#include struct Single {     int num; };   void printSingle(int f) {     int binaryNum[33];     int i = 0;     while(f>0)     {         binaryNum[i] = f % 2;         f = f/2;         i++;     }     for (int j=i-1; j>= 0; j--)     {         printf("%d",binaryNum[j]);     } }   int main() {     struct Single single;     single.num = 33;     printf("Number: %d\n",single.num);     printSingle(single.num);     return 0; }

The code I have given is the code that was required for these sections Which I have finished     I just need help with the highlighted bullet points sections so what I really need help with is understanding why I had to do the code in this way  #include <stdio.h> struct Single {     int num; };   void printSingle(int f) {     int binaryNum[33];     int i = 0;     while(f>0)     {         binaryNum[i] = f % 2;         f = f/2;         i++;     }     for (int j=i-1; j>= 0; j--)     {         printf("%d",binaryNum[j]);     } }   int main() {     struct Single single;     single.num = 33;     printf("Number: %d\n",single.num);     printSingle(single.num);     return 0; }

please anser the practice assgnment questions in th images attached. please leave your answer in C++ code ONLY

Code with comments and output screenshot is must. Thank you!
