Question

how to print variable from value of other variable in c++
i’m just new in c++.

in php we can make/print a variable by the value of other variable.
like this.

$example = 'foo';
$foo = 'abc';
echo ${$example}; // the output will 'abc'

how can i solve this in c++?

Looking at it another way, it’s just indirection, which C++ uses extensively. An analogous example in C++ might be…

using namespace std;
string foo = "abc";
string* example = &foo;
cout << *example << endl;  // The output will 'abc'

…or using a reference instead of a pointer…

using namespace std;
string foo = "abc";
string& example = foo;
cout << example << endl;  // The output will 'abc'
