C C String This article will introduce multiple methods about how to truncate string in C. Use Custom Function with Pointer Arithmetic to Truncate String Since the strings in C are just the character arrays terminated with null byte - \0, we can implement a custom function that moves the ...

The simplest rule is also the one that creates the most work for the developer and the library designer: never write to a string buffer without knowing how much space you have to write into. The design of strcpy makes the most basic mistake here. There is no way for strcpy to safely wr...
