Write a program that prompts the user for a value for i and displays the e value, and this is all i have so far. I was told it's suppose to have two for loops but i'm not sure where and how to do it and i know my output is wrong as well, also the use of a for loop is important. #include <iostream> using namespace std; int main (){ double count; double i=1; double e; cout<<"What is the value for i?"; cin>>i; for(count=1;count<=i;count++){ e!=1/count; cout<<"The value of e is equal to :"<<e<<endl; } system ("pause"); return 0; }

I have been developing a simple java game, however I would like to add some Music to my game because it seems quite boring whenever you play it.

Good day folks, I hope you can help me with this one, I want to create a game. Can you tell me where to start, what softwares I need to study and what particular knowledge I should have. I'm not new to programming so do you think it will be hard if I want to learn this kind of thing?

Hello, I am look for some help with a query where the query changes on the basis of input parameters. Like $variable = 'abc'; $rs=mysql_query("SELECT * FROM table WHERE `column`='$variable'"); But what about a scenario where this variable is not assigned or is null or blank. In that case I'd like the query to ignore that column altogether and look into other parameters. I have been looking into it for a while but haven't found anything useful. I am not even sure if its possible. Any help or inputs will be appreciated! Thanks

write a programme to capture 3 numbers and determine the smallest and the largest.

Hello! After I compile and run my program a windows error message shows up, it doesn't give some specific information it's just a standard windows xp error that asks me to send report. It gives me the error because in my code I have some basic math like this: int e = a - b; int r = c - d; int w = e / r; Even if I make a simple console program with only those lines , it still gives me the error. I'm using the latest version of DEV C++ on windows XP.

Hi, I was wondering is there a way where you can sell limited tickets. For example there are 55 seats in a bus and 55 people bought the tickets for the bus,the people who want to buy those tickets for the bus must wait for an hour. How would I implement this code in Dev c++ . Thank you.

hi, I am trying to make a variable equation solver using DEV-C++. I just need to know how to get C++ to solve an equation inputed by the user. So you input something like 1+1 and i need it to solve the problem and output the answer. heres an example: [CODE]#include<iostream> using namespace std; int main (char argc) { string n1; cin >> n1; // i input 1+1 int n2; solve n1 = n2; cout << n2 << endl; // it outputs 2 }[/CODE] thanks

Not sure if this is the right place for this, but here we go. Basically I would like to get back into building websites, but I have no idea which dev tools to use. I haven't built a website for about 5 years ago and then I was using Microsoft front page (mostly because it came with my computer). I'm not sure if this was any good but I got on with it fine. Basically, I would like some advice on where to start and what programs to buy (or better, download for free). I know some HTML and my …
