This output is not used as text file.It is entered in the command window of the matlab those functions(count,findstr()) works using only in the file.
Sample output:
Enter a text:
I am a man
I love my mother
I love movie$
No.of lines=3
Kindly help me using character array or cell array no more predefined functions should be used

Read about strfind. YOu can search for you string using this.

Read about count() and extractBefore() and newline() .
Just remember that if you find one newline then that means you have two lines.

count and extractBefore and strfind all work on string() objects or character vectors that are already in memory. They do not do file I/O themselves; for reading the file, see either fileread() or fopen() together with fgets() or fgetl()
