Can anyone help me find a program written in C, at least 500 lines or more, without pointers, urgent

Make a bank account management system.

You don't need to specify how many lines you want to start with, and the requirements are added slowly.

Make a student registration management system, anyway, you will benefit from writing more, right?

1 Give you two of them all, and you can choose for yourself.

1.Print the Yang Hui triangle with C programming. The format is as follows: (up to line 10) 11 1

Source: include

#include

using namespace std;

void main()

Use an array to store five colors.

int i,j,k,n(0);

for(i=0;i<3;i++)

Output type and color}}

cout<<"Take the French Communists"<

#include

using namespace std;

class date;

void date::setdate(int y,int m,int d)

void date::print()

int date::isleapyear()void main()

elsecout<<"Not a leap year"<} This is the procedure for judging leap years, written by yourself!

C++ is a language that requires manual manipulation of memory, and pointers are addresses that point to a certain memory. It's OK to look for this gfw book and take a look,

It can effectively represent complex data structures; Ability to dynamically allocate memory; convenient use of strings; Efficient and convenient use of arrays; More than 1 result can be obtained when calling the function; It can directly handle memory unit addresses, etc.

Pointing is dangerous for beginners, and it is more recommended to use references, and you can also use containers to automatically manage memory, such as vector list maps, etc.

In C, a pointer variable is used to point to a file, and this pointer is called a file pointer. A file pointer allows you to perform various operations on the file it refers to.

The general form of a pointer to a defined documentation file is:

file *pointer variable identifier; （fp）

The advantage of pointers is that they manipulate memory directly, which is fast and direct.

The downside is dangerous, very dangerous! Something that only the best uses!

Writing programs is often used by people who are generally doing software development.

2: null, case. If you encounter null, you should first figure out when null will occur instead of a simple protection decision. Probably, by design, it certainly can't be null here

3: The second category is to find the place where the pointer is modified, and determine that there is a problem according to the existing logic. Generally empirical stuff. For example, memory copy, string operations, etc.

The validity of the pointer can only be determined whether it is empty or not. Therefore, after definition, free must be assigned a null value.

Uninitialized or free, after pointing to null, you have to judge you as such.

Suppose your pointer is defined as int *a;

if(*a == null)

You can test it out with this!!

Good habits are the most important.

Initialize to null immediately when defined

is also assigned to null immediately after free

Then you'll be in the middle of the program.

good luck

There's nothing you can do, it's all up to you to code.

For example, pointer variable initialization, pointer assignment null after free, etc.

Try exception or call platform-specific APIs.

It's easy to do with qt, and qt has a similar demo

It's so simple that I don't want to use my brain to think about it.
