Why this shows no output just by replacing x =name instead of name = x in this code ?

Question

#include <iostream>
using namespace std;

class myClass {
public:
myClass(string nm) {
setName(nm);
}
void setName(string x) {
name = x;
}
string getName() {
return name;
}
private:
string name;
};

int main() {
myClass ob1("David");
myClass ob2("Amy");
cout << ob1.getName();
}

Answer 1

And why would it show any value? You wanna assign name to x, where x is destroyed at the end of a function scope.
