Who can fix this big C++ code?

#include <fstream>
#include <iostream>
#include <string>
#include <map>
#include <vector>
#include <math.h>
#define println(x,y) if(y){cout<<x<<endl;}else{cout<<x;}
using namespace std;

class Iggy{
public:

  Iggy(){};

  void createVar(string name,vector<string> val){
    vars["$"+name] = val;
  };

  void createVar(string name,string val){
    vars["$"+name] = val;
  };

  void writef(string ln){
    println(ln,false)
  };

  void writeln(string ln){
    println(ln,true);
  };

  vector<string> getVar(string name){
    return vars[name];
  };

  void createFunc(string name,vector<string> params){
    funcs[name] = params;
  }

  void createFunc(string name){
    funcs[name] = "void";
  };

private:
  map<string,vector<string>> vars,funcs;
}

int main(){
  ifstream f("main.iggy");
  string l;
  Iggy i;
  while(getline(f,l)){
    try{
      //----------------------
      if(l == l.substr(0,l.find(" = "))+" = "+l.substr(l.find(" = ")+3)){
        i.createVar(l.substr(0,l.find(" = ")),l.substr(l.find(" = ")));
      };
      //----‐-----------------
      if(l == "writef "+l.substr(7)){
        i.writef(l.substr(7));
      };
      //---------------------
      if(l == "writeln "+l.substr(8)){
        i.writeln(l.substr(8));
      };
      //---------------------
      if(l == "getline $"+l.substr(9)){
        string *a = new string(" ");
        cin >> a;
        i.createVar(l.substr(8),a);
        delete a;
      };

Hey, is it because you missed the semicolon after print line here?

void writef(string ln){
    println(ln,false)
  };

PS: i do not know c++ so this may be wrong. Someone can correct me in that case…

what is the output of the program supposed to be try this code:

#include <fstream>
#include <iostream>
#include <string>
#include <map>
#include <vector>
#include <math.h>

#define println(x, y) if (y) { cout << x << endl; } else { cout << x; }
using namespace std;

class Iggy {
public:
    Iggy() {};

    void createVar(string name, vector<string> val) {
        vars["$" + name] = val;
    };

    void createVar(string name, string val) {
        vars["$" + name].push_back(val);
    };

    void writef(string ln) {
        println(ln, false);
    };

    void writeln(string ln) {
        println(ln, true);
    };

    vector<string> getVar(string name) {
        return vars[name];
    };

    void createFunc(string name, vector<string> params) {
        funcs[name] = params;
    }

    void createFunc(string name) {
        funcs[name] = vector<string>();
    };

private:
    map<string, vector<string>> vars, funcs;
};

int main() {
    ifstream f("main.iggy");
    string l;
    Iggy i;
    while (getline(f, l)) {
        try {
            //----------------------
            if (l == l.substr(0, l.find(" = ")) + " = " + l.substr(l.find(" = ") + 3)) {
                i.createVar(l.substr(0, l.find(" = ")), l.substr(l.find(" = ") + 3));
            };
            //---------------------
            if (l == "writef " + l.substr(7)) {
                i.writef(l.substr(7));
            };
            //---------------------
            if (l == "writeln " + l.substr(8)) {
                i.writeln(l.substr(8));
            };
            //---------------------
            if (l == "getline $" + l.substr(9)) {
                string a;
                cin >> a;
                i.createVar(l.substr(8), a);
            };
            //---------------------
        }
        catch (out_of_range e) {};
    };
    f.close();
    return 0;
}

hello @NataliaKazakiev . Welcome to the forums!

I have corrected the code for you:

#include <fstream>
#include <iostream>
#include <string>
#include <map>
#include <vector>
#include <math.h>
#define println(x,y) if(y){cout<<x<<endl;}else{cout<<x;}
using namespace std;

class Iggy {
public:
  Iggy(){};

  void createVar(string name, vector<string> val) {
    vars["$"+name] = val;
  };

  void createVar(string name, string val) {
    vars["$"+name] = val;
  };

  void writef(string ln) {
    cout << ln;
  };

  void writeln(string ln) {
    cout << ln << endl;
  };

  vector<string> getVar(string name) {
    return vars[name];
  };

  void createFunc(string name, vector<string> params) {
    funcs[name] = params;
  }

  void createFunc(string name) {
    funcs[name] = vector<string>{"void"};
  };

private:
  map<string,vector<string>> vars, funcs;
};

int main() {
  ifstream f("main.iggy");
  string l;
  Iggy i;
  while(getline(f, l)) {
    try {
      if(l == l.substr(0, l.find(" = "))+" = "+l.substr(l.find(" = ")+3)) {
        i.createVar(l.substr(0,l.find(" = ")),l.substr(l.find(" = ")+3));
      };

      if(l == "writef "+l.substr(7)) {
        i.writef(l.substr(7));
      };

      if(l == "writeln "+l.substr(8)) {
        i.writeln(l.substr(8));
      };

      if(l == "getline $"+l.substr(9)) {
        string a;
        getline(cin, a);
        i.createVar(l.substr(8), a);
      };
    } catch(out_of_range e) {};
  };
  f.close();
}

your code still shows the error

7

.

Are you using chatgpt again?

8

It works. Thanks, chatgpt!

9

No, its just that I have gwammar.
Because I am trash at C++ so grammar saves me.

10

Yes, you’re trash using chatgpt only to create good grammars. Bat mai gramars is eksilent!

Anyway, your code has only 1 error, very small error what I have already fixed only for 1 minute.
