bit manipulation - c++ bit operations how to print out 16, 32 bits -

at moment have script prints out numeric values bits example

print((short) 1); 

i value of 00000001, how can value 00000001 00000000 , in case if print print((int) 1); value of 00000001 00000000 00000000 00000000. here code:

void printbyte(unsigned char x) {     (int = 0; < 8; i++)     {         if (x & 0x80) cout << 1;         else cout << 0;         x = x << 1;     }     cout << endl; }  template <typename t> void print (t a) {     unsigned char *p = (unsigned char *) &a;     printbyte(*p); }  int main() {     print((short) 1);      system("pause");     return 0; } 

you can use sizeof(t) within print determine how many bytes process , call printbyte each byte, e.g.

#include <iostream> #include <climits>  using namespace std;  void printbyte(unsigned char x) {     (int = 0; < char_bit; i++)     {         cout << ((x & 0x80) != 0);         x <<= 1;     } }  template <typename t> void print (t a) {         (size_t = 0; < sizeof(t); ++i)     {         unsigned char b = >> ((sizeof(t) - - 1) * char_bit);         //unsigned char b = >> (i * char_bit); // use little endian output         printbyte(b);         cout << " ";        }     cout << endl; }  int main() {     print((short) 1);     print((long long) 42);      return 0; }
