Initialize char array to hold non-null-terminated string


This question already has an answer here:



A string literal is a C-string which, by definition, is NULL-terminated.

Either ignore the final character, revisit your requirements (why do you care about a final character?!) or … I dunno, something else. Perhaps generate the objects with xxd?

I would do:

size_t length = 45;
char s[] = "The actual string is much longer then this..";
s[length - 1] = ".";

See what you have there has a trade-off between readability and functionality and I think that you can get away easily with this, since you can not avoid the NULL terminating string in the "normal" initialization.

If I were in your shoes, I would re-consider my approach and use std::string.

The terminating nul will be omitted if it doesn't fit. Since your strings are all fixed length, that's not a problem to arrange. For example:

#include <stdio.h>

char foo[3][4] = { "four", ".by." , "3333" };

int main(void)
    for (int i = 0; i < 3; ++i)
         for (int j = 0; j < 4; ++j)

No. If you want essy to write code, copy to a second array but miss off the last char. You can use a char pointer in the first case to perhaps save some memory

There is no way to have a string literal not null terminated.

But you actually want to pack a number of strings densely and you know both the sizes and the strings at development time.





to pack them you can safely do:

char const s[] = "First""Second""Third";

You only need to save lengths and properly reconstruct termination in case you want to print or use std string. That is easy though.

As a bonus you have saved from the excess pointer you would have to store for each and everyone string needed.

Should you include or ignore

git gradle android-gradle-plugin

When working on a team of android developers using gradle as your build system. Should you include gradle/wrapper/ in git, or should it be part of your .gitignore?
