Question

I have a short variable and i want to convert it to 2 bytes in iOS

short num = 10;
char *bytes;

Now I want to convert this num value into bytes

Please help me

Answer 1

May be like this
char * bytes = malloc(sizeof(char) * 2);

bytes[0]  =  (char)(num & 0xff);
bytes[1]  =  (char)((num >> 8) & 0xff);

EDIT : After all the comments below..

char * bytes  = malloc(sizeof(char) * 3);

bytes[0]  =  (char)(num & 0xff);
bytes[1]  =  (char)((num >> 8) & 0xff);
bytes[2]  = '\0' ; // null termination

printf("strlen %d", strlen(bytes));
printf("sizeof %d", sizeof(bytes));

Now you can understand the difference..
