c++ - I can't understand why my output is 1,1 how can I change it to "type name" and "parameters"? TIA -

i'm new @ c++ , i'm reading functions i'm trying use string can't understand it. how can show "type name" , "parameters" in output? here's code:

#include <iostream> using namespace std;  string f1 (string a) {     string b;     b = " type name ";     return (b); }  string f2 (string c) {     string d;     d = " parameters ";     return (d); }  int main () {     string x,y;     x = f1(" type name ");     y = f2(" parameters ");     cout<<"functions group of statements executed"<<endl;     cout<<"when called. consist of"<< x <<","<< y <<endl;     cout<<"and statement. can called some point of program."<<endl;      return 0;    } 

cout<<"when called. consist of"<< f1 <<","<< f2 <<endl; 

f1 , f2 functions. don't want output functions, want output result of calling functions.

x = f1(" type name "); y = f2(" parameters "); 

you have stored result of calls in x , y, use those.

cout<<"when called. consist of"<< x <<","<< y <<endl; //                                            ^         ^
