C- reading from file into a dynamic alloc array (using realloc)

[Despairy]

i studied c++ before c guess that was my mistake...

i try to read from a file a set of strings and put them
in the new allocated array, i do not understand what is the main thing this
code isnt working. i get segmentation fault...
and even trying to input a character in the array will result in seg fault.

(u call the program with 2 file names and first will be for input
and 2nd for output)

thanks

#include "ex1.h"

void error(char *msg);
void checkFiles(int argc, char *argv[], FILE * *in,FILE * *out);

					
int main(int argc, char *argv[]) {
	
	FILE *inFile;
	FILE *outFile;
	
	checkFiles(argc, argv,&inFile,&outFile);
	
	int numOfStrings=0;	
	int sizeOfList=0;
	
	char myString [MAX_STR_LEN];
	int sortBy;
	
	puts("Enter 0 for sort by NAME or 1 for sort by ID");

	scanf("%d",&sortBy);

	char** nameList;
	int d;//TESTS

	while(fgets (myString , MAX_STR_LEN , inFile) != NULL) 
	{
		numOfStrings++;
		if (sizeOfList==0)
			sizeOfList++;
		else
			sizeOfList*=2;
		
		if (numOfStrings==1)
		{

				nameList=realloc(nameList,sizeOfList*(sizeof(char**)));
		
				if (nameList==NULL)
					error("Can't allocate memory1");
		
				nameList[0]=(char*)malloc(sizeof(char));
				
				if (nameList[0]==NULL)
					error("Can't allocate memory2");
		
				strncpy(nameList[0],myString,sizeof(myString));
		
		
			}
			else
			{
		
										scanf("%d",&d);
				nameList=realloc(nameList,sizeOfList*(sizeof(char**)));	
										scanf("%d",&d);
				if (nameList==NULL)
					error("Can't allocate memory3");
				scanf("%d",&d);
				nameList[numOfStrings]=(char*)malloc(sizeof(char));
				if (nameList[numOfStrings]==NULL)
						error("Can't allocate memory4");
						scanf("%d",&d);
				strncpy(nameList[numOfStrings],myString,sizeof(myString));
						scanf("%d",&d);
		}
		
	}

	nameList[0][0]='1'; why even this wont work?
	int i=0;
	scanf("%d",&d);
	printf("%c",nameList[0][0]);
	scanf("%d",&d);
	for (;i<numOfStrings;i++)
		fputs(nameList[i],outFile);
	
	
	fclose(inFile);
	fclose(outFile);
	return 0;
}

nameList is uninitialized. Since you're always using realloc() to allocate memory to nameList, it should be initialized to NULL for the first allocation to succeed:

char** nameList = NULL;
