The scope of msg1 to msg4 is limited to msginput(char*). Once the
function returns, the storage (on the stack) is destroyed, and with it
your data. It looks like you are trying to store prior messages in those
arrays, but everytime you return to the function, everything will be
garbage but char* msg.

Either make msg1 - 4 global, or put them someplace where they will
persist throughout their use.
