. NET entry-level Test Question 1: variables and expressions

Do it yourself. NET has been developing for three years. In the past three years, I have worked as a small website in my hometown, and I have been doing repetitive useless work. I came to Shanghai two months ago, and I have joined the company's foreign investment, I bought this C # entry-level Foundation and started reading it again. I have benefited a lot. Now I want to share the topic of every small chapter in this book. As your learning record.

(1) In the following code, how do I reference the name Great from the namespace fabulous code?

namespace fabulous{     //code in fabulous namespace      }namespace super{      namespace smashing      {             //great name defined      }}

(2) which of the following variables are invalid?

1. myVarableIsGood

2.99 Flake

3. _ floor

4. time2GetJiggyWidIt

5.wrox.com

 

(3) is the string supercalifragilistticexpialidocious too long to be placed in the string variable? Why?

 

(4) list the calculation steps of the following expressions based on the operator priority.

ResultVar + = var1 * var2 + var3 % var4/var5;

(5) Write a console application that requires you to enter int values and display their product. Tip: You can use the Convert. ToDouble () command to Convert the number you entered on the console to double. The command to Convert string to int Is Convert. IoInt32 ().

 

Well, the above is the question. Next, after a Huawei flash bullet, post the answer, which can be referred.

The answer is here:

(1): super. smashing. greate

(2): 99 Flask and wrox.com because the first one starts with a number and the second one has.

(3): theoretically, the length of a string is as long as the memory size is large, so this string can be placed in the string type.

(4): According to the operator priority, "*" "%" "/" is at the same level, followed by +, and finally "+ = ".

Two simple instances: resultVal + = (var1 * var2) + (var3% var4)/var5 ),

ResultVal + = (var1 * var2) + (var3% (var4/var5 ))

 

(5): Write down the pseudocode,

Int firtNum, secondNum, thiridNum, fourthNum;

1*2*3*4.
