multi-dimensional arrays

I am trying to learn multi-dimensional arrays in C/C++, but am not having much luck. I think I understand the way this type of array works, but I am having problems.

Code:

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

#define MAX_NAME_COUNT 10
#define MAX_NAME_LEN 100

int	main(){
	char	*names[MAX_NAME_COUNT][MAX_NAME_LEN];
	int	x;

	printf("enter the names of 10 people:\n");

	for(x = 1; x < MAX_NAME_COUNT; x++){
		scanf("%s", names[x][0]);
	}

	printf("these are the names you entered are:\n");

	for(x = 1; x < MAX_NAME_COUNT; x++){
		printf("%s\n", names[x][0]);
	}

	return;
}

Does anyone know what is wrong in my code? There are no compilation errors, but the program crashes after the first name is entered.

The array should not be an array of char*, but of just char. (And the scanf and printf should just be names[x], not names[x][0].)

Code:

char	*names[MAX_NAME_COUNT][MAX_NAME_LEN];

which declares a 2D array of pointers to char, should be:

Code:

char	names[MAX_NAME_COUNT][MAX_NAME_LEN];

which declare an array of (allocated) strings.

Code:

scanf("%s", names[x][0]);

should be:

Code:

scanf("%s",names[x]);

as names[x][0] is only the 1st character of the xth string. You should also make sure scanf does not overrun the allocated space.

Code:

printf("%s\n", names[x][0]);

same thing here, this should be names[x] only.

There are no compilation errors, but the program crashes after the first name is entered

You were using unallocated memory.

Also note that you generally want for loops to start at 0 and count upwards, instead of at 1. array[0] is a valid element, after all, and if you start at array[1] you've wasted an entire element.

Note that the last two are resources that should explain WHY your previous code won't work.
Root4 is providing you with correct code (save for the scanf vulnerability).
