'_snprintf': is not a member of 'std'

`_snprintf` is not a member of the `std` namespace. It is a function that is specific to Microsoft's compiler and is used for safe string formatting. If you are encountering this error, it means that you are trying to use `_snprintf` in a context where it is not available.
If you are using a different compiler or platform, you can consider using the standard `snprintf` function instead, which should be available in the `stdio.h` header file. `snprintf` provides similar functionality to `_snprintf` and is portable across different platforms.
Here's an example of how you can use `snprintf`:
```cpp
#include <stdio.h>
int main() {
char buffer[100];
int n = 42;
snprintf(buffer, sizeof(buffer), "The number is: %d", n);
printf("%s\n", buffer);
return 0;
}
```
This code will format the number `42` into the `buffer` array using `snprintf` and then print it using `printf`.
