Marvelous Mazes

Your mission, if you decide to accept it, is to create a mazedrawing program. A maze will consist of the alphabeticcharacters
A-Z, * (asterisk), and spaces.

Input and Output

Your program will getthe information for the mazes from the input file. This filewill contain lines of characters which your program mustinterpret to draw a maze. Each row of the maze will be describedby a series of numbers and characters, where the numbers
before acharacter tell how many times that character will be used. Ifthere are multiple digits in a number before a character, thenthe number of times to repeat the character is the sum of thedigits before that character.

The lowercase letter "b" will beused in the input file to represent spaces in the maze. Thedescriptions for different rows in the maze will be separated byan exclamation point (!) or by an end of line.

Descriptions fordifferent mazes will be separated by a blank line in both input and output. The inputfile will be terminated by an end of file.

There is no limit tothe number of rows in a maze or the number of mazes in a file,though no row will contain more than 132 characters.

Happy mazing!

Sample Input

1T1b5T!1T2b1T1b2T!1T1b1T2b2T!1T3b1T1b1T!3T3b1T!1T3b1T1b1T!5T1*1T
 
11X21b1X
4X1b1X

Sample Output

T TTTTT
T  T TT
T T  TT
T   T T
TTT   T
T   T T
TTTTT*T
 
XX   X
XXXX X

这题提交以后一直说Compilation error.

Our compiler was not able to properly proccess your submitted code. This is the error returned:

code.c: In function 'main':
code.c:8:2: error: expected expression before '/' token
code.c:9:2: error: expected expression before '/' token

但是不管怎么检查都觉得没有错，后来把单行注释去掉后就AC了。。。。

原来ANSI C不允许用单行注释。。

AC代码：

#include <stdio.h>
#include <ctype.h>

int main(void)
{
	char ch;
	int i, count = 0;
	
	while ((ch = getchar()) != EOF) {
		if (isdigit(ch)) {
			count += ch - '0';
			continue;
		} else if (ch == '!' || ch == '\n')
			putchar('\n');
		else {
			if (ch == 'b')
				ch = ' ';
			for (i=0; i<count; ++i)
				putchar(ch);
			count = 0;
		}
	}
	return 0;
}
