Handling permissions and errors in C++ is a critical part of developing robust applications. Proper error handling ensures that your application can respond appropriately to unexpected situations, while managing permissions helps to control access levels to different parts of your program or system.

This article discusses how to effectively handle permissions and errors in C++ applications, providing guidance on best practices and common techniques.
// Example of error handling in C++
#include
#include
void checkAccess(int userRole) {
if (userRole < 1) {
throw std::runtime_error("Access Denied: Insufficient permissions.");
} else {
std::cout << "Access Granted!" << std::endl;
}
}
int main() {
try {
int userRole = 0; // Example role; 0 means no access
checkAccess(userRole);
} catch (const std::runtime_error& e) {
std::cerr << e.what() << std::endl; // Handle the error gracefully
}
return 0;
}
