How to read nth line of a text file in C programming using file handling?

C program to read the nth line of a file. 

This file handling C program illustrates how to read the nth content of a text file. 

Suppose your text filename is "documents.txt" and you want to read only 9th line of that file. Here's a source code to do so.

1. #include <stdio.h>
2. int main()
3. {
4. FILE* file = fopen("documents.txt", "r");
5. char line[256];
6. int i = 0;
7. while (fgets(line, sizeof(line), file)) {
8. i++;
9. if(i == 9 )
10. {
11. printf("%s", line);
12. }
13. }
14. fclose(file);
15. return 0;
16. }

Similarly if you want to read only the 1st/2nd/3rd/4th/5th or any other line then just run variable i till your desired line.  

For example if i  want to read the 10th line of the same file

if(i == 10 )
1. {
2. printf("%s", line);
3. }
