hi all
say if i were to use getchar(); and i was to the character as many times as it's entered (since it's goign to be a in a loop) yet for the last repetition, it is a different character, for example;
if i entered rrrr and i wanted the last character to be changed to t. the end character is defined to be preceeding a end of character ascii digit (10).
it would produce rrrt
thanks in advance.
