I am wondering is there a way to make function A uses random number stream say starting from srand(1) and function B uses random number stream say starting from srand(2) in the same program.
View 3 RepliesI'm working with inheritance and pure virtual functions, and I want to overload an output stream operator. However, every time I run the program I get this: 0x7fff00ee98c0.
I'll include a base class and a derived class so you can see what I'm talking about.
Base:
#include <iostream>
using namespace std;
#ifndef _Insurance_h_
#define _Insurance_h_
[Code]....
The application is something like this (I'm assuming the user has already inputted the name, salesperson, make, model, etc):
#include "Auto.h"
#include <iostream>
using namespace std;
#include <vector>
vector<Insurance *> sales;

I am trying to write a function that extracts chunks of numbers from a stream (ie if i had "ui33ui24ui23hjdwejf" it would extract the chunk 33), and its finished, but it wont compile. errors here: [URL] ...... its only one line in an include file, but im stumped. anyways, this is the most updated version of the code: [URL] .....
View 1 Replies View RelatedI wrote a program to write text contents to file stream through fputs, the file stream address was changed in the middle of writing text content to the stream (11% text content have been put into the file stream), that cause the file stream pointer can be evaluated problem and raise exception on stream validation code in fputs library function, my question is what things could go wrong to make file stream pointer changed its address to something else or a NULL pointer if the file stream have not been flushed and closed.

I am working with C++ in Visual Studio. It's my first semester doing anything like this ever. Still, I am embarrassed that I am having trouble with this simple "coin flipping" program. The user tells the program how many times to "flip the coin" & then the program tells the user the results of each flip. You'll see I am randomly generating a 1 or a 2 within the function coinFlip to represent heads or tails. However, the problem is that if the user wants more than one coin flip, the "random" number stays the same for all of them, resulting in all heads or all tails. I am thinking this is an issue with the for loop that I have within the function coinFlip.

#include <iostream>
#include <iomanip>

When I run this program it always generates the number 41 or 42. Why is this? Even if I add the code
magic = rand()%100 + 1;
to specify a range of 1 to 100 it's still always 41 or 42.
This is exactly the same code my book uses just without the cout << magic statement

I'm making the n puzzle game (15 puzzle), but having a problem generating random numbers without the duplicates.

I've been having 3 days worth of difficulties with a part of my code for a moving-a-robot-around-blocks problem.
No error messages; it runs, it just, sadly, isn't doing what I want it to do.
When I isolate the random-number generating part of the code, it works just fine and give me numbers 0-7. However, when I put those random numbers into another functions to use them as x and y coordinates in the matrix (in order to randomly position 10 blocks, represented by the number 10), and then go to print the matrix (which should be all zeros except for 10 100s), I get a large random number in each position.
#include <stdio.h>
#include <time.h>
int getXCoordinates() //this function gets random x-coordinates in matrix {
int x;
x=rand()%8; // random number 0-7

I made a function that provides random number to a matrix. The function works fine but with one problem, every time i call the function it provides the same numbers to every matrix.
void randomMatNumbers(int **p, int rows, int cols) {
int i, j;
srand(time(NULL));
for(i = 0; i < rows; i++) {
for(j = 0; j < cols; j++)
p[i][j] = (rand() % 199) - 99;
}
}
I have a code for random numbers between 0 and 90 but i can't figure out how to change the output for numbers to asterisks. Ex. if the random number is 8 i need it to print 8 asterisks.

So in C#, I'm trying to create a random number between 0 and 70billion. However, Random() doesn't work because the value is Long. I've looked at a bunch of solutions online, but it seemed like they weren't allowing values on the low range. I also saw some bit-shifting stuff, but not sure if thats the best way and I don't quite understand how to do it.

The problem is that It generates a random number that can be the same as the last time. So I figured out, that I need to save my random number so I can use it later, as a if statement.
If saved number == r then it generates a new number.
how to save my generated number on OnNavigatedFrom method.
I am making a random number generator. I have fixed all issues except for one. I am supposed to ask the user for how many digits the user wants the numbers to have. How many numbers does the user want. Then randomly generate numbers according to what the user entered. So if the user said 2 digits and wanted 4 numbers then it would output 4 random numbers in the range of 10 to 99.
My notes from class show this working correctly. And it does work correctly. But I don't understand the math here or how the modulus effects it. I was able to get 1 and 2 digits to work but once I get to 5 it doesn't generate numbers correctly. it will only generate number s
Code: int min =1;
int max = 9;int number1 = rand();
cout << number1 % max + min << " "; h
Here is the 3 digit code I have. I also need to figure out how to make it unique so no number generates more then once. I think the issue may be that the numbers are not unique and it is generating the same number and that is somehow effecting the numbers it is outputting. It is either that or my math is wrong.
Code:
if (intLength == 5) {
for (int i = 0; i<intQuantity; i++) {

Write a program that generates an array of 20 random numbers between 1 and 100. Use a loop to output the numbers on the screen with a field width of 4 characters. Write code that will reverse the numbers in the array and then output the numbers to the screen with a copy of the same output loop used with the original numbers.
