I need to create an array and fill it with numbers from 1 to 15. The below array must return values randomly from 1 to 15 without any repetition.
Code:
public int[] getRandomNumbersForGrid() {
int arr[] = new int[15];
return arr;
}
any hints regarding trimming the number and returning random values.
This works, if just loops through till it doesn't find a space or tab than counts the index at that point then uses substr to get rid of any spaces/tabs, it's a small function and uses a goto. how to do it?
Code:
string trimLeft(string lineOfCodeToTrim){
string l = lineOfCodeToTrim;
int k =0;
for(UINT i = 0;i<l.length();i++){

How to do the problem below using loop?
Input numbers until the user types a 0, then output the product of the non 0 numbers: e

User enters sentence "The Smiths have two daughters, three sons, two cats and one dog." (The numbers may change depending on what the user chooses to enter. He told us the range would be from zero to nine.) and we have to convert the written numbers within the sentence into actual decimal numbers and print out the new sentence. Ex. The Smiths have 2 daughters, 3 sons...etc.
I have written the following bit of code which reads the string and finds all the "written numbers" but I am not sure how to proceed from there. I am stuck on how to print out the new sentence with the converted numbers as my professor mentioned something about creating the new string using dynamic memory allocation.
Code:
#include <stdio.h>#include <string.h>
int main () {
char A[100];
int length = 0;
int i;

The input file has the numbers 1 & 100.

I need a list generated of all possible subset combinations for the set 1,2,3,4,5,6,7,8,9,10,12. Select six. Numbers cannot repeat.
Example subset: 1,2,3,4,5,6 (six selected, no repeats).
Example of what I dont need: 1,1,2,2,3,3,4,4,5,5,12,12 or 1,1,1,1,1,6.
I will also need the opposites removed, meaning...if I have 1,3,5,7,9,11 then I need 2,4,6,8,10,12 eliminated from the final list.
This is for a game, where you must select all numbers right or no numbers right.
The code below will generate combinations of numbers from 1 to 25 in an 15 numbers array. The only filter I've applied is that the sum of all the numbers in the vectors divided by 15 needs to be between 13 and 14.
I would like to count how many consecutive numbers there are in one combination, so that later i can apply another filter.. for example:
1 3 4 5 6 8 10 13 14 16 17 18 19 20 25
3 + 4 = 1
4 + 5 = 1
5 + 6 = 1
13 + 14 = 1
16 + 17 = 1
17 + 18 = 1
18 + 19 = 1
19 + 20 = 1

Count = 8, in this case..

So i have made an array and made a scanf in a for loop so it can store all numbers entered from keyboard in the array but i dont know how to put the numbers that are less than 5 in another array and then print that array out and the lenght of the array.

Write a program which reads a stream of numbers from a file, and writes only the positive numbers to a second file. The user should be prompted to enter the names of both the input file and output file in main(), and then main() will open both files. Another function named process() must then be called to read all the numbers from the input file and write the positive numbers to the output file. Note that you must pass the open stream variables for each file as arguments to the process() function, and that you need to (always) double check that the files opened successfully before using them.
This is what I have so far but its not working out!

All Numbers are random.
This will be the output

The Sum of all odd numbers is 4
i have trouble with comparing two of the biggest numbers out of four numbers. Im working on an assigment with a dice game where i need to tell the computer the following;
"if the biggest number out of dice_three and dice_four is the same number as the biggest of dice_two and dice_one, then loop1=true"
this is how i have been writing it so far ;
if
(MAXA(dice_three,dice_four) == MAX(dice_two,dice_one)){
lopp 1=true;
}
(as seen) i am using:
#define MAX(dice_one,dice_two) ( (dice_one) > (dice_two) ? (dice_one) : (dice_two) )
#define MAXA(dice_three,dice_four) ( (dice_three) > (dice_four) ? (dice_three) : (dice_four) )
to calculate which one is the biggest number out of the two pares. The code i have been writing so far seem to have the wrong syntax.
If I have the number 88 how would I add 00 to the end of and turn it into 8800? Bitwise shifts is the only way I can think of to do this but it doesn't work. It completely changes the numbers.

View 5 Replies View Related is there anyway to have a program where it ask for three numbers and you shows which which number is the largest and which is the smallest, e.g.
Enter 1st number: 30
Enter 2nd number: 10

Largest = 30
Smallest = 10

when I ran the program , I got "4" with prime numbers. I only way I was able to remove the "4" was this "num!=4".
Well I've given myself a lil project and I can't seem to figure out why the numbers keep repeating. What is the cause of this repetition. the function that generate the numbers is below
Code:
void numGen(struct Ticket *pick){
int x;
int y;
int check = 0;
[Code].....
This part of the code i suppose to get generate all possible combination of number and numbers and combination can't repeat. There 6 set of numbers the first 5 can't repeat, here is what I have so far. Its not efficient and is time consuming for my PC. probably will take upto 10 minutes to complete.
Code:
void Gen2(int limit){
FILE *fPtr;
struct Ticket set;
struct Ticket nSet;
struct Ticket checkSet;
int pass;

The repeatCheck function returns the correct value but is just repeats constantly.
