Sure! Here's the C++ code to solve this problem:
```cpp
#include <iostream>
int main() {
int totalStudents, chineseGroup, mathGroup, bothGroups;
std::cout << "Enter the total number of students: ";
std::cin >> totalStudents;
std::cout << "Enter the number of students in the Chinese interest group: ";
std::cin >> chineseGroup;
std::cout << "Enter the number of students in the Math interest group: ";
std::cin >> mathGroup;
std::cout << "Enter the number of students in both groups: ";
std::cin >> bothGroups;
int neitherGroup = totalStudents - (chineseGroup + mathGroup - bothGroups);
std::cout << "The number of students who didn't join either group: " << neitherGroup << std::endl;
return 0;
}
```
Please replace the placeholder values (`totalStudents`, `chineseGroup`, `mathGroup`, `bothGroups`) with the actual numbers provided in the problem statement.
