Question

How to set different values to auto variable (Remember: you cannot change the type) in C++

Answer 1

#include <iostream>

int main() 
{
	auto n = 13;
	std::cout << n << std::endl;

	n = 'Z';
	std::cout << n << std::endl;

	n = 3.14;
	std::cout << n << std::endl;

	// Error: a value of type "const char *" cannot be assigned to an entity of type "int"
	// n = "c++"; 

	return 0;
}

/*
run:

13
90
3
