How to properly clear stringstream in C++ and prepare it for reuse?
Hello everyone! I'm new to C++ and encountered a problem while working with stringstream. I need to form strings using stringstream in a loop, but after the first iteration it doesn't clear, and data accumulates. Please advise how to properly reset the stringstream state?
Here's my code:
```cpp
#include
#include
#include
int main() {
std::stringstream ss;
for (int i = 0; i < 3; ++i) {
ss << "Number: " << i;
std::string result = ss.str();
std::cout << "Iteration " << i << ": " << result << std::endl;
// Here I'm trying to clear ss, but I don't know how to do it properly
// ss.str(""); // Tried this - doesn't work
}
return 0;
}
```
Output of this code:
```
Iteration 0: Number: 0
Iteration 1:
```
