C :: Program Printing A Random Number Instead Of Variable

Mar 6, 2015

Program that has the user enter 5 digits then asks the user what they want to know about the 5 digits. My issue is when the program goes to print the value, its a totally ill related number

10 34 8 17 50

program prints out:

2 for smallest
79 for largest
119 for sum
23.80 for average

Code:

#include <stdio.h>#include <stdlib.h>
int main(void)
{
int smallNum, largNum, count=0, sum=0, value, choice;
double avgNum;
printf("Enter 5 integers
");
printf("
");

C++ :: Getting Random Variable At Every Start Of Program

Dec 29, 2013

My motive is to get random variable at every start of program. So it does not show same sequence when it run again and again

Code:
int main(){
srand( time ( NULL ) );
cout<<rand();
}

When i run this program in code::block the following program is opening with error in new tab called TIME.H

Code: /* * time.h

* This file has no copyright assigned and is placed in the Public Domain.
* This file is a part of the mingw-runtime package.

C++ :: Program To Generate Random Number Between 1 To 100 - While Loop Will Not End

Feb 21, 2014

My program asks me to write a C++ program that generates a random number between 1-100, and lets the user guess the number until he/she guesses correctly.

I have every thing done but my loop will not end. I know I have to "update" the loop to end it but I don't know what that means.

#include <iostream>
#include <iomanip>
#include <ctime>
using namespace std;

int main() {
srand(time(NULL)); //the function that generates random numbers

C++ :: Creating A Random Number Generator Program?

Aug 9, 2012

I'm trying to create a program that creates random numbers. I looked through some examples and this is what I came up with. The time identifier seems to be undefined yet I see no reason it is undefined.

Code:
#include "stdafx.h"
#include <iostream>
using namespace std;
int main() {
//Re-seed the random-number generator
time_t now;

[code]...

here's my error code..

C/C++ :: Printing Partitions Of A Number Using Constraint On Number Of Values?

Apr 15, 2014

I'm taking a C++ computer science course right now, and one of the questions on my latest assignment is this:

"A partition of an integer n is a way of writing n as a sum of positive integers. For example, for n=7, a partition is 1+1+5. Write a program that finds all the partitions of an integer n using r integers. For example, all the partitions of n=7 using r=3 integers are 1+1+5, 1+2+4, 1+3+3, 2+2+3."

I've been struggling with this problem for a couple days now, and how to do it. I understand I need a recursive function to grab variables, and probably an array or vector to store them, but where to begin.

I've been reading documents on partition generating and the concept still eludes me, and any other questions on here or other programming sites using partitions don't seem to have a constraint on them.

C++ :: Random Number Generator - Count How Many Times Each Number Shows Up

Sep 26, 2012

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] ....

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

2: Code:

14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 Stats[0]= 0 Stats[1]= 0 Stats[2]= 0 Stats[3]= 0 Stats[4]= 25 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 Stuck On 1 Number?

Nov 21, 2013

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.

Code:

#include <iostream>
#include <iomanip>
#include <cstdlib>
#include <ctime>
using namespace std;

C++ :: Random Numbers Between 1 To 5 For Variable Of 5 Arrays

Sep 14, 2012

I want to have the random numbers between 1 to 5 for a variable of 5arrays. for having the random numbers i am using the code as below.

Code:
for(int i=1;i<=5;i++)
{ int j=rand()%5;
cout<<j<<endl;
}

The problem with this way of generating random number is that i get the same set of random numbers in every outputs. Is there any other way to have different random numbers with many different outcomes as much as possible.

C++ :: Variable Initiation - Calculate Number Of Multiplications It Took To Reach A Certain Number

T power3(T x, unsigned int n, unsigned int& mults) {
if (n == 0) return 1;

C++ :: Printing Permutations Of Digits Of A Number?

Feb 8, 2013

I have been trying to write a recursive function to print the permutations of a n-digit number. This is the logic that i am trying to use.

1.call the permutation function,

2.keep the first digit in the first place and send the remaining 2 digits back to the permutation function recursively.

3.keep one of the two digits received and send the remaining digit to the permute function.

4. keep doing this till only one digit remains. this is the smallest solution so return it.

C/C++ :: Random Number Is Always 41 Or 42

Nov 11, 2014

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

#include<iostream>
