This question already has an answer here:

• Issue with cin when spaces are inputted, using string class 2 answers

#include<iostream>
#include<string.h>
#include<conio.h>
#include<stdio.h>
using namespace std;
class Student{
private:
    char name[20];
    float marks;
    float percentage;
    int rollNo;
public:
    void read_data(){
    char *p;
    cout<<"Enter Name: ";
    cin>>name;

    fflush(stdin);
    cout<<"Enter Roll Number: ";
    cin>>rollNo;
    cout<<"Enter Total Marks Of 5 Subjects: ";
    cin>>marks;
   }
   void display_data(){
   cout<<"Name: "<<name<<endl;
   cout<<"Roll Number: "<<rollNo<<"\n";
   cout<<"Marks: "<<marks<<"\n";
   cout<<"Percentage Computed: "<<percentage<<"\n\n";
   }
   void compute_data(){

   percentage = marks/ 5;

   }

};
int main(){
Student s[3];
int i=0;
 for(i=0;i<=2;i++){
    s[i].read_data();
    s[i].compute_data();
    }
for(i=0;i<=2;i++){

    s[i].display_data();

}

getch();
}

how can I get the full name in the output? why 'name' variable is not storing the full name i.e "Tushar Rawat"?what are the different ways to resolve this problem in c++11?? please tell me As soon as possibleenter image description here
