PROGRAMS ON DATA
FILE HANDLING
1. Write a program in a C++ to read the
content of a text file “DELHI.TXT” and display all those lines on screen, which
are either starting with ‘D’ or starting with ‘M’.
2. Write a program in a C++ to count the
number of lowercase alphabets and uppercase alphabets present in a text file
“BOOK.TXT”.
3. Assume a text file “coordinate.txt”
is already created. Using this file create a C++ program to count the number of
words having first character capital.
4. Write a program to count number of
lines from a text files that ends at ‘.’
5. Write a function in C++ to count the number of
alphabets, number of digita, number of white spaces present in a text file “BOOK.TXT”
6. Write a program in C++ to count the
number of vowels present in a text file “BOOK.TXT”.
7.
Assume
a text file “Test.txt” is already created. Using this file, write a program to create three files “LOWER.TXT” which
contains all the lowercase vowels and “UPPER.TXT” which contains all the
uppercase vowels and “DIGIT.TXT” which contains all digits.
8.
Write a program
in a C++ to display the sum of digits present in a text file “Fees.txt”.
9.
Write a program
in a C++ to display the product of digits present in a text file “Number.txt”.
10.
Write a program
in a C++ to find the largest digit present in a text file “Marks.txt”
11. Write a program CountYouMe() in C++ which
reads the contents of a text file story.txt and counts the words You and Me
(not case sensitive).
For example, if the file contains:
You are my best friend.
You and me make a good team.
The function should display the output as
