这是一个小学数学出题器,但是VS运行时提示代码有错误,有人能帮助解决吗?
这是CHATGPT给出的代码。
用的编译器是VS2022,出现的问题包括但不限于:

1:    应输入预处理器指令
2: 应输入标识符
3: 语法错误
4:等等等等 等等等等

你的问题是什么?你不讲出来的话,别人无法改

从 ChatGPT 给出的代码来看,撇明显地错误不谈,逻辑上也不通顺。
vector<string> carry_add(int num) 是产生 num结果在 [0,num-1] 区间的加法。逻辑不同的地方是:数量 与 范围 竟然用了同一个参数;
vector<string> carry_sub(int num) 是产生 num被减数在 [0,num-1] 区间的减法。同上;
vector<string> random_carry_add_sub(int num) 代码缺失,我怀疑应当是 int c = rand() % 2;,但这个函数存在的意义是什么我想不通;
……
函数 generate_pdf 与 generate_xlsx 就有点儿搞笑了,仅仅改了个扩展名。

版主大人都说不通,那这个3.0版本的AI应该是I的有限,暂时不够适用了,还得靠人脑呐!

我确实被这些代码整懵了,感谢版主大人回复,给我脑袋里乱麻给斩断了,不然还得纠结问题出在哪。

这是另一份功能相同的代码,但有一个报错:  void type6_calc(int num1, int num2, int num3, int num4, int type) {    C1075    “{”: 未找到匹配令牌        196行

似乎差一步就能成功运行,我试错后没找到办法解决,不知道是代码本身逻辑问题,还是编译器问题。

你两段代码的功能不相同,那你说一说你具体的需求是什么嘛!
我根据你第一段代码,连蒙带猜:
程序代码:
#include <iostream>
#include <type_traits>
#include <random>
#include <algorithm>
#include <vector>

class foo
{
public:
    foo( std::mt19937& random_gen ) : random_gen_{random_gen}
    {
    }

    struct exp
    {
        unsigned a, b;
        char opt;
    };

    using operation_data_type = std::remove_cvref_t< decltype(exp::a) >;

    exp gen_plus( operation_data_type n ) const
    {
        operation_data_type a = random( n );
        operation_data_type b = random( n-a );
        return { a, b, '+' };
    }

    exp gen_minus( operation_data_type n ) const
    {
        operation_data_type a = random( n );
        operation_data_type b = random( a );
        return { a, b, '-' };
    }

    exp gen_multiplies( operation_data_type n ) const
    {
        operation_data_type a = random( n );
        operation_data_type b = random( n );
        return { a, b, '*' };
    }

    exp gen_divides( operation_data_type n ) const
    {
        operation_data_type c = random( n );
        operation_data_type b = 1 + random(n-1);
        return { c*b, b, '/' };
    }

private:
    operation_data_type random( operation_data_type max ) const // 产生范围 [0,max] 区间的随机数
    {
        return std::uniform_int_distribution<operation_data_type>{0,max}( random_gen_ );
    }

private:
    std::mt19937& random_gen_;
};

int main( void )
{
    // 产生 10条百以内的加法、减法、乘法、除法(对于加减除法而言,是指结果在百以内;对于乘法而言,是指操作数在百以内)
    const size_t range = 100;
    const size_t num_plus = 10;
    const size_t num_minus = 10;
    const size_t num_multiplies = 10;
    const size_t num_divides = 10;

    std::vector<foo::exp> exps;
    exps.reserve( num_plus+num_minus+num_multiplies+num_divides );

    std::mt19937 random_gen{ std::random_device{}() };
    foo f( random_gen );
    for( size_t i=0; i!=num_plus; ++i )
        exps.push_back( f.gen_plus(range) );
    for( size_t i=0; i!=num_minus; ++i )
        exps.push_back( f.gen_minus(range) );
    for( size_t i=0; i!=num_multiplies; ++i )
        exps.push_back( f.gen_multiplies(range) );
    for( size_t i=0; i!=num_divides; ++i )
        exps.push_back( f.gen_divides(range) );
    std::shuffle( std::begin(exps), std::end(exps), random_gen ); // 打乱题目

    // 输出

你这还是几乎什么都没说?

第一操作数的值范围是多少?
第二操作数的值范围是多少?
结果的值范围是多少?
操作符是不是只有加、减两种?
题目必须输出到xlsx这种私有格式吗?如果回答是,那又是一堆的问题...(略)
