To convert capital letters to lowercase in C++, you can use the tolower() function from the <cctype> library. Here is an example code snippet:
```cpp
include
include
int main() {
char character = 'A';
char lowercase = std::tolower(character);
std::cout << "Lowercase: " << lowercase << std::endl;
return 0;
}
```
This code will convert the character 'A' to lowercase 'a'.
