My code compiles, but it doesn't get past this:
Here's the code:
#include <cstdlib>
#include <iostream>
#include <fstream>
using namespace std;
//ofstream random_numbers("randIntContainer.txt");
ofstream random_numbers("D:/StudentData/Documents/DataStructures/SortingAlgorithms/randIntContainer.txt");
void generateNumbers();

I can't get the sum of two randomly generated numbers - I don't believe the program is adding wrong what I think might be happening is upon hitting enter its adding two new randomly generated numbers -
Code:
// Program functions as a math tutor
#include <cstdlib>
#include <iostream>
#include <ctime>
using namespace std;
int main() {
// Constants
const int Min_Value = 1;

The program is supposed to be printing 21 different numbers that are randomly generated. Why am I getting the same number 21 times? Using dev C++ compiler.
Code:
/*prints random numbers between 1 - 99*/

#include <stdlib.h>
#include <time.h>

I have a error with one of my programs. I'm supposed to get rid of negative numbers when there are numbers that are randomly generated. Here is the middle part of the code.
{
int vectorLength = 10;
vector<int> bothSigns(vectorLength);
cout << " Input vector: ";
for (int i = 0; i < vectorLength; i = i + 1)
{ bothSigns[i] = rand()%201 - 100;
[code] .....
The part where i'm supposed to start is after the /////'s. However, whenever I input a number for the random numbers(not put in part of code), i keep getting a segmentation error.
How do i define a new color that is randomly generated in allegro.
I have this code here in the header file.
Code:
//FILE : circledefs.h
//PURP : Define some constants for circle & background
#ifndef CIRCLEDEFS_H
#define CIRCLEDEFS_H
#define NUMCIRCLES 3
//The frames per second for the timer
#define FPS 60

And what i want to do here is learn how to create a random number gen. Now a few questions if you don't mind telling me is.
1 - can I create 3 random generators in this header file? Or do I have to do this in main.
2 - If I do have to do this in main can I still create this defined RANDOM as a color.
3 - I am sooooo new to this all i know is cin and cout code for C++, so will i need to know more about pointers to do this.
4 - for fun how hard would it be to make a game in allegro that uses music to define how the enemy moves and attacks. (yes that would be the final project.
//This code gives randomly generated alphabets and if equal will cout the alphabet which is equal
1 #include <iostream>
2 #include <cstdlib>
3 #include <ctime>
4 using namespace std;
5 int main()
6 {
7 int a;
8 char array[10];

My question is how to check that randomly generated alphabets are equal e.g in 22 number line it should give output of equal alphabets if they are equal but it does not give equal alphabets what wrong in this code mention the wrong statement, how will i get right answer?
I've been trying to create a roguelike, and I was trying to create randomly generated rooms like in Rogue. I'm seperating my map array into sections and giving it a 50% chance of spawning a room, but right now it doesn't do anything but spawn solid rock. What am I doing wrong?
int MapSizeX = 100;
int MapSizeY = 100;
char map[100][100] = {};

So far I have managed to sort songs by their string length in main. The void function is there because i learned how to create it, but it's not being used because I dont know how to use it.
Expanding on main, how would I go about selecting a random song from the array?
#include <fstream>
#include <iomanip>
#include <iostream>
#include <string>
using namespace std;
struct Song {
string song;

Ok here I have a program that reads a word from a text file randomly and matches it with the definition. The user has to guess what the word is according to the definition.
I'm having trouble with my for loop, I'm not getting any errors. But I just know something is off.
Here's my code:
#include <iostream>
#include <fstream>

using namespace std;
int main(){
int number;
int count = 0;
int numOfGuess = 0;

So we're having an assignment for school where you code a Roulette game which simulates you playing and you can choose how many times you "play" to check how many times you'd win (if that makes any sense, im german :P)
Anyways, the problem is how do i store all the random generated numbers in an array while NOT doing this (it's just a snip):
Code:
void randomzahl(void){
int i;
int zahl5[5];
int zahl10[10];
int zahl100[100];
int zahl1000[1000];
int zahl10000[10000];
if(runden == 5)

Is it possible to loop randomly. For example
for ( int i = 0; i<= 6 ; i++ )
I don't want i to acsend from 0 to 6 but i want it to get all numbers randomly. For example
first time r = 5 second time r = 2 and so on
until it gets all the seven numbers
I want to create a randomly ordered array of integers where there are no duplicates. Is there a way of doing this in one iteration? Or maybe even a standard function for this?

I am trying to read numbers stored in a txt file to populate an integer array. The problem is that the numbers read from a file have to be treated as strings and then I am not able to put them in an integer array.
I tried the stoi function to convert the string in 'box' into an integer but I am getting an error.
Code:
#include <iostream>
#include <stdlib.h>
#include <fstream>
#include <string>
using namespace std;
int main() {

I want to write a c++ code, which will read in a file like this:
A: 10
B: 20
C: 30
while in the code, I would need the value of A B C, how can I let the cin ignore the labels like A:?
of course, I can write a file as
10
20
30
.
.
.
and use cin>>A>>B>>C; to read in those
but in this way, when the number of values increase, it is really hard to remember who is who?
As you can see, the code below calculates the average, sum, number of items, etc, for a list of numbers in two separate files and compares them with one another.
e.g. we will have a text file of 10 numbers;
45
65
24
26
26
36
35
100
109
433
etc...
The problem is that the code will perform calculations on all the numbers in the txt. or csv. file. This is problematic because if there is any text in the file, e.g. headings, then the calculations will not be performed. For instance, suppose that I only wanted to include rows 5-10 in the calculations, how would I specify this in my C++ code?
#include <iostream>
#include <cmath>
#include <math.h>
