"Strings" (char array + null terminator) - `char greeting[] = "hello, world!";` - `char greeting[x] = "hello, world!";` - STOP: What do you think `x` should be? :) - `printf("%s", greeting);` - Definitely want to show some of the stdlib string functions and some easy things that can make them fail - `strncopy` - `strlen`, etc - Overflows - `char greeting[256]` - Someone inputs a 300 character string... uh oh :) - memcpy into something that's not big enough - Examples: - Put `\0` character in the middle of a string array %% START CODE: [[string_examples.c]] %% ```c #include <stdio.h> #include <string.h> int main() { char nulled[] = "hello\0world"; printf("nulled: %s\n", nulled); printf("strlen(nulled): %d\n", strlen(nulled)); } ``` %% END CODE %%
