hi, i got a problem here, my a prints 53 no matter what extensions i type instead of a negative number.. can anyone tell me how to overcome it??

When i enter a.csv it gives me the 0, however i need to allow user to specify the drives when i enter c:\a.txt it gives me 53, when i enter c:\a.csv it also prints 53

I don't think you understand what strpbrk does. It returns the location of the first character it finds so it will return the first '.' or the first 'c' or the first 's' or the first 'v' that it finds. In "c:\a.txt", c is the first character found. Use strstr().

Hey thanks, heres the correct code.. cheers

do{
			printf("Enter the full file path that you would like to save the file to \n");
			printf("e.g. C:\\Temp\\Employee.csv\n");
			printf("NOTE THE .CSV EXTENSION\n\n");

			gets(fileName);

	
			if(strstr(fileName, ".csv" )== NULL)
				printf("Invalid file extension\n\n");


	}while(strstr(fileName, ".csv" )== NULL);

gets is very unsafe. Recommend you try fgets instead.
