A "Read" operation occurs when a computer program reads information from a computer file/table (e.g. to be displayed on a screen). The "read" operation gets information out of a file (some computer languages use the term "get" instead of "read"). After a "read", the information from the file/table is available to the computer program but none of the information that was read from the file/table is changed in any way. A "Write" operation occurs when a computer program adds new information, or changes existing information in a computer file/table. An example of a computer program adding new information to a file would be when a company adds a new hire's details into its employee master file. An example of a computer program changing existing information would be when a company updates its employee master file if an existing employee changes their address. In this example, since the employee already existed in the employee file, the computer program would have had to perform a "read" at some point, to get the information out of the file/table (a fundamental rule of computer programming is that you can't update a record in a file/table unless you perform a "read" operation to get a hold of that record in the first place). Either way, the "Write" operation is what puts information in to a file. Some computer languages use the terms "put" or "update", but these are both "write" operations in general IT terms. Bottom line: Read = get information. Write = add or change information. HTH
Professional programmers would never write code from scratch if they could avoid it, but there may be legal reasons why an existing program cannot be modified. Amateur programmers and hobbyists. however, will often write programs from scratch purely to exercise their problem-solving abilities.
We can read and write to files with the help of file commands in c programming.There are so many commands related to file for read,write,append,delete etc.

Write mode over writes the existing file and if not present creates a new one. Append mode never over writes the existing file. Append mode opens the file and sets the file cursor to the end of the file so that any write operation can start from the very ending of that file. Hope I helped :)
To delete all the existing data in a file, simply open it in write mode. If you open the file in append mode, you need to overwrite the existing data to delete part or all of that data.
Write to the file, append to the file, and read or change its attributes.
2,220,000,000. A million requires you to append 6 zeros.
int top=-1; int stack[10];
If you mean merging two sorted list, that would be like this: to= empty WHILE NOT empty(a) OR NOT empty(b) DO IF empty(b) OR first(a)<first(b) THEN append(to, first(a)) a:= next(a) ELSE IF empty (a) OR first(a)>first(b) THEN append(to, first(b)) b:= next(b) ELSE IF first(a)=first(b) THEN append(to, first(a)) append(to, first(b)) # if you want duplicates in the output a:= next(a) b:= next(b) END IF END WHILE
read/write permissions/privileges allow the user to read, append and delete records from your database tables, however it cannot alter / create / drop the tables and its structures.Read/write privileges are ideal for forums and production websites that don't require creation or alteration of table structures on its normal operations.

When undertaking a write operation the read/write head usually has to use more power during a write operation as this operation must effect a change of state in the storage medium. On the read operation the read/write head merely has to detect this changed state.
