what's wrong in my code, please give me some test

#include <iostream>
#include <vector>
#include <string>
#include <map>
using namespace std;

map<string,string>functions;
map<string,string>variables;

int main(){
int count_function, count_variable,i,j;
string line,s1,s2,s, type;
cin >> count_function;
for(i = 0; i < count_function; i ++){
cin >> s1;
while(cin >> s){
if(s == ":") break;
s1 = s1 + " " + s;
}
cin >> s2;
functions[s1] = s2;
}

cin >> count_variable;

vector<string>variable;
vector<string>types;

for(i = 0; i < count_variable; i ++){
cin >> type >> s >> s1 >> s1;
while(s1[s1.size() - 1] != ')'){
cin >> s2;
s1 = s1 + " " + s2;
}
if(variables.find(s) == variables.end()){

s2 = "";
j = 0;
while(s1[j] != '(') s2 += s1[j++];  s2 += '('; j ++;
while(s1[j] != ')'){
line = "";
while(s1[j] != ',' && s1[j] != ')') line += s1[j++];
if(variables.find(line) == variables.end()){
cout << "Error on line " << i + 1 << ": " << "Unknown variable" << endl;
return 0;
}
s2 += variables[line];
if(s1[j] == ','){
s2 += ", ";
j += 2;
}
}
s2 += ')';

if(functions.find(s2) == functions.end()){
cout << "Error on line " << i + 1 << ": " << "No such function" << endl;
return 0;
}

s2 = functions[s2];

if(type == "auto"){
variable.push_back(s);
types.push_back(s2);
type = s2;
}
if(type != s2){
cout << "Error on line " << i + 1 << ": " << "Invalid initialization" << endl;
return 0;
}
variables[s] = s2;
}else{
cout << "Error on line 2: Double declaration" << endl;
return 0;
}
}
for(i = 0; i < types.size(); i ++) cout << variable[i] << " : " << types[i] << endl;
