BLOT: C++ has implicit conversion, I am looking for a way to prevent it.
Let me take an example for the same, for the code snippet below:
#include <iostream>
int incrementByOne(int i) {
return ++i;
}
int main()
{
bool b = true;
std::cout << incrementByOne(b) << std::endl;
return 0;
}
It would output: 2
How can I prevent such implicit conversions and be strict about taking only int as an argument even at runtime?
One way I can think of is overload the function. So the new code would look like:
#include <iostream>
int incrementByOne(int i) {
return ++i;
}
int incrementByOne(bool) {
std::cerr << "Please provide integer as argument" << std::endl;
exit(0);
}
int incrementByOne(char) {
std::cerr << "Please provide integer as argument" << std::endl;
exit(0);
}
int main()
{
bool b = true;
std::cout << incrementByOne(b) << std::endl;
return 0;
}
Is there any other(recommended) way of preventing implicit conversions at runtime?
