[ishakarthika]

i have a .txt file which contains line of string like the below format
|111|34 sdddd| ppppp| A/C| 32| sadfd|
|4324|23 mmm| yyyyy| A/C|32| fdfffdfd|

the sixth column is the no of seats column where when i check the status of that particulat bus no 4324 it is displaying that the "seat is not available" and "available seats are 0"

In this code snippet i
i face the above problem in the "temp" variable.
please help me out.





void passenger::transaction(string bus_no,int tkt,string passenger_name,int age,string journey_date,int seat,int totalprice)
{ int temp;
string tempval,token,line;
stringstream iss;
int flag,flag1;
size_t found;
size_t found1;
fstream file("transaction.txt",ios::in);
fstream file1("t.txt",ios::out);
while(getline(file,line))
{
found=line.find(journey_date);

if(int(found)>0)
{
found1=line.find(bus_no);
if(int(found1)>0)
{
iss<<line;
while(getline(iss,token,'|'))
{
tempval=token;
}
temp=atoi(tempval.c_str());
if(temp<seat) {
cout<<"\t\tSorry! Seats Not Available Now.."<<endl;
cout<<"Available Seats are "<<temp<<endl;
}
else if(temp==0)
{
cout<<"Sorry! Seats Fully Booked"<<endl;
}
else
{
temp=temp-seat;
std::string s;
std::stringstream out;
out<<temp;
s=out.str();
line.replace(15,2,s);
cout<<"****Ticket Successfully Booked***"<<endl;

Not sure I understand the problem you're trying to solve. The sixth column of the first two records are " sadfd" and " fdfffdfd". In what way are these strings interpreted as number of seats? The fifth column ("32" and "32") look more appropriate.

By the way, it is helpful to enclose your source code in [code] tags.
