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
I have to write a C++ program that picks a random number between 0 and 49. If the number is even lets say 30, then the computer will display 30, 32, 34, 36... all the way till 100, if its odd lets say 17, then the computer will display 17, 19.. till 99. I got the computer picking a random number, I just can't figure out how to display every other number using a for loop statement. Here's my code for random number generator:
#include <iostream> #include <cstdlib> #include <ctime> using namespace std; int main()
I'm trying to write a program that generates a random number between 50 and 200. I made a program that generates random numbers, but how to make those random numbers be in-between 50 and 200. Any example of a program that generates random numbers that are confined in-between certain values?
So I have to generate a random number between 1 and 6 and then store that same random number into an int variable. Eg, if the random number is 4, that must be stored into int i.
I've been currently stuck on a C++ problem. Here's the question:
Write a program that generates one hundred random integers between 0 and 9 and displays the count for each number. (Hint: Use rand()
% 10 to generate a random integer between 0 and 9. Use an array of ten integers, say counts, to store the counts for the number of O's, l 's, . .. , 9's.)
I think I'm pretty close, but I keep on getting "0" for the occurrences (or counts) of each random integer.
#include <iostream> #include <cstdlib> #include <ctime> #include <conio.h> #include <fstream> using namespace std; const int SIZE = 100;
so I'm creating a program that generates random sentences with structs..I'm trying to use structs and and create 4 different groupings article, noun, verb, and preposition. Then I'm trying to use "r = rand() % ;" to randomly pick one one word from each group to make a sentence. this is what i have
Code:
typedef enum article { the = 1, a, one, some, any } article; typedef enum noun { boy = 1, girl, dog, town, car }
I've researched this quite a bit and the overwhelming answer I've been seeing for a loop generating the same pseudo-random number is that you're seeing the random number generator inside the loop, but that is not the case with me . . . At least not that I can see.
Basically, as I mentioned, I have a loop "birthing" new bunnies in a loop. And all the new bunnies are being created with the same name and other details.
Here is the code:
void BunnyGraduation::breed() { for (unsigned int male = 0; male < colony.size(); male++) { if (colony.at(male).getSex() == Bunny::Sex::MALE && colony.at(male).getRadioactiveMutantVampireBunny() != true && colony.at(male).getAge() >= AGEOFCONSENT) { for (unsigned int female = 0; female < colony.size(); female++) {
[Code] ....
srand(time(0)); is seeded ONCE in the constructor of the bunny object itself. . . Now, come to think of it, the constructor is called every time an object is created . . . And the constructor contains the srand() . . . and the constructor is being called in a loop. . . So therefore, yes, the srand() is being called inside the loop.
I'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.
i wanna no if i can make the program generate a different number everytime you guess the number right and want to play again. it always generates the same number
I need to write a lottery program that generate 5 non duplicate number between 1-20. Below is my code and it said my [i] is undefined and it is an undeclare identifier.
#include <iostream> #include <stdlib.h> #include <time.h> #include <iomanip> using namespace std; int main(){ srand(time(NULL));
Write a program that will generate, but not display, a three-digit "target" number that has three distinct digits. (Hint: use random number generator.) Then, input a maximum of ten user guesses and for each guess, output the number of hits and matches in the guess. Stop when the user guesses the number or runs out of guesses. For example, if the target is 427, the guess 207 has one hit (7) and one match (2).
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:";
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
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..

I'm trying to generate random numbers so that I can assign people to teams. So far I have come up with this
Code:
int generateTeam(){ int i, teamNumber, c, n; for (c = 0; c <= 5; c++) { n = rand()%100 + 1; }
[code]....
}//end generateTeam I'm not sure how to make it so that I can exclude the previous random number when generating the next one. As an example, I have 22 students and I get the number 19. Now I can't have 19 again because that guy already has it.
The program is to generate random numbers to a file and will have one integer parameter, Open a file and then using a loop write the required number of random numbers to the file. Scale the random numbers from 1 and 100 inclusive. Then closes the file .The last function will read the numbers in the file into your program. so far i have
I want to print different color names for "nb " times . I get the number " nb " from the user or from text file . if " nb = 3 " then I want to print any 3 different color names which means that I may print ( red , green , blue ) for example . and if " nb=5 " then I have to print any five different color names ( pink , blue , black , red ,white ) fore example .
Note : " nb " may be a large number ( 17 for example ). How can I do this ?
