A small requesst to you to share your experience and questions as well.
System Coding Question:
Expectation is to write a class which uses below mentioned APIs to implement. I think this has many minor cases to take care of.
int write(void *dataPtr, size_t len);
int read(void *dataPtr, size_t len);
int seek(size_t location);// To execute C++, please define "int main()"
// Goal: Implement byte based IO over a block based interface.
// Consider a system that supports block based IO.
// Following APIs are provided by underneath block based Interface to you:
// int bSeek(size_t blockNum);
// int bWrite(void *blockPtr);
// int bRead(void *blockPtr);
// int bBlockSize();// Example input:
// seek(12) : seeks to x byte
// write(data1, 15)
// write(data2, 16)
// seek(17)
// read(data3, 2) : read 2 bytes from <seek> into data3Comments (5)
