Gettext/Django for german translations: formal/informal salutations -

i maintain pluggable django app contains translations. strings in python , html code written in english. when translating strings german, i'm fighting problem german differentiates between formal , informal speech (see t–v distinction ). because app used on different sites, ranging social network banking website, can't support either formal or informal version. , since translations can differ quite bit, there's no way can parameterize it. e.g. sentence "do want log out?" have these 2 translations: wollen sie sich abmelden? (formal) willst du dich abmelden? (informal) is there in gettext me this? you can use contextual markers give translations additional context. logout = pgettext('casual', 'do want log out?') ... logout = pgettext('formal', 'do want log out?')

c - void* type to char* type leadng -

-
the man has code #include <conio.h> #include <stdio.h> void dbleint(void *a) { *((int*) a) *= 2; } void deleteevenint(void* a) { int tmp = *((int*) a); if (tmp % 2 == 0) { *((int*) a) = 0; } } void dbledouble(void *a) { *((double*) a) *= 2.0; } void deleteevendouble(void* a) { int tmp = *((double*) a); if (tmp % 2 == 0) { *((double*) a) = 0; } } // function takes array, size, size of 1 element , function //pointer, // applied elements of array void map(void *arr, unsigned num, size_t size, void (*fun)(void *)) { unsigned i; char *ptr = (char*) arr; (i = 0; < num; i++) { fun((void*) (ptr + i*size)); } } why leads void* type char* type? can see thats error, when change code , dont lead it, why? you're not allowed perform arithmetic on void pointers in c. following code illegal: void *foo = whatever; foo + 1; by casting foo char * , can perform arithmetic on pointer.
