BANNER COMMAND CODE IN C
Here is where I put my days in class 11th in high school. Writing code for printing my name big in n no. of lines . Initially I did it in java, but then I was taught C in my college NIT,Allahabad, so here is the C code. Enjoy!
output for n=12 and string ="HELLO I AM MADDY" is :

program:this prints the input string consisting of multiple words in n no. of lines.
Its somewhat similar to the banner command in linux
Differences with banner command:
1.it can print string in n no. of lines where user implicitly decides value of n in code unlinke banner command
2.A particular char is printed with that char by default.This can easily be modified in code as A(i,n,'B') or A(i,n,'C')
3.it has support for printing more than 8 chars and printing in multiple lines when one gets filled
