int main()
    FILE *fp[2];
    if((fp[0]=fp[1]=fopen("test.txt","w"))!=NULL)  //test.txt file should be empty during first compiling
    return 0;

what will be printed in file “test.txt”. and also am not understanding what is done after “fputs("one",fp[0]);” and “fputs("two",fp[1]);”

can anyone tell me with explanation...please….

one will be printed.

Reason:- fp[0] and fp[1] are having same reference i.e pointing to the same buffer for writing

Now when fp[0] writes one and close the buffer thereafter fp[1] write two but it does not go into the file as it is closed by fp[0]

if i write fopen("test.txt","w")) after fclose(fp[0]) the will effect???????????

It will overwrite previous written one with two because 'w' will clear all the data present in file and then write
okay thankyou....!
