[Solved]-Trying Read Saved Game Connect4 Try Playing Press 0 Save Working Function Read Saved File Q37294900

i am trying to read from saved game Connect4. Try playing andthen press “0” to save; I am working on the function to read fromsaved file.

C computer language question

I have a text file that looks like this:

, , , , , , .
, , , , , , .
, , , ,R , , .
, , , , , , .
, , , , , , .
, ,R , ,Y, ,R.

I need to write a program that reads just the values(R or Y) andputs them in corresponding places in array[41]. So,array[6]=’R’,array[4]=’Y’.

I get weird output when I scan the array. the code i am usingand it doesn’t work.

#include <stdio.h>
