oh i forgot the input to the program is in the form of
either a U, D or B followed by an int
and at the end of this list, an enter

I solved it by myself thanks
after almost ripping my hairs out, i noticed that i miss typed something,

for(c=0;b<25;b++)
		{
//intead of
for(c=0;c<25;c++)
		{

thanks anyways
