Thread: any1 can solve this

Anyone with a rudimentary knowledge of C++ can solve that, yes. You need to work out how to solve it, and we will help you in that process, but we don't give you the answer, as this is not the "We do your homework for you" website, but rather one that offers help and answers to direct questions.

How far have you got so far? Can you input the numbers? Can you perform the loop to produce the basic numbers (1..5 in the first column in your code)?

Alright, so you've got a read statement, a conditional statement, a for loop, a few arithmetic calculations followed by a write statement. Not too bad...

Familiarize yourself with <iostream> and its cin and cout stream objects. Then read up on if statements and for loops. ... and if you don't know math, I'd read up on how exponents work. That's about all there is to it.

Here ya go buddy. I'm assuming this is not homework...

Code:

#include <iostream>

using namespace std;

void findSquareCube(int LowValue, int HighValue,int Increment)
{
     int memLowValue = LowValue;
    
     while(memLowValue <= HighValue)
     {
        LowValue = memLowValue;        
        cout << LowValue << "  ";
        
        LowValue *= LowValue;       
        cout << LowValue;
     
        LowValue *= memLowValue;     
        cout << "  " << LowValue << "\n";

        memLowValue += Increment;
     }
}
int main()
{
    int LowValue=0;
    int HighValue=0;
    int Increment=0;
      
    cout <<"\n\nEnter high value  ";
    cin >> HighValue;
    
    cout << "Enter low value  ";
    cin >> LowValue;
    while(LowValue > HighValue)
    {
        cout << "\nSorry, but low value must be less than or equal to high value.\n"
                "Please enter low value again  ";
        cin >> LowValue;                   
    }
   
    cout <<"\n\nEnter Increment value  ";
    cin >> Increment;
      
    findSquareCube(LowValue, HighValue, Increment);
   

    /*Don't be confused by these next 9 lines of code they are just to pause the program 
before termination - no big deal... */
     cout << "\n\n\nPress enter to EXIT program...";   
 
     int ch;
     if(cin.peek() < 0)
    {
        while ( (ch=cin.get()) != EOF && ch != '\n' );            
    }
    
    cin.get();

 return 0;    
}

Well this guy could easily just be a complete beginner, and not a student, who is looking for help. And I know that beginners just love examples, and no doubt need them, and even if he is a student, I am sure that answering just one simple question is not going to jeopardize his career as a computer programmer. Now if he keeps asking questions like this, then I can see the problem that you imply.

You are right. I am a novice, and I didn't realize. I will look for a better approach.

Whether ajoi24 is a beginner in his/her free time or a student in an academic institution, this is a homework question. Spoonfeeding without any attempt on ajoi24's part does more harm than good. This is why matsp asked questions like "How far have you got so far? Can you input the numbers? Can you perform the loop to produce the basic numbers (1..5 in the first column in your code)?" The idea is to guide ajoi24 to making an attempt, and only if this genuine attempt fails (or can be improved) then a "model answer" should be provided.

Can't argue with that logic... but having gone through some of the post here I was under the impression that the people on this board would never ever give a "model answer".





EDIT: This is actually an edit to post #4, it is no longer editable, and I didn't want to create another post. "if(cin.peek() < 0)" should be "if(cin.peek() > 0)".

And what does that tell you? Do you think that every single programmer on these boards is mean? In programming, more than anywhere else, it's important to be "learning by doing".

P.S. I also think that this is a homework question and if the OP's story is really true, then starting on a problem like that with "zero C++ experience" is just plain dumb.

Well, it partly depends on the actual question asked, and partly on the effort shown by the poster. I certainly have posted answers. But as you can probably understand, "learning to copy from the web" is not "learning to program". Providing a correct answer to someones homework simply provides the learning to copy from the web, not understanding of the process of how to program - which is something the original poster probably is trying to do [the fact that said person may have spent 3 days out of 4 days playing Quake/getting drunk/etc instead of working on the code, and is now in a desperate panic is not really an excuse for us - if it's a VALID excuse, bring it up with the tutor - if it's a lame excuse, then the poster may fail the class - which is probably better for most purposes than passing based on someone else's work].
