Bug ID: 120942
Summary: internal compiler error happend when i lose include
some file
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: q1210081098 at gmail dot com
Target Milestone: ---
After running the following code, I received an internal compiler error. I know
this is due to the lack of # include<vector>, but it outputs an gcc error
```
#include <iostream>
#include <string>
#include <map>
#include <numeric>
int main() {
std::map<std::string, std::vector<int>> gradebook;
// Add students and their grades
gradebook["John"] = {85, 90, 77};
gradebook["Emily"] = {95, 88, 100};
gradebook["Michael"] = {88, 92, 100};
// Calculate the average grade for each student
for (const auto& student : gradebook) {
double average = std::accumulate(student.second.begin(),
student.second.end(), 0.0) / student.second.size();
std::cout << "Average grade for " << student.first << ": " << average
<< "\n";
}
return 0;
}
```
the output is
```
