I have already get a hexadecimal machine code.How to convert hexadecimal machine code to "c" programming code? give me any software links to convert hexadecimal machine code to c program code.
The application you are requesting is referred to as discompiler. While disassemblers, coverts HEX file to Assembly Language, are quite common, discompilers are not commonly available.
