I have a char array buffer that I am using to store characters that the user will input one by one. My code below works but has a few glitches that I can't figure out:
Can somebody please explain to me what is going on and perhaps how I could fix this? Thanks.
char Buffer[8]; //holds the byte stream
int i=0;
if (/* user input event has occurred */)
{
Buffer[i] = charInput;
i++;
// Display a response to input
printf("Buffer is %s!\n", Buffer);
}
Output:
tagBuffer is 1┬┬w! tagBuffer is 12┬w! tagBuffer is 123w! tagBuffer is 1234! tagBuffer is 12345! tagBuffer is 123456=! tagBuffer is 1234567! tagBuffer is 12345678!
tagBuffer is 123456789!
You have to end the string with a \0
character. That's why they are called zero terminated strings.
It is also wise to allocate 1 extra char to hold the \0
.
