Q41.

Choose a correct statement about File Write Mode "w".

File *fp;
fp=fopen("abc.txt","w");

If the file abc.txt is not found File abc.txt is created on disk.

If the file abc.txt is found, fopen() returns a FILE pointer as usual. Every time, contents of abt.txt are overwritten in "w" mode.

Read operation is not allowed in "w" mode.

All of the above

Discuss

Answer: (d).All of the above

Q42.

Choose a correct statement about C File Mode "w+".

FILE *p;
p=fopen("abc.txt","r+");

r+ mode allows reading of existing contents of file abc.txt only if file is found.

If file is not found, NULL is returned by fopen().

You can read existing contents, edit existing content and add new content.

All of the above

Discuss

Answer: (d).All of the above

Q43.

Choose a correct statement about C file mode "w+".

FILE *fp;
fp=fopen("abc.txt","w+");

Like "w" mode, "w+" mode creates a new file abc.txt if not found. NULL is only returned if some other problems in PC exist in opening a file.

w+ mode allows you to read the file also. Only after writing, you can read contents if any written. Before writing existing contents are emptied.

w+ mode always makes a file contents empty like w mode.

All of the above

Discuss

Answer: (d).All of the above

Q44.

Choose a correct statement about C file mode "a".

FILE *fp;
fp=fopen("abc.txt","a");

"a" is for append operation. You can append or add new content to the existing contents.

If file is not found, new file is created.

You can not write read file contents.

All of the above

Discuss

Answer: (d).All of the above

Q45.

Choose a correct statement about C file mode "a+".

FILE *fp;
fp=fopen("abc.txt","a+);

a+ mode always appends new data to the end of existing content

a+ mode creates a new file if not found or existing.

a+ mode allows reading also. mode "a" allows only appending not reading.

All of the above

Discuss

Answer: (d).All of the above

Q46.

Choose a correct statement about opening a file in binary mode for reading.

FILE *fp;
fp=fopen("abc.txt","rb");

rb mode opens the file in binary mode

Binary mode is just reading or writing in bytes instead of integers, characters or strings.

Binary mode saves memory occupied by contents.

All of the above

Discuss

Answer: (d).All of the above

Q47.

What is the syntax for writing a file in C using binary mode?

FILE *fp;

fp=fopen("abc.txt","wr");

fp=fopen("abc.txt","wb");

fp=fopen("abc.txt","wbin");

fp=fopen("abc.txt","b");

Discuss

Answer: (b).fp=fopen("abc.txt","wb");

Q48.
