I am fairly new to C and am getting stuck with arrays and pointers when they refer to strings. I can ask for input of 2 numbers (ints) and then return the one I want (first number or second number) without any issues. But when I request names and try to return them, the program crashes after I enter the first name and not sure why.

In theory I am looking to reserve memory for the first name, and then expand it to include a second name. Can anyone explain why this breaks?

Thanks!

#include <stdio.h>
#include <stdlib.h>



void main ()
{
    int NumItems = 0;

    NumItems += 1;
    char* NameList = malloc(sizeof(char[10])*NumItems);
    printf("Please enter name #1: \n");
    scanf("%9s", NameList[0]);
    fpurge(stdin);

    NumItems += 1;
    NameList = realloc(NameList,sizeof(char[10])*NumItems);
    printf("Please enter name #2: \n");
    scanf("%9s", NameList[1]);
    fpurge(stdin);

    printf("The first name is: %s",NameList[0]);
    printf("The second name is: %s",NameList[1]);

    return 0;

}
