Program to find endianness.

Solution #1: Finding endianness of a machine is to detect whether the machine is little endian or big endian. In a little endian machine the least significant byte is stored first whereas in a big endian machine the most significant byte is stored first. Here is the code,

#include 
#include 

int main()
{
    int i = 1;
    char* ptr = (char*)&i;

    if(*ptr)
        printf("Little Endian\n");
    else
        printf("Big Endian\n");
    return 0;
}
