Answer 1

#include <stdio.h>
#include <stdlib.h>

// int mblen(const char *string, size_t n);
// int mbtowc(whcar_t *pwc, const char *str, size_t n);
 
int main(void)
{
    int length;
    char str[6] = "x";
    wchar_t arr[6];
    
    length = mblen(str, MB_CUR_MAX);
    
    mbtowc(arr, str, length);
    arr[1] = L'\0';
    printf("wide character: %ls\n", arr);
  
    return 0;
