hi everyone , i write a program in C to determine the type of microprocessor ,so for this task i include in c code source a assembler code ,,,,
this my code
so in resulr i have one error in 17 line ,undefined symbole EAX ,,,so perhap i need to include another header file or what? thanks before for all helps
this my code
