Thread: Problem with scanf, strings and structure

I am trying to create a gift exchange list generator, but for whatever reason this won't compile. My uncle who programs for a living was unable to find a problem with it. Here is what I got at the moment..

Code:

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


int main (int argc, const char * argv[]) {
	
	
	int NumPeople;
	int i;
	int RandNum;

	typedef struct _Names
	{
		char fromname[20];
		char toname[20];
		
	} Names[100];
	
    printf("How many people you would like on your list.\n");
	scanf("%d", &NumPeople);
	
	if ( NumPeople > sizeof(Names)) 
	{
		printf("cannot have more than %d entries\n", sizeof(Names) );
		return 20;
	}
	
	for (i = 1; i <= NumPeople; i++)					
	{
		printf("Enter name number %d.\n", i);
		scanf("%s", Names[i].fromname );
	}
	
	for (i = 0; i <= NumPeople; i++) 
	{
		RandNum = rand() % NumPeople + 1;
		if ( 0 != strcmp(Names[i].fromname, Names[RandNum].fromname ))
		{
			strcpy( Names[i].toname, Names[RandNum].fromname);
		}
	}
	for (i = 0; i <= NumPeople; i++) 
	{
		printf("%s -> %s\n", Names[i].fromname, Names[i].toname);
    }
	return 0;
}

Thanks for the reply. I guess he had a few to many drinks tonight and missed that one. I am new to using structures and need to figure out exactly what is happening.
