Kneel and beg for the C language program tutorial, go up to 100 first, and get it added.

Let's read a book and calm down and read it.

Tsinghua University publishes: "Computer Programs - C Language" is a good book.

If it is to cope with the second national exam, make more than 5 sets of written test papers, and it should be no problem to summarize and pass. For the computer-based test, you can buy 100 questions in Nankai, which is basically a question bank. After completing 100 questions, there are no problems at all in the computer-based test.

Let's take a good look at the book first.

#include

int main()

int sum=0;

for(int i=1;i<=100;i++)sum=sum+i;

Cout<> 1. Calculate the steps of adding 1 to 100 in C.

1. First of all, open Visual C++;

2. Select the file and create a new one;

<>4. Select an empty project and complete it;

5. Click the file again and create a new one.

6. Select C++Source File and enter the file name, click OK;

9. In the end, we got the result we wanted, and the answer was 5050.

#include

using namespace std;

int main()

In the hint"Please enter the starting number"1;

In the hint"Please enter the number of terminations"100;

Result: 5050

If you want to count this type of addition as a result, include

getsum(int sum,int num)int main()

int sum=0;

getsum(sum,100);

cout<

Don't leave it to the CPU if you can calculate it yourself, the CPU is reserved for the user, and it has nothing to do with the programmer.

Upstairs is the right solution. This program is just a for loop exercise. If you're learning C++, I recommend you take a look at C++ Premier. Very good book.

This kind of problem should be a programming type of question, the kind where you can get a more perfect answer, I don't understand, I hope it can help you.

1 Do 100 with C programming!How to write a program. Urgent!

1. Topic: Write a program to calculate 100 accurately! value.

2. Purpose and requirements.

1. Objective: To cultivate students' ability to comprehensively use C++ language for program design, to strengthen students' initial understanding of software engineering methods, to improve the ability of software system analysis and program document establishment, induction and summary, and to train students to use the standard functions and typical algorithms provided by the system for design. It mainly trains students to use the standard functions and typical algorithms provided by the system to carry out innovative design.

2 Basic Requirements:

1) It is required to use the idea of C++ to complete the design of the program.

2) Require accurate calculations of 100! value.

3 Innovation requirements.

After the basic requirements are met, innovative design is carried out to optimize the algorithm.

4. Requirements for writing design reports.

The following aspects are included in the design report:

1 Design the topic.

2 Design ideas.

1) Divide functional modules.

2) Determine the algorithm of each module.

3 Graphically illustrate the invocation relationship between procedures or functions4 Make a list of programs with necessary comments.

5. What is a better solution to the design topic?

6 What are the gains and experiences through this design?

3. Design methods and basic principles.

1 Problem Description:

Since 100! The result cannot be accurately described by a variable of a certain data type in C++, so a large array is needed where each element stores a single digit, so that a very large number can be represented by a large array.

2 Solution to the problem:

According to the problem description, you can use the process of multiplication by the simulator to calculate 100! value. First, use a large array to describe the decimal number 1, and then let the number represented by the large array be the value of the large array multiplied by 2; Let the number represented by this large array be the value of this large array multiplied by 3; ...And so on until the number represented by this large array is the value of this large array multiplied by 100.

This gives you 100! value.
