file reading line by line

i have to read from the file all the data before ' : ' and then omit the current and go to the next line and read the data.
e.g.

Numbers:
1, 2, 3;
Font:
6, 7, 8;



and i have got the first 2 lines and no luck with the last 2.


File.getline(temp,200,':');

strcpy(temp2,"Numbers");
if (strcmp(temp,temp2)==0)
{
File.getline(temp,200,';');
int i=0;
char* token;
int buffer[200];
token = strtok( temp, ",;");
while( token != NULL )
{
buffer[i]=i;
token = strtok( NULL, ",;");
i++;
}

alphabets= new int[i];

for(int j=0;j<i;j++)
{
alphabets[j]=buffer[j];
}

numAlphabets=i;
}

strcpy(temp2,"Font");
if (strcmp(temp,temp2)==0)
{
File.getline(temp,200,';');
int i=0;
char* token;
char buffer[200];
token = strtok( temp, ",;");
while( token != NULL )
{
buffer[i]=i;
token = strtok( NULL, ",;");
i++;
}
states= new int[i];
for(int j=0;j<i;j++)
{
states[j]=buffer[j];
}
numStates=i;
}

Code:

---

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



int main()
{
        string findThis;
    string one;
        string item;
        vector<string> v;
        int iii;

        ifstream in("file.txt");

        while(!in.eof())
        {

                getline(in, item);
                iii = item.find(":");
                item.erase(iii, item.size() - iii);
                one = one + item + "\n";
               
        }

        cout << one << endl; // this should cout out all of the lines
                            // ending before the :

}
