目前我有一个字符串" {201,23,240,56,23,45,34,23}"它频繁地改变了b $ b（可能是3Hz）。这些数字可以是任何数字，其中
小于4位数。我想把这个字符串放在一个
数组中，以便我可以用于某些计算目的。我已经通过不同的可能性来查看
，其中一个将涉及
广泛的字符串比较，atoi（），附加到数组类型
算法。然而我意识到，当我们输入数组时，c ++以与上面相同的形式接受它，然后我想是否可以模拟c
++输入此字符串时一个数组。
我不知道从哪里开始。
谢谢，

Currently I have a string "{201,23,240,56,23,45,34,23}" which changes
frequently (possibly at 3Hz). The numbers can be any number having
less than 4 digits. I want to take this string and place it in an
array so that I can use for certain computational purposes. I''ve
looked through different possibilities one of which would involve an
extensive string comparison, atoi(), append to array sort of
algorithm. However I realized that when we input arrays c++ accepts it
in the same form as above and then I thought whether I could simulate c
++ input this string when asked for an array.
I don''t know where to start.
Thanks,
Sudzzz

是的，你可以模拟C ++输入，它会涉及一些角色
比较，atoi（或strtol，更喜欢它），附加到数组，类似于
算法。您认为编译器如何做到这一点？
Yes, you can simulate C++ input, and it will involve some character
comparison, atoi (or strtol, more like it), append to array, sort of
algorithm. How do you think the compiler does that?
我不知道从哪里开始。
I don''t know where to start.
从这里开始：
#include< string>
#include< vector> ;
#include< cassert>
int main（）{
std :: string mystring（" {201 ，23,240,56,23,45,34,23}"）;
std :: vector< intvint;
//编写要提取的代码来自''mystring''的数字
//并将它们放入''vint''
断言（vint.size（）== 8） ;
断言（vint [0] == 201）;
断言（vint [1] == 23）;
断言（vint [2] == 240）;
断言（vint [3] == 56）;
断言（vint [4] == 23）;
断言（vint [5] == 45）;
断言（vint [6] == 34）;
断言（vint [7] == 23）;
}

Start here:
#include <string>
#include <vector>
#include <cassert>
int main() {
std::string mystring("{201,23,240,56,23,45,34,23}");
std::vector<intvint;
// write code to extract numbers from the ''mystring''
// and place them into ''vint''
assert(vint.size() == 8);
assert(vint[0] == 201);
assert(vint[1] == 23);
assert(vint[2] == 240);
assert(vint[3] == 56);
assert(vint[4] == 23);
assert(vint[5] == 45);
assert(vint[6] == 34);
assert(vint[7] == 23);
