Thread: trouble with fgets() !

here is my problem! i'm trying to intput a string using fget() method. The problem is it doesn't allow me to do it. Here is what i did:

Code:

#include <stdio.h>


int main()
{
    int coursenumber;
	char coursetitle[50];
	
	printf("Enter Your Course Number:\n");
	scanf("%i", &coursenumber);
	printf("%i\n", coursenumber);
	
	printf("Enter Your Course Titlte:\n");
	fgets(coursetitle, 50, stdin);
    printf("%s", coursetitle);
	
	system("PAUSE");
	return 0;
	
}

i was able to input the course number and print it out, but after i hit enter, it skip the fget() and never give me a chance to input a string, and it end up "Press any key to continue". I have checked exactly what to do when using fget() method to input a string, and i did the same as tutorial in this website.

Is your intent to read in the input as hex? You should use %d specifier if not.

Quick summary:

'%i' : Scan an integer as a signed number. Similar to '%d', but interprets the number as hexadecimal when preceded by "0x" and octal when preceded by "0".

For example, the string "031" would be read as 31 using '%d', and 25 using '%i'.

Hint: You can use "int atoi(char*)" to conver a string (obtained by fgets) to an int. So you avoid mixing scanf and fgets. You can use "int strtoi(char*, char**, int)" like strtoi(string, NULL, 16) to convert the string to a hex

I once worked with a database that stored numbers in a base 256 format. Random. But nifty, no less.

Yep. I never said otherwise. I am merely stating the obvious that strtol() has some limitations as to what base you can use. It was for a bank with arbitary length numbers. Though like most banks, you aren't going to be getting numbers truly beyond 64-bit computation...

Random indeed as I cant even imagine a number in radix 256, since there are so many digits to think about.

I didn't design it. Such types of systems were invented waaaaaayyyyyyyy before my time when memory was an expensive luxury.

all right! thank everybody very much! actually i'm just a beginner for this! reading u guys discussion, i'm really get into it even i dont really understand it. Probably later, i will understand well what u guys are discussion. Anyway, very helpful, i appreciate that. I fixed the problem by what matsp said, use getchar() to read the newline. Pretty simple and easy to fix. ^_^

Which is surely a prefered way to do it since it eliminates the mixing of scanf() and fgets().
