Could you help me with my c++ assignment plz?

[johnykf]

hello guyz im afraid if i understood this assignment unproperly:
could you give me the output of it plz? (how should the output of this assign be)

The monthly results for the best 3 employees of the month in a company are sent to the IT department for analysis and calculation in the following format:

1378 2496 3587

Those results are read as follows:
Example:
1378: 1 for the candidate number.
3 grade over 10 for Self-motivation.
7 grade over 10 for Professionalism.
8 grade over 10 for Teamwork.

The coefficients for the 3 attributes above are respectively:
Self-motivation: 5
Professionalism: 2
Teamwork: 3

Result for Employee 1 is: (3x5) + (7x2) + (8x3) = 53
Where the maximum result will be 90: (9x5) + (9x2) + (9x3)

Write a program to do the following:
1. Read and store the results for the 3 employees from the keyboard.

1. Calculate and print the result for each of the 3 employees.

THx!!

So what do you have so far? This site is not about giving it is about helping. If you put in the effort we will help you. help does not equal do.

Seems pretty clear assignment to me. What part don't you understand?

Since you have to work with each digit of the number it would probably be easier to get the number as a string instead of an integer. It can be done with an integer but it's a little more complicated.

hey bro can you check for me if this code is correct plz ? thank you

#include <iostream>
#include "stdafx.h"
using namespace std;

int main()

{
int result1,result2,result3, counter=0,x=0,y=0,z=0,z1,y1;

while(counter<1)
{
cout<<"Enter the first result: ";
cin>>result1;
while (result1>9999) {
cout<<"you need to enter four digits. Type again: ";
result1=0;
cin>>result1;
}
cout<<"Enter the second result: ";
cin>>result2;
while (result2>9999) {
cout<<"you need to enter four digits. Type again: ";
result2=0;
cin>>result2;
}
cout<<"Enter the third result: ";
cin>>result3;
while (result3>9999) {
cout<<"you need to enter four digits. Type again: ";
result3=0;
cin>>result3;
}
counter=counter+1;
}

cout<<"The results are the following:"<<endl;


x=(result1%1000%100%10);
y1=(result1%1000%100)-(x);
y=y1/10;

result1=(x*3)+(y*2)+(z*5);

hello ancient dragon. Thank you for your support. The part that i dont understand is the coefficient part "The coefficients for the 3 attributes above are respectively:
Self-motivation: 5
Professionalism: 2
Teamwork: 3"
Does it mean that if i put for example:
2453
3453
6323
the result 1 should be : 4x5 5x2 3x3 = 39
result 2: 4x5 5x2 3x3 = 39
result 3: 3x5 5x2 3x3 = 34

Thank you!

Does it mean that if i put for example

Yes, you got it correct :)

You may like to see this revision ...

1. that uses functions ...
2. that takes in ('crash safe') string input
3. that validates the input, in a loop, until valid
4. that demos using the same function in different ways, via a 'flag' variable ... also, 'default values'
5. that uses arrays ... so program can be made generic
6. that uses a 'data struct' ... and an array of struct
   ... and '[i]' and '.' notations
7. that uses Global constants so that the program can be easily revised to handle more than (array of size) 3
   etc...

See the added comments and note use of descriptive variable names ... to help 'self document' the code.

Enjoy ...
