int main()
{int n=1;
char *c=&n;
if(c)
printf("Little endian");
else
printf("Big endian ");
return 0;
}

#define BIG_ENDIAN 0
#define LITTLE_ENDIAN 1

int TestByteOrder(void)
{
short int word = 0x0001;
char *byte = (char *) &word;
return(byte[0] ? LITTLE_ENDIAN : BIG_ENDIAN);
}

something like this:

bool findEndianness() {
  unsigned int x = 0xAABBCCDD;
  char *px = (char *) &x;
  char px0 = *px;
  char px3 = *(px + 3);
  if (px0 == (char) 0xDD && px3 == (char) 0xAA) {
    cout << "you're big endian!" << endl;
  } else if (px0 == (char) 0xAA && px3 == (char) 0xDD) {
    cout << "you're little endian!" << endl;
  } else {
    cout << "you're mixed" << endl;
  }
}

{
short int word = 0x0001;
char *b = (char*) &word;
if(b[0])
  little endian
else
  big endian
}

does ppl literally mean jst code when there Question says wap..i mean u can always give a pseudo code n some explanation then code..coz code is not the important thing its the thought process...

+1 to sriks's comment. (I saw your comments elsewhere as well and I completely agree. I've made comments to this context also and gave up educating ppl about a year ago. Seems some guys just love copy-paste from other places.

Union
{
Int j;
Char c[4];
}x;

X.i = 1;
If(c[0] == 1)
Print little endian;
Else
Print big endian;

Instead of char c[4] it is better to make it generic as char c[szieof(int)];

union
{
int j;
char c[sizeof(int)];
}x;

x.j = 1;
If(x.c[0] == 1)
cout<<"little endian";
else
cout<<"big endian";

For this I think char c should be fine:

union
{
int j;
char c;
}x;

x.j = 1;
If(x.c == 1)
cout<<"little endian";
else
cout<<"big endian";

union TestEndian
{
int number;
char singlebyte;
}Test;

void tester()
{
Test t;
t.number=1;
if(t.singlebyte==1)
cout<<"Little Endian"<<endl;
else
cout<<"Big Endian"<<endl;

}
