Make a program that will ask the users to input 4 different numbers. After the user’s input the program will display the formula on the next line. Next line would be the presentation of the formula which the variables were substituted by the inputs from the user, then returns the average of the numbers entered. **All inputs are integers except average which is float with two decimal places.

I just don't understand how you would have it count how many negatives and positives there are based on the user's input? Here's the problem and the code it provides:
Modify the program so that is displays the average of the positive and negative numbers. (Hint: be careful not to count the number 0 as a negative number.)
Code:
#include <stdio.h>
#define MAXNUMS 5
int main() {
int i;
float number;
float postotal = 0.0f;
float negtotal = 0.0f;

The Program must allow users to enter any two positive numbers and then display the results.

This program was made to allow students to enter as many test scores as they want and the program will show them in ascending order and then will calculate the average of all test scores. It works wonderful until you enter a negative test score and then it throws the averaging process off. I can't seem to be able to make the program not accept the negative numbers.
I tried to work on this program for while, but I am not able to get it to work

When I run this code it asks me to enter a number. It doesn't matter what number I enter it gives me the numbers from 1 to 100 in one horizontal line.
I want this program to do something like this:
for example if the user enters n=6 the program should give:
0 1 2 3 4 5 6
7 8 9 10 11 12 13
and so on
I've reached a point in "Jumping into C++" where I need to make a program that converts input numbers into their word equivalent.
So far I've made it work for numbers 0-9999. I've tried implementing 10000-99999 but there are problems with the order of the words printed (57865 would print fifty thousand seven thousand eight hundred sixty five). But besides that, the program is absolutely enormous (for me) and I'm wondering if it can be shortened. Keep in mind I can only use loops and if statements so far. Here it is:
Code:
#include <iostream>
#include <string>
void extras(int e);
void digits(int x);
void tens(int xx);
void hundreds(int xxx);
void thousands(int xxxx);
//void tens_of_thousands(long xxxxx);

I have to write a program where the user will input integer numbers. How many numbers they enter is unknown, therefor you should use a repetition structure for the input. When the user is done, they will enter -1 to exit.
Create a dynamic array if the size=2( the initial size must be 2) Repeat until user enters -1.
I have to do this without using vectors.
This is what i have, I cannot figure out what to put in main. I was thinking of a do-while?

#include <iostream>

Write a program that allows a user to enter high scores of a game, keeping tracking of the name of the user and the score. Add the ability to show the highest score for each user, all scores for a particular user, all scores from all users, and the list of users.
This is the program I am trying to write, however I am having difficulty storing the users name and high score, I know I need to store an array for the score but getting confused because of the structure. (By the way I have to use structures as it is a problem from the structures chapter of the ebook I am doing). Below is my code so far. .

#include <iostream>
#include <string>
using namespace std;
struct highScore
{
string user;

int highestScore;
int allScores;

I develop a software using QT 5 open source IDE. Now my question is two-fold:
1. How can I create the final executable file that I can upload for my users? I understand that runtime DLLs shall be required and I have tried Enigma Virtual Box software for bundling runtime files. It does create the file that I can execute from any folder in my PC. However, surprisingly when I transfer that "boxed" file to another PC, it does not run. Both the PCs have Windows 7 installed on them.
2. Secondly, I see possible future issues with Antivirus Softwares. Apparently when I try to run the boxed exe file, it gets rejected by the Antivirus Software on my PC. Is there a way in which I can get my exe file verified/checked/registered by the Antivirus Softwares so that my users don't face any problems in executing the program.
I cannot afford the QT commercial licence, but I am prepared to buy any economical "setup file generating" software (if it exists).

I was supposed to sort out an input, getting rid of chars and only using the numbers. So 5a6g7we87hj9 would become 567879. I might be wrong in some way, but I used
if (scanf("%d", &n) {
printf(" %d", n);
}
else {
printf("Error);
}
and it sorted correctly.
I need to distinguish between number (float) and other non number characters. I was trying to use this:
Code:
#include <stdio.h>
#include <ctype.h>
float Ax;

scanf("%f

if (isdigit(Ax)) {....}
And whatever I type I receive "Segmentation fault". How can I detect that the float input is correct? Is there any built in function?
