c - Setting a specific element of a char** array to NULL -


i attempting set last element in second char ** array null after encounter specific char in first array. 

int test(char ** args){    char ** chmd1;    for(int = 0; args[i] != null; ++i){      if(!strncmp(args[i], "<", 1)){         chmd1[i] = null;         break;      }      chmd1[i] = args[i];    }     for(int = 0; chmd1[i] != null; ++i){       printf("%s", chmd1[i]);    }     return 0; }

this code segfaults second loop goes on more iterations past null should be.

i want able able manipulating pointers , not using mallocs, i'm stuck.

this code segfaults second loop goes on more iterations past the null should be.

you have not allocated memory chmd1 , yet using points valid memory.

i want able able manipulating pointers , not using mallocs, i'm stuck.

you can't that. have use malloc (or 1 of other functions malloc group of functions: calloc, realloc) allocate memory chmd1 before can use it.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
