someone help me pls..there 's error from the input..

[Jackie91]

when i enter '1' .. the cout is connected,i cant even input the 1st line,which is the 'name = '.. help me pls.

#include<iostream>
#include<string>

using namespace std;
void main()
{
int input;
int choose;

string name;
string icNum;
string parentName;	
string address;
string TelNum, parentTelNum;


cout << "\n\t\t\t STUDENT REGISTRATION SYSTEM" <<endl <<endl;

cout << "1. ADD" <<endl;
cout << "2. EXIT" <<endl <<endl;
cout << "ENTER OPTION : ";
cin >> input;


switch (input){
case 1:
	cout << "Please Enter Student Name : ";
	getline(cin, name);
	cout << "Student's IC number/passport number: " ;
getline(cin,icNum);
cout << "Student's address: " ;
getline(cin, address);
cout << "Parent's name: " ;
getline(cin,parentName);
cout << "Enter parent's telephone number: " ;
getline(cin,parentTelNum);

cout << "\nYour input was : " <<endl <<endl;
cout << "Student's name: " << name <<endl;
cout << "Student's IC number or passport number : " << icNum << endl;
cout << "Student's address : " << address <<endl;
cout << "Parent's name : " << parentName <<endl;
cout << "Parent's telephone number : " << parentTelNum << endl <<endl;

cout << "Press 1 - Re-enter particular" <<endl;
cout << "Press 2 - Confirm that the student's particular is correct" << endl;
cout << "Options : ";
cin >> choose;

break;

default:
cout << "Thank you " <<endl;


}

}

I'd suggest consistency when programming.

Instead of

int input;
cin >> input;

switch(input)
{
case 1:
//...
break;
}

try getline with string and converting the string to an int using atoi(const char*)

string input;

getline(cin, input);
int option = atoi(input.c_str());

switch(option)
{
case 1:
//...
break;
}

This should work.

You could also include the stringstream header <sstream> and convert it through there

#include <iostream>
#include <string>
#include <sstream>

//.....
string input;
//.....
getline(cin, input);

//put input to stringstream
stringstream ToInt(input);

int option;
ToInt>>option; //put the value in an integer

switch(option)
{
case 1:
//...
break;
}

There's an extra '\n' (newline) in the stream (from when you press enter after the number) that's being taken in by the first getline as a signal that input has ended. So it's getting skipped. ShadowScripter's idea is correct and probably preferable (though you could use stringstreams as well) but an alternate would be to put a cin.ignore() before your getline statement to sop up that extra '\n' .

wow...thanks so much guys..
ur great..

Indeed, I was just editing my post adding stringstream to the equation, since its easy and safe.
A good example is in fact cin.ignore(), its simple to use and would get rid of that horrible new line issue.
The '/n' character usually pops up when combinating cin>>var and getline(cin, var) which is the case.

#include<iostream>
#include<string>

using namespace std;
void main()
{
int input;
int choose;

string name;
string icNum;
string parentName;
string address;
string TelNum, parentTelNum;


cout << "\n\t\t\t STUDENT REGISTRATION SYSTEM" <<endl <<endl;

cout << "1. ADD" <<endl;
cout << "2. EXIT" <<endl <<endl;
cout << "ENTER OPTION : ";
cin >> input;

//eliminating terminating character in stream
cin.ignore(); 


switch (input){
case 1:
	cout << "Please Enter Student Name : ";
	getline(cin, name);
	cout << "Student's IC number/passport number: " ;
	getline(cin,icNum);
	cout << "Student's address: " ;
	getline(cin, address);
	cout << "Parent's name: " ;
	getline(cin,parentName);
	cout << "Enter parent's telephone number: " ;
	getline(cin,parentTelNum);

	cout << "\nYour input was : " <<endl <<endl;
	cout << "Student's name: " << name <<endl;
	cout << "Student's IC number or passport number : " << icNum << endl;
	cout << "Student's address : " << address <<endl;
	cout << "Parent's name : " << parentName <<endl;
	cout << "Parent's telephone number : " << parentTelNum << endl <<endl;

	cout << "Press 1 - Re-enter particular" <<endl;
	cout << "Press 2 - Confirm that the student's particular is correct" << endl;
	cout << "Options : ";
	cin >> choose;
        cin.ignore();

break;

default:
cout << "Thank you " <<endl;


}

I didn't even notice it before but never use void main() main() always returns an int according to the standard.
