Write a more generalized format() function that works like this: double amt = 1234.25; cout << format(amount); // default formatting cout << format(amount, .2); // fixed, 2 decimals cout << format(amount, 12.2); // width 12, fixed, 2 decimals cout << format(amount, 12.2, "€"); // width 12, fixed, 2 decimals, Euro file: #include // fixed #include // setw, setprecision #include // ostringstream #include #include // round using namespace std; #include "format.h" string format(double amt, double fmt, const string& prefix) { } In the lecture, you worked on the toDollars function which formats a number in the form $ 1,234.25. Write a more generalized format() function that works like this: double amt = 1234.25; cout << format(amount); // default formatting cout << format(amount, .2); // fixed, 2 decimals cout << format(amount, 12.2); // width 12, fixed, 2 decimals cout << format(amount, 12.2, "€"); // width 12, fixed, 2 decimals, Euro Complete the following file: format.cpp 1 2 3 4 5 6 7 8 9 10 11 12 #include // fixed #include // setw, setprecision #include // ostringstream #include #include // round using namespace std; #include "format.h" string format(double amt, double fmt, const string& prefix) { } Use the following files: Tester.cpp #include #include #include #include using namespace std; #include "format.h" int main() { cout << format(1234567.2345678) << endl; cout << "Expected: 1.23457e+06" << endl; cout << format(1234567.2345678, .5) << endl; cout << "Expected: 1234567.23457" << endl; cout << '"' << format(1234.2345678, 10.3) << '"' << endl; cout << "Expected: \" 1234.235\"" << endl; cout << '"' << format(315.25, 8.2, "£") << '"' << endl; cout << "Expected: \"£ 315.25\"" << endl; } format.h #ifndef FORMAT_H #define FORMAT_H #include std::string format(double amt, double fmt = 0.0, const std::string& prefix = ""); #endif
