Please explain then how to print fp fs ft?

Answer is 'D', Because comma operator used in the expression fclose (fp, fs, ft). The comma operator has left-right associativity. The left operator is always evaluated first, and the result of evaluation is discarded before the right operand is evaluated.

M getting segmentation fault even though m passing 1 parameter to it, can any 1 fix this problem?

We can use fcloseall(); then all the opened files will be closed.

The the correct option is C. "A.C"
there can be any no. of arguments passed to fclose.
But which file is closes depends on the functionality of the comma(,) operator. It takes the first argument.

@Bhanu prakash.
You telling that it takes the first argument. Simply you are making fool to c compilers because any compiler may be turbo c or gcc it read from the right to left. Any it leave the extra parameter.

While fclose() read only one argument. Then we pass to the 3 files that time it will close 1 one.

To close all the files opened with fopen()at a time, we can use file function closeall(). This function has no arguments.

fclose() can close only one file at a time. If more than 1 argument than it will take only first and ignore rest.
