Hi Experts,

If I want to print something formatted in certain way in C,

printf("%s - %d - %s\n", str1, num, str2);


Is there C++ functions similar to printf for formatted output.  If so, how do I use it?

Just use 'cout' like

cout << str1 << " - " << num << " - " << str2 << endl;

BTW, the equivalent or 'sprintf()' would be a stringstream, e.g. instead of

sprintf(buf,"%s - %d - %s\n", str1, num, str2);
printf("%s",buf);

you'd use

#include <sstream>
using namespace std;

stringstream ss;

ss << str1 << " - " << num << " - " << str2 << endl;
cout << ss.str();
