Thread: dynamically defined array size in a function

I'm writing a function to read in a number of words from a binary file. the size of each word and the number of words to be read are defined by the function input parameters. I cannot allocate the size of the array to contain all th words properly.

Code:

void ReadSW01HEAD(FILE *ptr, long n /*Number of Parameters*/, long Size /*Section Size*/)
{
	char Param[n];
	int FieldLength = Size/n; 
	
	printf("Parameters Present\n\n");

	fread(&Param,sizeof(char),FieldLength,ptr);
	printf("%s   ",Param);
}

Do I need a pointer of some sort?
