible null value to non-nullable type."

I think this is only avoidable by using if-statements or catching exceptions like Bro mentioned at 3:22.

Ive found an explanation on Stackoverflow for the same problem I have currently now: Firstly, you are seeing this message because you have the C# 8 Nullable reference type feature enabled in your project. Console.ReadLine() returns a value that can be either a string or null but you are using it to set a variable of type string. Instead either use the var keyword which will implicitly set your variable to the same type as the return value or manually set your variable as type nullable string string?. the ? denotes a nullable reference type. You may then want to check that your variable does infact hold a string before you use it: string? NumInput = Console.ReadLine(); if (NumInput == null) { // ... } Written by Sean McCafferty To make it short: just put between string and name a ? and it should work. string? name
