C++ :: How To Pick Random Number From Array

Oct 24, 2013

Basically we have this 7 bit binary code, and i would like to pick out 3 numbers randomly from it, how do we do that ?

for example 1011101

int Num[7];
for(int i=6; i>=0 ; i--)
{Num[i] = binary % 2;
binary = binary/10;}

C++ :: Random Pick Without Repeats

May 9, 2014

What I'm trying to do is to have the program pick random people for different jobs. The user enters the number of people, then, enters both jobs and the people's names. I need the program to pick random people, but randomly pick again if the person has already been picked, so, no repeats. I have the program picking random people, but I can't get it to not pick the person again. I'll run it and there will be no errors, but it's almost like Xcode completely bi-passes the for/if to check if it's picked the person already.

Below is the code.

#include <iostream>
#include <math.h>
using namespace std;
int main() {
int runagain=0, correctnames=0, versiondesciosion=0, correctjobs=0;//vars that make descisions for running again
rerun:

[Code] ....

Dont look at the "fun" version for the switch statement. It's not ready yet, I'm just having trouble with the random thing.

C++ :: Program To Pick A Random Name From A File With List Of Names

Oct 28, 2013

I just recently started looking into C++ programming so I don't know much.

I was wondering is it possible to write a program to pick a random name from a list of names, which are in a .txt file? or if I could ask the user to input the list of names and then let the program pick a random name?

C :: Creating Program That Can Pick Words In A String Or Array

Apr 24, 2013

Creating a C program that can pick words in a string or array and save it in different location, later combine everything in one string or array. It will be using simple programming C code. For example (arrays, pointer) but not interrupts or other string functions.

In a sentence like this:
Size= 70
$--GSV,x,x,x,x,x,x,x,...*hh $--GGA,hhmmss.ss,llll.ll,a,yyyyy.yy,b,x,xx,x.x,x.x,M,x.x,M,x.x,xxxx*hh $--GLC,xxxx,x.x,a,x.x,a,x.x,a.x,x,a,x.x,a,x.x,a*hh $--GSA,a,a,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x.x,x.x,x.x*hh

The program must capture the $--GGA string then extract from this string:

1) hhmmss.ss
2) IIII.II
3) a (if a = to N or S replace N or S with + or - respectively )
4) yyyyy.yy 5) b (if b = to E or W replace E or W with + or - respectively )

Save them in an array and display as well. After all the saving, the program should combine them to one string. That the final output.

C :: Random Number Generator Array?

Apr 6, 2013

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.

C :: Storing Random Number Into Array

Dec 16, 2014

Code:

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?

C++ :: Random Number Generator With Array

Feb 23, 2015

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.

C++ :: Game Of Pick 4 - How To Find Similar 4 Digit Numbers In Array Of 120

Jun 6, 2014

I have a question regarding finding similar 4 digit numbers in a pool of 120 numbers

Below is an linear single dimension array of 4 digits

There are 120, 4 digit numbers in total

My question is this - How can I code in C - a function that looks through all the 120, 4 digits to find similar numbers

Example - 2095 is similar or matches to - 0950, 5095, 5250, 5269 - i.e having 3 of the digits that are the same in the 4

The code must print out 2095 + all the matched numbers

If the Matched or Similar numbers are less then a certain number n - that number is discarded and the code should go onto the next number

2095095053741884864037233464846523768035

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:

2: Code:

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

When I run this program it always generates the number 41 or 42. Why is this? Even if I add the code

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

C/C++ :: Random Number Conundrum

Nov 3, 2014

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
