What is the difference between cout and printf ?
I learned using printf and scanf , but in an online course I see the teacher using cout and some pages also use cout , but others use printf ...
Can I replace cout with good old printf ?
In general, you should. cout is C ++, printf() is C. They are completely different, but the goal is the same .
cout is owned by C ++ and is in the iostream header
example:
#include <iostream>
#include <string>
int main(int argc, char* argv[])
{
std::string nome; //String que guardará o valor de nome
//cin equivale á scanf() em C++
std::cin >> nome; //Pega o valor digitado no console e coloca em nome
//cout equivale a printf() em C++
std::cout << nome;
//Outro forma de usar cout
std::cout << "Nome: " << nome << " Idade: " << 10 << "\n";
return 0;
}
