Reading in an character array from user, segmentation error?

Posted on 2003-11-24

For class we've been assigned to take a file of football players and read them into an array or structures.  Everything is read in correctly, and we are to give the user the option to search through the array of structures to find a player, that is if they are in the list.  

Here's what I have so far.
When this code runs, it says-
Enter the exact name to search for: Segmention Fault
and exits.
Ive been using g++.
int searchName(qbInfo qbs[], int numQBs, int x)
{
int index = 0;
bool found = false;
char userinput[23];
int count = 0;
char ch;

cout << "Enter the exact name to search for: ";
cin.get(ch); //this is where the error is coming in
while(ch!= '\n') // read in until user hits enter
{
userinput[count]= ch;
count++;
cin.get(ch); //going to cause the error again?
};
What can I do to read in the entire name, Ive tried cin >>userinput; but that is only going to read up until say the name is "Trent Green", it will only read in "Trent" and hit the space and stop.

Thanks

Jhoe-Oendus, >> will ignore spaces and end of lines as its default behavior. Looking at your function I see no logical error (are you missing a } to end your function?).
You might want to look into the use of getline.
cin.getline(userinput, 23, '\n');

Well I tried that, and noticed that's not what I wanted to do, I tried switching it over to a string and using cin on that, and Im still getting the Segmentation Fault.  And I checked for missing } and everything seems to be closed.  Any other suggestions?

This was the new code with the string implemented.
int index = 0;
bool found = false;
string userinputx;
char userinput[23];
int count = 0;
char ch;

 cout << "Enter the exact name to search for: ";
 cin >> userinputx;
 cout << "You entered ";
 cout << userinputx;

Thanks

can you post the entire file here? Since from what I see I can't tell that any of these could be giving you a segmentation fault error.
