string and array problem

darrenbkl — Wed, 04 Mar 2009 16:14:01 +0800

CODE

#include<iostream>
#include<cstring>
#include<string>
using namespace std;

class student
{
public:
char name[100],grade;
};

bool get_data(student& stu);
void display_data(student& stu);

int main(int argc , char*argv[])
{
const int max=10;
student stu[max];
int i=0,j;

cout<<"Enter student names and grades.[\"Exit\" to quit program]"<<endl;

while(get_data(stu[i]) && (i<max))
{
i++;
}

cout<<endl<<"Entries"<<endl;
for(j=0;j<i;j++)
{
display_data(stu[j]);
}
return 0;
}

bool get_data(student& stu)
{
cout<<endl<<"Enter student name : ";
cin>>stu.name;
if(strcmp(stu.name,"exit")==0)
{
return false;
}

cout<<"Enter student grade : ";
cin>>stu.grade;
return true;
}

void display_data(student& stu)
{
cout<<"Student name : "<<stu.name<<endl;
cout<<"Student grade : "<<stu.grade<<endl<<endl;
}

This program basically prompt user to enter student name and grade.then print the result.
But the problem is using char array,i can't enter name with spaces like John Petrucci. I can only enter single name like David. Should I use string variable in this program?If so,how should i use it?as I don't know much about string.
THX.
