Here is a sample code to view the memory of an int type.
1 #include
2 int main (void)
3 {
4 int x = -3;
5 unsigned char const *p = (unsigned char const *) & x;
6 size_t i;
7 for (i=0; i < sizeof x; i++)
8 {
9 printf("%02X ", p[i]);
10 }
11 printf ("\n");
12 return 0;
13 }
14
The output is: FD FF FF FF (my machine is 32bits x86)
As the output is little endian, so the number should be FF FF FF FD
binary format is:11111111 11111111 11111111 11111101
complemental code: 10000000 00000000 00000000 00000011(=-3)
So the consequence is the int type stores in computer as complemental code.
