parkside's triangle..
create a program like this..
enter the size: 6
enter the seed: 1
output:
1
23
456
7891
23456
789123
sample2:
enter the size: 5
enter the seed: 3
output:
3
45
678

parkside should not exceed 10 while its seed should only be
not more than 9..
the number 138 is called well ordered number because the
three digits in the number (1,3,8) increase from left to right
(1<3<8). the number 365 is not well ordered coz 6 is larger
than 5.
write a program that wull find and display all possible
three digit well ordered numbers.
sample:
123,124,125,126,127,128,129,134
,135,136,137,138,139,145,146,147
148
149,156.......789
a number is perfect if it is equal to the sum of its proper
divisor..
6 is perfect number coz its proper divisors are 1,2 and
three.. and 1+2+3=6...
a number is deficient if the sum of its proper divisor is
less than the number..
sample: 8 is deficient, coz its proper divisors are 1,2 and
4, and 1+2+4=7.
abundant number, if the sum of its proper divisor is greater
than the number..
sample..12 is abundant coz 1+2+3+4+6=16 which is geater than 12.
now write a program that prompts the user for a number, then
determines whether the number is perfect,deficient and
abundant..
a number whose only prime factors are 2,3,5, and 7 is call
humble number,,write a program to find and display the nth
element in this sequence..
sample input : 2,3,4,11,12,13, and 100.. sample output : the
2nd humble number is 2,the 3rd humble number is 3,the 4th
humble number is ,the 11th humble number is 12, the 12th
humble number is 14, the 13th humble number is 15, the 100th
humble number is 450.
write the function int countchtr(char string[],int
ch);which returns the number of timesthe character ch
appears in the string. for example the call countchtr("she
lives in Newyork",'e') would return 3.
atoi, which takes a string and converts it to an integer.
write a program that reads lines(using getline), converts
each line to an integer using atoi and computes the average
of all the numbers read. also compute the standard deviation
Write a program which has the following seven functions.
The functions should be:
• main() this calls the other 6 functions
• fget_long() a function which returns a long data
type from a file
• fget_short() a function which returns a short
integer variable from a file
• fget_float() a function which returns a floating
point variable from a file
• fprt_long() a function which prints its single,
long argument into a file
• fprt_short() a function which prints its single,
short argument into a file
• fprt_float() a function which prints its single,
floating point argument into a file.
You should use fscanf() to get the values of the variables
from the input (the file) and fprintf() to print the values
to the other file. Pay attention to using the correct
format for each of the data types.

The purpose of this exercise is to benchmark file writing
and reading speed. This exercise is divided into two parts.
a). Write a file character by character such that the total
file size becomes approximately >10K. After writing close
the file handler, open a new stream and read the file
character by character. Record both times. Execute this
exercise at least 4 times
b). Create a buffer capable of storing 100 characters. Now
after generating the characters, first store them in the
buffer. Once the buffer is filled up, store all the
elements in the file. Repeat the process until the total
file size becomes approximately >10K.While reading read a
while line, store it in buffer and once buffer gets filled
up, display the whole buffer. Repeat the exercise at least
4 times with different size of buffer (50, 100, 150 …).
Records the times.
c). Do an analysis of the differences in times and submit
it in class.

Write the following function in C.
stripos — Find position of first occurrence of a case-
insensitive string
int stripos ( char* haystack, char* needle, int offset )
Returns the numeric position of the first occurrence of
needle in the
haystack string. Note that the needle may be a string of
one or more
characters. If needle is not found, stripos() will return -
1.
The function should not make use of any C library function
calls.
