 Programing C++ CSC 284 Sec: D and E
1. Write a program following bellow points
i. Take a class Solver; private data will be integer
type -a, sum, i, j, x, r, count; 5 public functions will be-void solve1(), void
solve2(), void solve3(), void solve4(), void solve5().
ii. void solve1() will find out bellow pattern, 1 22 333
4444
iii. void solve2() will find out the floyd’s triangle, 1 2 3
4 5 6 7 8 9 10
iv. void solve3() will find out factorial with user input,
v. void solve4() will find out the average of 3 inputs,
vi. void solve6() will find out the summation of those
numbers who are not divisible by 5 between 100 to 250.
vii. Take a main function and create proper object to call
your required function.
