C :: Printing 21 Different Numbers That Are Randomly Generated?
Mar 2, 2014
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 <stdio.h>
#include <stdlib.h>
#include <time.h>
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;
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
[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.
//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];
[Code] .....
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] = {}; char wall = 178; int ViewDistance = 10;
I have a struct called Array and I'm to create a function to create a dynamic array that's fill with randomly generated integers from 0 to 50 (inclusive) and a function to destroy the array for freeing its memory. Below the code that I have written so far.
Code:
* Struct */ typedef struct {int *pArray; //the dynamic array int length; //the size of the dynamic array}Array; /* Function to create a dynamic array */ Array *initializeArray (int length) {int i; }
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)
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'm looking for something like this: A2 = [3 2 1 6 7 8 4 5]
How to randomly insert certain numbers into a linked list with 10 nodes. Meaning I want to put for example numbers 1 5 10 15 20 25 30 35 40 50 in random locations in the linked list.
how are we able to print out a random number (after using srand() and rand() ) - where you there is an unspecified amount of variables given. So, if the user selects yes to have another number given, how are we able to show the previous numbers and the current one?
I'm currently trying to write a program that takes an integer input from the user and displays that number of square-free numbers. I've gotten most of the program to work, but I encounter an error during the noSquare function that causes it to print incorrectly.
A square-free number is a number that is not evenly divisible by the square of any prime number. It's hard to see the bold in the code area, but it begins after the "//I think below is where the problem is"
#include <iostream> #include <vector> using namespace std;

I've gotten most of the program to work, but I encounter an error during the noSquare function that causes it to print incorrectly. I have bolded the area where I believe the problem is what I am doing wrong.
The problem with the program is that it prints ALL numbers from 1 to the input number instead of just the square-free.
A square-free number is a number that is not evenly divisible by the square of any prime number ....
#include <iostream> #include <vector> using namespace std; bool noSquare (int num); //Function to determine if the number is square-free vector<int> getPrimes(int num); //Function to get a vector of all primes below num bool isPrime (int number); //Function to determine if individual numbers are prime int main()

By the way, the in the middle of the code was me trying to bold a section, not an actual part of the code. I can't seem to find where to edit my original post.
//Finding prime numbers #include <iostream> using namespace std;
[Code]....
/*The program currently prints all the prime numbers up to n (For example, if 7 is entered, it prints out: 1, 2, 3, 5, 7. What I want it to do, is print out the first 7 numbers; 1, 2, 3, 5, 7, 11, 13.
