why use of %n in printf() is not printing the number of variable occurrence before %n In C?

With these it helps , Per C 2018 7.21.6.1 8, for the conversion specifier n:

Printing a number without using *printf

Any of those help If your libc contains an itoa() function, you can use it to convert an integer to a string.
Otherwise you'll have to write the code to convert a number to a string yourself.
code :
/* itoa: convert n to characters in s */
void itoa(int n, char s[])
{
   int i, sign;

   if ((sign = n) < 0)  /* record sign */
      n = -n;           /* make n positive */
   i = 0;
   do {  /* generate digits in reverse order */
      s[i++] = n % 10 + '0';  /* get next digit */
   } while ((n /= 10) > 0);   /* delete it */
   if (sign < 0)
      s[i++] = '-';
   s[i] = '\0';
   reverse(s);
}

printf isn't printing the right number

I hope this helps you . int *fileItems[]; is equal to int ** fileItems; Most likely you want a array of integers, and not array of pointers to integers.
Change struct declaration to int * fileItems;, and allocate list once before loop:
code :
myFile.fileItems = malloc(sizeof(int) * initialNumberOfElements);
myFile.fileItems = realloc(myFile.fileItems, sizeof(int) * biggerElementCount);

printf printing garbage number

seems to work fine The code as shown prints the address of msg since you do push offset msg. printf expects the value to print, not a pointer to it. As such, this should work:
code :
     mov eax, 17h       ; 23
     mov ecx, 1Eh     ; 30
     add eax, ecx
     push eax
     push offset fmt
     call printf 

Difference in outputs while printing value stored in a variable and printing value directly using printf()

wish help you to fix your issue Please be aware that 0.001 is a double value.
In the first example you assigned the double result to float, truncating its significance, which was then promoted to double when passed to printf.

wish help you to fix your issue I'm trying just to print a simple thing that says : Hola hi hello, but for some reason it is printing what I want but I get some numbers on my output , You have to use ho.name:
code :
System.out.printf("%s hi hello", ho.name);
