Essentially I'm required to write a program which scans a tic-tac-toe board with the following input.
2 1 0
1 1 0
2 0 2
and gives the following output:
. X 0
X X 0
. 0 .
Where I'm stuck is how do I receive multiple lines of input with scanf? Any words of advice would be appreciated.
If you are only using scanf to read integers, then you don't need to worry about multiple lines. The scanf documentation states that all format specifiers except %c and %[ skip leading white space, which includes spaces, tabs and newlines. So if you just keep reading with scanf("%d", ...) you will get the desired behavior.
However, if for some strange reason you need to read line-by-line, you can read a line with fgets and then use sscanf to scan the line you just read.
