About LinkBacksIs there a way to tell if your system is big endian or little endian with out running a program cuz I dont have gcc install? either sudo so i cant sudo install it.
This is a discussion on Big endian within the Linux Programming forums, part of the Platform Specific Boards category; Is there a way to tell if your system is big endian or little endian with out running a program ...

Well I can tell you that if you are using an Intel x86 based system, it is little endian. If you have a PowerPC, (old Apple machines) it is big endian (Apparently that architecture can do both).

Simple. Just analyze the first byte of a multi-byte value, eg:Originally Posted by kiros88
Code:int is_little_endian_machine( void ) { static unsigned long value = 1; static int result = *( unsigned char* )&value == 1; return result; }
Code:int main(void){srand(time(0));for(double l=rand(),l0=0,l00=0;;l0+=0.1){for(double l000=0;l000 <1;l000+=.001,l+=((double)rand()/RAND_MAX)/0x64,l00+=((sin(l*0x8*atan(l0)*l000-(l0*0x8*atan (l)))*0.5)+0.5)){l00-=floor(l00);for(size_t l0000=0,l00000=(size_t)(0x50*(l00));l0000<l00000;++l0000 )putchar(0x20);putchar(0x61+(int)((double)rand()/RAND_MAX*0x1a));putchar('\n');}}return 0;}
Yes, but is the OP not stating that he/she has no access to a compiler?

Doh! Yeah, I misread that (read: wasn't paying attention)...
Code:int main(void){srand(time(0));for(double l=rand(),l0=0,l00=0;;l0+=0.1){for(double l000=0;l000 <1;l000+=.001,l+=((double)rand()/RAND_MAX)/0x64,l00+=((sin(l*0x8*atan(l0)*l000-(l0*0x8*atan (l)))*0.5)+0.5)){l00-=floor(l00);for(size_t l0000=0,l00000=(size_t)(0x50*(l00));l0000<l00000;++l0000 )putchar(0x20);putchar(0x61+(int)((double)rand()/RAND_MAX*0x1a));putchar('\n');}}return 0;}
Google says: Bash Tips
Very good - thanks for finding that tabstop. I did not think of using the shell to check, but I will certainly remember this for future use.
