Iam new to c++ and i want to write a program to generate an integer array. I keep getting the error at line 25: invalid types 'int[int]' for array .
int main() {
int rows;
int cols;

Write a C program that sorts an unsorted array of 5 integer numbers in ascending order by swapping numbers repeatedly. Specifically, first prompt the user to input 5 numbers and store the numbers in an array. Then, if the numbers in the array are not in ascending order, ask the user to provide the indices of two numbers in the array that the user wants to swap. If the user does not enter valid indices (i.e., outside 0 to4), then re-prompt the user to enter new indices. Continue prompting the user to provide indices of numbers to swap until the array becomes sorted in ascending order. Finally, when the array becomes sorted, the program should print "The array is now sorted in ascending order".
Implementation Requirements
Use the #define directive to define the size of the array.
Implement a function called "checkArrayOrder" to check whether an array is in ascending order or not. The prototype of the function is
"intcheckArrayOrder(int arr[], int size);". The function should return
1 if the array passed to the function is in ascending order0 if the array passed to the function is not in ascending order
Define the function prototype in your program.
Implement a function called "swap", whose prototype is "int swap(int arr[], int size, int i, int j);" which swaps the numbers in positions "i" and "j" of the array passed to the function and returns
1 if the indices"i" and "j" are within bounds (i.e., between 0 and 4) and the swap operation is performed correctly.
0 if the indices"i" and "j" are outside bounds so that the swap operation cannot be performed.
Define the function prototype in your program.
Use the function "checkArrayOrder" whenever your program needs to check whether an array is in ascending order or not; and the function "swap" to swap the numbers the user specifies (Note that, you should check whether the user provided indices are valid inside the function "swap" and not inside "main").
here is my code so far
Code:
#define ARRAY_SIZE 5
void main()
{
int i, array[ARRAY_SIZE];
printf("Enter %d numbers
", ARRAY_SIZE);
for(i=0; i<ARRAY_SIZE; ++i)
scanf("%d", &array[i]);
[Code] .....
I'm just not sure how to proceed. I'm not really sure how to progress the checkArrayOrder function to the swap function (in the if statement).
I am trying to assign the integer value to unsigned char array. But it is not storing the integer values. It prints the ascii values. Here the code snippet
Code: uchar uc[100];
for(i=0;i<100;i++)
{
uc[i] = i;
}
The values which are stored in uc[] is ascii values.I need the integer values to be stored in uc[]. I tried to do it with sprintf. but the output is not as expected. if I print the uc[i] it should diplay the value as 0,1,2....99.
I try to write my data into two different files and i just use something like this
ofstream myfile;
myfile.open("phase 1.txt");
if (myfile.is_open()) {
for(i=0;i<M; i++)
[Code] ....
But it only generate the first file. How should i modify this?
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 have wrote code that has three functions, one to print the month, one to print the days in month, and one to find if it is a leap year or not. I have gotten up to the point where I can print the 12 months with a for loop, but how to print out the days in the format above.
This is my code.
#include <iostream>
using namespace std;
void printOneMonth(int month, int& dow, int year);
void daysInMonth(int month, int year, int& dim);
bool isLeapYear(int year);

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.

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).

It should look like this (just pretend all the numbers are lined up in their respective columns)

I am trying to generate two arrays from one big array, of which the sum of the 2 array's elements are as close to equal or equal to each other if possible, or one array summed up minus the second array summed up will be as close to zero as possible. I start with int array of 30.
It says that the lowest possible combination of one array minus the other is 239 which I know is not true. Also this needs to run in under ten minutes.
#include <iostream>
using namespace std;
const int size = 30;

I have been writing a program to generate pairs of RSA keys using small prime numbers. I have been using mpz_invert() to get a value for d for the private key. On small prime numbers it calculates the correct value, but on larger primes it calculates incorrect values.
I'm assuming there must be an upper limit to the values the mpz_invert() function can handle? If so, what is this limit to avoid erroneous values?
I'm currently working on assignment which requires to generate a random permutation of the first N integers. For example, if N = 4, one possible answer is {3,1,2,4} without duplicates. {3,3,2,4} is not correct
to fill a[4], generate random numbers until you get one that is not already in a[0], a[1], ..., a[n-1]. for a[0] whatever random number you generate can be put in it. So here is my code. It seem to works but sometime it give duplicates.

My program generates an array of random numbers. I want to then search a specific number within the array. If the number is in the array then a message apopears on the console saying that its there. I'm using the binary search algorithm to do this.

#include <iomanip>
#include <cstring>
using namespace std;
int size;
int getSize() { return size; }

When you have constant arrays, they are stored in the programme memory space. Upon execution, they are copied into the data space for easy access. To save space in the data space, it is possible to stop it from being copied. Some compilers will deal with this by just specifying the array as const, g++ has a type modifier called PROGMEM.
In any case, the problem is that I'd like to generate some data, preferably without using an external programme to do it. Hence, my question using the template system. Now I could possibly use macro metaprogramming via boost instead of template metaprogramming, and I may have to go that route. However there are limitations, especially since its numbering system is only equivalent to an unsigned byte, which I possibly could use, but could become more messy than if I use the template system that has long long types as well as a whole slue of type safety mechanisms.
