for(int i = 0 ; i < SIZE ; i ++)
{
scanf("%d" , & selection[i]);
srand((unsigned) time(&t));
draw[i] = rand() % 50; //feeling could be a problem with this line of code :::::
}
is it possible to do this. i am trying to get 6 different numbers stored into 6 elements of an array . this is the piece of the code i think there is a problem with. ie my program scans the numbers and then crashes at this point so think it could be something to do with the commented line?
So first I have to display a 2D array with all 0s, which is pretty easy.
#include <iostream> using namespace std; int main (){ int array[5][5]; for(int a=0; a<5; a++){ for(int b=0; b<5; b++){ array[a][b] = 0;
[Code] ....
So this displays
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
Next, this is where it gets confusing. I have to create a virtual creature by storing a letter into a random position in the array (the array can be up to 20x20 in size). Then make a function that searches the array for creatures, so it would search for that character. When it finds a creature, it should randomly decide to either move the creature to an adjacent position, or have it stay where it is. After, it should ask the user to create a new creature, or quit.
So how would I go about adding & modifying the current code to achieve what is listed above?
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.
The program has two array of character. One of them has size 26 and is initialized with the alphabet a to z. A random number generator generates two numbers and these two numbers are used to index into this array of alphabets. The second array is used to hold the indexed alphabets. For example, the first row is the value held in the second array and the second row are the two generated numbers.
b g c z k e <- letter index by generate number n1=1 n2=6 n1=2 n2=25 n1=10 … … … … n2=4 <- generated n1 & n2
Please see illustration below for clarification on the above question.
Element a b c ……… x y z Index 0 1 2 ……… 23 24 25
Array2 Element a b c ……… x y z Index 0 1 2 ……… 23 24 25
Final state after program execution
Array1 Element a b c ……… x y z Index 0 1 2 ……… 23 24 25
Array2* Element c e m ……… z f g Index 0 1 2 ……… 23 24 25 Random No generated 2 4 12 ……… 25 5 6
* Actual char element allocated to each index location will depend on corresponding random number generated. Program completes execution after filling all 26 locations in Array2.
I'm currently working on a code, its a wheel of fortune type of game. I have specific values of an array of size 10, and i have to get these at a random. so they would not print out in order. but how to assign each value of the random to the array.
#include <stdlib.h> #include <stdlib.h> #define CHANCES 5 int main(void){ int num, i; int money[10] = { 100, 300, 200, 350, 250, 150, 175, 500, 50, 75 };
I need to create A program That makes a 12x10 Array Grid Filled With Random Numbers From 0-99.
Then I need To Allow The User To Input A Number Between 0-99 And Then The program will then search through the array and count how many of the users number there is inside the array.
Code:
#include <iostream> using namespace std; int main() { int input; int number; int row=0; int col=0; int Array [12][10];
I wanted to find all the prime until a specified limit in C. I use the Sieve of Eratosthenes. But when I define the limit to anything more than a 7 digit number the program terminates.
Code:
#include<stdio.h> #define limit 1000000000 int main(void) { unsigned long long int i,j; int primes[limit] = {0}; //int count =0; for(i=2;i<limit;i++) }
[code]....
I believe that this might be because the size cannot be declared array cannot be more than the a 7 digit number. I think so. how to store a 10 digit number in C?And can't unsigned long long hold a 10 digit?
I'm running a game online and designing a program to generate Enemy Stats. Basically, it's supposed to generate 25 numbers between 0 and 7(to represent 8 Attributes on a 25 Point Buy system) and count how many times each number shows up.
Here's what the code looks like:
Code: #include <iostream> #include <ctime> #include <cstdlib> using namespace std; int Generate() { int r= rand(); int s= r%7; [Code] ....
So I have to ask the user to enter a positive 12 digit number, and it has to be 12 digits exactly. I thought I'd do
Code:
unsigned long long int x; do{...} while(!(x>99999999999 && x<1000000000000));
This would obviously be fine on my 64 bit machine, but the code will be ran on a 32 bit one, where unsigned long long is, if I'm not mistaken, 32 bits. Which has a max value of 4 billion and something.
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<fstream> int decryption(int); int multiply(int,int[][2]); using namespace std; main(){ int n; ifstream inFile; inFile.open ("out.txt");

I was trying to store numbers read from a text file into 2D array but I am getting the error above.here is where the error occurs:
I'm trying to write a program that generates a random number between 50 and 200. I made a program that generates random numbers, but how to make those random numbers be in-between 50 and 200. Any example of a program that generates random numbers that are confined in-between certain values?
I have a array that has 10 quotes inside, and I want to put a random number between 0 and 9in these -->[] , so that when I press the button a random quote will be shown.
private void Random_Click(object sender, RoutedEventArgs e) { string[] Quotes = new string[10]; // List with quotes Quotes[1] = "Life isn't about getting and having, it's about giving and being."; Quotes[1] = "Whatever the mind of man can conceive and believe, it can achieve."; Quotes[2] = "Strive not to be a success, but rather to be of value.";
