Problem with a code (newbie)

Question

i wrote this program to collect students marks and names , the problem is , when i run it it skips the name typing part ( getline(cin, name) ) , here's the code :

#include <iostream>
#include <string>

using namespace std;

int main()
{
float m[6];
int r;
int x,a=1;
string n[6];
string name;

while(a==1) {

cout << "Enter the student's number : " << endl;
cin >> r ;
cout << "\nType his full name : " << endl;
getline(cin, name) ;
n[r] = name ;
cout << "\nType in his mark : " << endl;
cin >> m[r] ;
cout << "\n \n The student number : " <<r<< "\n Name : " << n[r] <<"\n Mark : " << m[r] << endl;

cout <<"Enter another student's mark ? \n 1-Yes \n 2-No " << endl;
cin >> a ;

}

cout << "The classroom's Marks are : " << endl;

for (x=0;x<6;x++) {
cout << n[x] << " NR : "<<x<<" Mark : " <<m[x]<< endl;
}
return.0;
}

Answer 1

I'm running it on code blocks

Answer 2

I replaced the (getline(cin, name)) by cin >> n[r] to directly assign the string to the n array and it worked it gave me the option to write but only words when i wrote 2 words or more . The program skips all the other inputs .
I don't know what caused this . But i think shouldn't have used both a string and integer array in the same function .
