Here's the program:
/* Program Start */
#include <stdio.h>
int main (void)
{
FILE *handler; // The "*handler" can be named as anything as you desired
char arrText[1000];
handler = fopen("Sampletext.txt", "r"); // We opened a file "Sampletext.txt" ready for reading
scanf ("%s", &arrText); // Scan the first line of the file
printf ("%s", &arrText); // Display the scanned data from file, to the console
fclose (handler);
return 0;
}
/* Program End */
If you wish to print the scanned line to text and not to console, use fprintf insted. fprintf can be executed in this form: fprintf (<file name>, "<format specifier> (or text)", <variable>);
Also, use "a" in fopen. This will append the current data to the text file.

Write java program to merge alternate lines from file1 and file2 into file1?
I suggest something like this:* Open file1 and file2 * Create a temporary output file, for writing * Read a line from file1, write it into the output file * Read a line from file2, write it into the output file * Repeat the previous two steps, while you are not at end-of-file in either of the two files * At this point, if you are NOT at end-of-file in file1, read the remaining lines of file1, and write them to the output (you can write a loop for this). * Similarly, if you are NOT at end-of-file in file2, read and write the remaining file. * Close file1, file2, and the output file. * Copy the temporary output file back to file1 * Erase the temporary output file

What is the difference between read and write in computer programming?
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
