C :: Break Statement In Random Number Sorting
Jul 4, 2014
The program I am stuck on is used to generate random numbers, then sort them (found in Chapter 23, p. 212). When I compile it, I get an error stating "break statement not within loop or switch. I'm finding that there is an issue with a break statement, but I don't know enough yet.
Code:
/* Will generate random numbers, then sort them.*/
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
main() {
int ctr, inner, outer, didSwap, temp;
int nums[10];
time_t t;

I am writing for loop with a switch so that scores can be inputted in by a judge. The issue that I am running into is that I will put out an the text then the test happens and the code puts out the switch statement 5 times with random number. Here is what I have written.
Code:
int main() {
int diver;
int option;
int Judge;
cout << "Enter Divers Name:";

I have an exercise that asks me to print numbers at random from the following set (using only a single statement):
2, 4, 6, 8, 10
Here's my statement:
Code:
cout << (2 + rand() % 9) << " ";
which prints numbers at random between 2 and 10, now I can use the modulus operator in an if...else statement to print only even numbers but the exercise specifically requires using only one statement, can that be done using the conditional operator? and if not then how?

I am working on a small simple program my program fills up a air plane with customers there is 2 levels 1 and 2 and it will put that person in the spot depending on being picked.
So far i made a boolean airplane with 10 spots I can enter 1 person into the airplane with no problem but then after he sits down i get a infinite loop? I assume i maybe have to use the continue statement I feel like there is something simple that im missing i want to add more people. here is what i have
class Program
{
static void Main(string[] args)
{ bool[] planeSeats = {false, false, false, false, false, false, false, false, false, false };

I am having some problem with my quick sort problem. My program is supposed to create 5 arrays with 5,10,15,and 20 random integers, respectively. Then it should sort those arrays, where the numbers are bigger or smaller than the middle element in the original array! The program I wrote should do that but, its not! The program just keeps running infinitely!
#include <iostream>
#include <cstdlib>
using namespace std;
void p(int k[],int left, int right) {
int i = left, j = right;

I tried to sort a large numbers of vector of random integers with std::sort(), but when the number increases over 10M, std::sort returns all zero in values. Does std::sort have a limitation of input numbers?

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.

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;

is there a to use printf to print certain number of blank spaces, where the number is derived from the output of a function?
for(m=low; m<=high;m++)
{
printf("t=%2d %'f(m)-1's %3c
", m, ' ',*);
}
this is suppose to output
t=-3 *
t=-2 *
t=-1
.
.
.
This is supposed to output t=m and then m is plugged into a function say for -3, plugging it into function f gives 23, well i want 22 blank spaces and then a asterik and go to next line. that is why i put -1 after %'f(m)-1's i
The asterisk appear right next to the t value here but they are way to the right of it when i made this post.

So I tried creating a test code for reading a negative number and positive number but whenever I enter a negative number it read it as being positive.
#include <stdio.h>
#include <iostream>
#include <iomanip>
[Code].....
PS: I am using char over int because the program that I am testing for requires me to use 8 bit variable.

I am a beginner at C++, the output is pretty self explanatory. I'm trying to make a number sorting program with other features, but the numbers are all wrong.
Code:
#include <iostream>
#include <iomanip>
#include <fstream>
using namespace std;
[Code] .....
Input.DAT
Code:
376 389 450 735 600 576 612 700 450 628 778 389 667 500 475 550 687 791 829 344
549 476 400 587 535 657 789 583 340 764 422 826 566 436 565 834 533 423 837 701
847 521 746 356 582 465 493 593 425 421
I can't for the life of me figure out why the numbers are all messed up.

make my program sort data.in this case number that i declared as char(not string, my bada)if i have
name1
number 2500
email
name 2
number 2400
email
i need to put that this way:
name 2
number 2400
email
name1
number 2500
email
i saw that can be done with qsort but when i try it it doesn't work.
Code:
typedef struct {
char nome[MAX_GERAL], email[MAX_GERAL], morada[MAX_GERAL], postal[MAX_GERAL], numero[MAX_GERAL], geral[MAX_GERAL];
int telefone, FP, SD, AM1, ALGA, CM;
}dados;
code to add info i need to sort "numero"
Code:
void adicionar(dados* contacto){
if (i<total) {
printf("
Introduza o Nome: ", i + 1);

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>
#include<cstdlib>

I was wondering if there is a way for me to break up a word compare it one character at a time and change it according to a real word like if you have cat and dog it would go from cat to bat, bat to bag, bag to bog, then bog to dog.

I have a random number generator that should genetate 2 numbers between 100 and 0. The first number works fine but the second doesn't, why?
i1 = random() %100;
i2 = random() %100;
while(i1 < 0 && i1 > 100){
if (i1 < 0)
i1 = i1 + random() %100;

I'm making the n puzzle game (15 puzzle), but having a problem generating random numbers without the duplicates.
Random num = new Random();
int rand = num.Next(1, 15);
b.Text = rand.ToString();
eliminating the duplicate numbers and only allowing 1-15 once in each button.

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

I made a function that provides random number to a matrix. The function works fine but with one problem, every time i call the function it provides the same numbers to every matrix.
void randomMatNumbers(int **p, int rows, int cols) {
int i, j;
srand(time(NULL));
for(i = 0; i < rows; i++) {
for(j = 0; j < cols; j++)
p[i][j] = (rand() % 199) - 99;
}
