Difference between 4 numbers

[funkyfela]

Hi,
am very new to c++, in school i was given a couple of assignments and i really dont know how to go about it.

question1
write a program that reads four numbers and find the largest and print the day of the week that corresponds to the number

question2
write a program which reads the average of two numbers and also print the remainder of the second number when divided by the first number

thank you very much!

One program at a time. One step at a time.

Question 1:

// Declare variables to store inputs
// Declare an array of strings representing each day
// Start for loop
// -- Ask user for variable input
// -- Start while loop, while input isn't valid
// -- -- Ask for input again
// -- End while loop
// End for loop
// Write simple algorithm to work out highest number
// Print out the string array at the index of that number - 1 

Make sure the user doesn't input something stupid. Presumably, the only numbers that should be entered are between 1 and 7, yes?

Don't forget, arrays start at index 0, if a user enters "1", array index 1 would actually be Tuesday, not Monday. Don't forget to subtract one from the entered number to get the correct day.

Question 2:

cin << num1;
cin << num2;
int sum = num1 + num2;
int remain = num2 % num1;

[MrHutch]

Couple of errors there, captacha. And it doesn't do what the question asks.

I would also refrain from posting code. Since it's classwork, best to give the OP the opportunity to try it themselves.

thanks for the replies.

thanks for replies. ihutch pls I need codes as I no nothing about c++ and I have deadline Friday. if I don't get it , I won't be allowed to partake in subsequent classes. pls
thanks

Hi iHutch105,

thanks for the help. i have done some for myself but i am lost

here is what i did so far, pls help improve.

thanks

#include <iostream>

int main()
{
// declaring variables to store inputs:

using namespace std;

int i, j, k, l;

cout << "Please enter a number...\n";
cin >> i;
cout << "And another...\n";
cin >> j;
cout << "And one more...\n";
cin >> k;
cout << "And one more...\n";
cin >> l;
cout << "Thank you!\n";

if (i > j)
{
if (i > l)
cout << i << endl;
}
if (j > k)
{
if (j > i)
cout << j << endl;
}

if (k > l)
{
if (k > j)
cout << k << endl;
}


if (l > i)
{
if (l > k)
cout << l << endl;
}


char response;
cin >> response;
return 0;
}

//declaring an array of strings representing each day

int DayOfWeek [] ={Sunday, Monday, Tuesday, Wednesday};

// starting a loop

Ok, so the inputs are fine but you haven't been clear on the specifics. Do you want the numbers input to be only between 1 and 7? How else are they going to correspond to days of the week if not?

One other thing concerning the inputs; why not make them an array? This would make your input loop so much simpler.

const int MAX_INPUTS;
int inputs[MAX_INPUTS];

for (int i=0; i < MAX_INPUTS; i++)
{
   cout << "Please enter a number: ";
   cin >> inputs[i];
}

As I said, you may want to include some validation that checks what numbers get entered.

Having that array will make finding the largest number super easy.

int largest=0;

for (int j=0; j< MAX_INPUTS; j++)
{
   // Check to see number at that array is larger than largest int
   // then assign accordingly
}

Also, your array of days:

string Days[7] = {"Sunday", /*etc*/};

Much happier to help out when you have a go yourself. Haven't given you complete answers there because it's best you learn yourself but hopefully that'll nudge you in the right direction.
