For little endian lower-order byte of the number is stored in memory at the lowest address and for big endian higher-order byte is stored at lowest address.

#include
#define BIG_ENDIAN 0
#define LITTLE_ENDIAN 1

int main()
{
int value;
value = endian();
if (value == 1)
printf(“Little endian\n”);
else
printf(“big endian\n”);
return 0;
}

int endian() {
short int word = 0×0001;
char *byte = (char *) &word;
return (byte[0] ? LITTLE_ENDIAN : BIG_ENDIAN);
}

Thaks to every one but
i want the c program that show the system architecture is little or big endian

ARM processors could work in both modes either little and big endian.
In the ARM9TDMI, the “BIGEND” can be set (0 or 1) for instruction and data fetches…but only affect 16bit or 8bit fetches, while leaving the 32-bit word access unaffected.

It’s entirely dependent on the Processor architecture.
Commonly used Examples : -
Big Endian : Motorola 6800, IBM Power
Little Endian :x86, x86-64, 8051 etc
Well just to share more. There’s another category that is : Bi-Endian which can behave as either of the two categories mentioned above. Most Important example is ARM, Power PC or MIPS.
