C++ :: Random Number Generator - Count How Many Times Each Number Shows Up
Sep 26, 2012I'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] ....
And here's two outputs.
1: Code:
12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 Stats[0]= 25 Stats[1]= 0 Stats[2]= 0 Stats[3]= 0 Stats[4]= 0 Stats[5]= 0 Stats[6]= 0 Stats[7]= 0 Stats[8]= 0 Disallowed system call: SYS_socketcall

Note that the number does change, but only between runs.

C :: Random Number Generator Array?
Apr 6, 2013Write 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.

Feb 23, 2015The 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

Aug 28, 2013I have to come up with a program that I have to create which is: The Computer guesses a random calculation "Value1 Operator Value2 = Answer." The computer randomly displays two of the four objects. The Player must guess the remaining two objects. If the player gets one right then the computer says "one is right." The game should continue until the user has provided all the correct calculations.
This is what I have, BUT I have 2 errors.

C :: Random Number Generator Inside / Outside A Loop?
Nov 15, 2013I've been working on a program on and off for around a week now and I've been struggling towards the end of the program.First of all, the program is a maths quiz which generates two random numbers per question.I'll give you one part of my code:
Code:
srand ( time(NULL) ); //seeds the random number generator
int score = 0;
int a = rand()%12 +1; //generates a random num between 1-12
int b = rand()%12 +1;
int c = a+b;
int d;
}
[code]....
I've basically copied the above code 10 times and changed the variables by going through the alphabet e.g.
Code:
int a = rand()%12 +1; //generates a random num between 1-12
int b = rand()%12 +1;
int c = a+b;
int d; all the way to
Code:
int an = rand()%12 +1;
int ao = rand()%12 +1;
int ap = rand()%12 +1;
int aq = an+ao-ap;
int ar;
Now what I'm going to do is remove all the declared variables and create a loop. But my problem is; If I wanted to declare four variables for e.g.
Code:
int a = rand()%12 +1;
int b = rand()%12 +1;
int c = rand()%12 +1;
int d = a+b-c;
Would I place the srand( time(NULL)); inside the loop? it's confusing because I know an example of a basic loop with an array would be:
Code:
#include <stdio.h>
#include <conio.h>
int main(void)
{
int test[5]={21,18,47,21,4};
int I;
int total=0;
for (I=0;i<5;i++)
total += test[I];
}
[code]....
how or where to include the random number generator in the loop and to make it ask 10 questions at random.

C++ :: Random Number Generator - How To Get User Inputs
Sep 10, 2013I want to program a program that produces a random number between 1-10, then if the number is correct, says like HEY GOOD JOB and if its not says try AGAIN! also, at any point the user can quit by typing in X.
I know that I can use stuff like cout << "Hey put in a guess now" to prompt the user but I dont know how to accept inputs.
For example, how do I use scanf to do this?
I know that if I use scanf, it takes in a value, but where the heck does it store it?
eg. scanf(%s,guess);
Is that valid? I get an invalid expression error when trying to use that in C++.

C++ :: Random Number Generator Stuck On 1 Number?
Nov 21, 2013I 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.
Code:
#include <iostream>
#include <iomanip>
#include <cstdlib>
#include <ctime>

C++ :: Random Number Generator Isn't Working Correctly - Ignoring Conditions
Apr 12, 2014My random number generator isn't working properly. It seems to be ignoring my conditions when it compiles and I enter the input. The program is supposed to accomplish the following.
1. Let the user input how many digits he or she would like to have in the random numbers.
2. Let the user type in how many of the numbers that he or she wants.
3. It will then generate the numbers.
4. It will display the minimum or maximum number it can be with the number of digits the user entered. And display the number of numbers that the user wanted. It also is supposed to check and output only up to the max of that digit range.
so if someone entered they wanted a digit of 1(1-9) but said they wanted 300 numbers it would only output 9
Example:
the user says that she would like 3 digits to be in the numbers generated. So it will output numbers between 100 and 999. then the user says that they would like only 3 random numbers. So it will output three random numbers in between 100 and 999. Also all of the numbers need to be unique so they can't output more then one of the same number.
I am not sure why but it ignores my conditions. Ill type that I want 7 but it just outputs a bunch of random numbers. it dosen't stay in the ranges.

#include "stdafx.h"
