C++ Help

[Jburks8]

Any shot anyone could lend me any C ++ help for school? I'm not very computer savy. The projects are probably a piece of cake for anyone with even a little bit of C++ knowledge.

Here they are:

1). READ THE PROBLEM: Write a program to find the smallest number, the largest number, and the average of any five numbers entered by the user. For example, if the five numbers entered are 1, 2, 3, 4, and 5, the answers should be smallest =1, largest=5, and average=3. (Your program should handle any five numbers from 1 to 1,000, in any sequence entered.)


2). READ THE PROBLEM: Write a program to ask for any amount from 0 to 99. This is the amount of change to be made. The program should calculate the number of quarters, dimes, nickels, and pennies to make the specified change with the fewest coins possible. For example, if the amount is 92 then your program should have output similar to this: Q=3, D=1, N=1. P=2.


Thanks in advance for anyone who may be able to help or offer me any advice!

Those are actually simple, but I am too lazy to help you. When I am too lazy to do something, I post it on www.stackoverflow.com. The nerds there have done like 90% of my programming since they existed.

Just don't say it's HW, make up something.


---

For the first one I'd like store the five numbers in an array, then run them through min() and max() and through a for loop to do the average.


---


For the second one define the value of coins, then take the input int and just go through them.

#define QUARTER 25

// then in main():

int numquarters = 0, numdimes = 0;

int i;
cin >> i;

while ( i != 0)
{
      if (i >= QUARTER)
      {
          i -= QUARTER;
          numquarters++;
          continue;
      }
     // dimes etc fall thru
}

printf("Q=%d, D=%d, ...", numquarters, numdimes, ...);

sry lazy

Awesome man, I'll try and post something there for sure. The help that I got from my instructor was this:

#include <iostream.h>

void main()

{int amount, Q, D, N, P;



Q=0; D=0; N=0; P=0;



cout << "Enter amount" << endl;

cin >> amount;

cout<<endl;


if (amount>24) {Q=Q+1; amount=amount-25;}

if (amount>24) {Q=Q+1; amount=amount-25;}

if (amount>24) {Q=Q+1; amount=amount-25;}

if (amount>9) {D=D+1; amount=amount-10[You must be logged in to view images. Log in or Register.]

your instructor makes me want to strangle young children, thats the most noobish code I've ever seen out of someone with a degree in the subject

<iostream> not <iostream.h>, c'mon lets use standards
void main()
he declares QDNP, but then assigns them base value on a different line(s)
no use of overloaded operators like ++ or -=
what a lazy fuckng way to account if there is more than 2 quarters, whats he want 9 if statements for pennies? copypasta that totally violates D.R.Y.
srsly wtf



god this rages me

What makes you think he has a degree in this? [You must be logged in to view images. Log in or Register.] All the programming instructers I've had at my college were all adjuncts with no relavent degree.
Plus, when teaching its easier to read this way for programming newbs. Besides, things get easier when they learn about for and while loops. I'm under the assumption that he hasn't introduced them yet because he gave them this:

if (amount>24) {Q=Q+1; amount=amount-25;}

if (amount>24) {Q=Q+1; amount=amount-25;}

if (amount>24) {Q=Q+1; amount=amount-25;}

if (amount>9) {D=D+1; amount=amount-10

[Ihealyou]

Q = amount / 25
amount %= 25
D = amount / 10
amount %= 10
N = amount / 5
P = amount % 5

No loops, and its not retarded.

amount &= 25
amount &= 10

You mean %= ?

&= is bitwise assignment.

Lol, I didn't even realize I wrote &= until you said that. In my defense, it was on my phone and % and & are both tall and squiggly, so they're basically the same thing anyways.

Under normal circumstances I'd agree.. but it's typos just like that that make you spend a fucking hour trying to figure out why your program isn't working correctly, debugging the shit out of it... and then it hits you in the face like a brick and you proceed to facepalm for 5 minutes.

Too many times that happens to me. Infact I spent over an hour just last night trying to figure out why some code was acting wonky and its because I did a delete on a char pointer instead of delete[], in a completely different function.

Ya, don't forget that loops come later. We did the same thing in the programming classes I had to take for chemical engineering.
