You'd need to open a stream to the file using ifstream fs(filename)
Then you would do something along these lines:

int lineNum = 0;
string line;
string correctPhoneNumber;
while(getline(fs,line))
{
    if(line == company)
    {
         getline(fs, correctPhoneNumber);
         cout << "The company's number is "<< correctPhoneNumber << " found at line " << (lineNum+1);
         break; 
    }
    lineNum++;
}

The method I've given is based on how your addNumber worked. Personally I'd have company name and number on the same line separated by a ';' rather than having them on separate lines.

Also avoid using system, it's generally not good practice: http://www.cplusplus.com/articles/j3wTURfi/
