C++ :: Getting Sum Of Two Randomly Generated Numbers

Feb 15, 2015

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;

C++ :: How To Get Rid Of Negative Number From Randomly Generated Numbers

Oct 21, 2013

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.

C++ :: How To Define New Color That Is Randomly Generated In Allegro

Feb 5, 2014

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

[Code]...

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.

C :: How To Store All Random Generated Numbers In Array

Feb 27, 2013

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)

Visual C++ :: Creating Loop To Call In Entries From Text File Named Set

Jul 14, 2013

I am trying to create a loop to call in the entries from the text file named Set. The entries of Set.txtare :

1 2 3
2 4 5
and so on .. (64 such combinations)[/CODE]

It basically means the first combination for testing is 1 2 3 and next has to be 2 4 5 and so i have 64 such entries defined in set

My test files are located in D://data// and are named tst_data1 to tst_data64.

I created a loop for test set but its incorrect

Code:
// loop for test samples
char basefilename[] = "D://data//";
char , testFilen[160], numiChar[10];

for (int i=1; i<=64; i++) {
strcpy(basefilenme, "D://data//");
strcat(testfilename, Set[]);

[Code] .....

How can i call the Set .txt and how to define it.

C++ :: Reading Numbers From A Text File

Sep 25, 2014

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() {
int amount=10;
int k[amount];

C++ :: Read The Numbers In A File While Ignore Text?

Sep 20, 2013

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?

C++ :: How To Calculate Certain Cells Of Numbers Instead Of Entire Text File

May 24, 2014

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>
