I do not have code - I am just wondering if I have a method which gets input from the keyboard and returns it, how would I store that information in a new method after calling it and put the result of it into an array.
View 3 RepliesI am trying to compare 2 strings of characters The users input containing 5 chars is compared to a table If the input is already be existent in the table the index of those chars in the table is printed Quest: how to copy the result of a printf() into an array ? The last printf() gives a sequence of numbers and I am trying to save that sequence to another array for further operation ! I have not been able to do that so far even with tmp[]=i ;

#define N 30

i use dev c++...i write this code to reverse an array and save the result in the same one
if n=3 i expect
a[0]=0 a[1]=1 a[2]=2 (before rev is OK but after calling rev)
a[0]=2 a[1]=1 a[2]=0 (expected result )
but i get
n=3

node = pool.at(0) is executed even though pool is empty,
I even tried pool.size() == 0, that line is still executed. What is the reason, I wonder?
Code:
NodePoolNode* NodePool::acquireNode(int x, int y, long t) {
std::stringstream key;
key << x << ":" << y << ":" << t;
NodePoolNode* node = usedNodes[key.str().c_str()];

I am trying to print the array of string using this code but the compiler is printing null in the output:
The code is as follows:
char *arr[10];
int i;
for(i=0;i<10;i++)
scanf("%s",*(arr+i));
for(i=0;i<10;i++)
printf("%s

I've been trying for more than one month to access a method found in a library called libcocosnas_static.a. I'm using Cocos2d-X version 2.0.4. The library has been used many times by my company to make games using cocos2d-1.0.1-x-0.12.0 without any problem.
This is what I've done:
1- I added the include paths of the library to both eclipse and Android.mk
2- Included the .h file using #include "NASPlatformUtil.h"
3- Added the libcocosnas_static.a file to the proj.androidobjlocalarmeabi folder
4- Added "LOCAL_WHOLE_STATIC_LIBRARIES += cocosnas_static" to the Android.mk file
5- Called the function using: NASPlatformUtil:: openUrl("http://xxx.xxx.com/");
I can right click on the function, click Open Declaration and get it without any problem, but the compiler keeps on giving me that dreaded error...
Is it possible to prompt information from user then display the result in a one dimensional array form? If yes, how should i link them together?
View 7 Replies View RelatedI have to create a program that accepts 10 numbers from user, and then I display a list of the numbers, the smallest one and the higher number. I have problems with displaying the smallest and higher number, I tried to Array.Sort and Array.Reverse, but I don't know what I'm doing wrong, this is my code:

I have one array with size of 5 and passing this array to one method. I want to get size of the array inside method. If i get size of array inside method, i'm getting only "1",but not "5".
int v[5];
v[0]=1;
v[1]=2;
v[2]=3;
v[3]=4;
v[4]=5;
cout<<sizeof(v)/sizeof(&v[0])<<endl; // here i'm getting size as 5
CreateArray(v);
void CreateArray(int val[])
{
cout<<sizeof(val)/sizeof(&val[0])<<endl; // here i'm getting size as 1
}
Is there any way to get size inside method ?
I have to create array with size that returns from method
int val=test();
int arr[val];
int test()

I have the following method:
public string[,] StringConvert_tblVFWPost(DataTable dt1) {
string[,] stringArray = new string[dt1.Rows.Count, dt1.Columns.Count];

for(int col = 0; col < dt1.Columns.Count; col++)

The error I'm getting is "Cannot implicitly convert type 'string[*,*]' to 'string'". So that tells me what the issue is. However, I'm not sure how to fix it.
How do I change this method, so that it properly returns my two dimensional array?
The program should store a character array in reverse order then display the reversed array. I have also included in the code that will display the actual characters into the array as it loops through. So I know the characters are being stored, but why doesn't it display the entire string when I call it?
Code:
#include<stdio.h>
int main(){
char str[50];
char rev[50];

I am trying to sort an array of random numbers by passing it to a method Sort(), sort the array, and then pass the entire array back to the calling program. Each time I run this though, the array doesn't seem to sort. I'm not sure if the problem lies with my sorting algorithm or if it has something to do with calling the function.

View 1 Replies View RelatedI have a question similar to the one here: [URL] .....
The main difference is I would like to pass a method of derived class as a parameter to some other method in its template base class.
template <typename BaseType>
class Base {
public:
typedef void (Base::*Callback)(int A);
[Code] .....
The above is an example which does not compile. My compiler complains that the two BaseMethod() calls in DerivedMethod() are invalid uses of non-static member function.
Is this not possible to do, or is my syntax simply wrong? All I want is to be able to pass as an an argument to a method in the base class from the derived class some callback as a variable for the base class to invoke later.
How can I store this data into an array?And I only can read the first integer.. 10.... How can I read the whole file...Heres the data:

I am working on an assignment for class: Create a program that allows a user to enter up to 10 addresses of friends. Use a two dimensional array to store the address of friends. After each address is entered, the user should have the option to enter another address or print out a report that shows each addresses entered thus far. I have created a code that is coming up without errors, but i am not getting the desired results.
Code:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
int main ()
{
char name[10][10] = {0};
char address[10][10]= {100};
int choice;
[Code]....
My trouble is coming from the the output. I am able to fill the array but i am not able to print my desired results. Where am I losing it in the loop? Also after my first entry if i have space in the "address" input the program prints and ends.
I have this data store into a data structure.

data and then i have an array /*! it contain group_id of each data line*/ int group_id[16]={0,0,0,0,3,3,1,1,1,3,3,2,2,2,2,1}; I never worked with 2D array before. My problem is that i want to create a 2D array of that data for example if i write data[j][i].. It will give me the reference/value of all data lines that belongs to j column, and same with group_id[j][i]. I don't know how i can store these structure vaules in this like 2D array.

I think I'm getting the wrong idea about strings. I thought I could add data just by using '+=' but apparently not.
Can names and numbers be stored in one array ? Like a telephone directory?
View 1 Replies View RelatedThis program works but i need to build an additional loop that will re-prompt a user if his initial entry (int y_n) is other than 'Y', 'y', 'N', 'n'. For instance if a user tries to enter 'Yup', he will be prompted "That isn't a valid entry" and then re-asked to enter int y_n.
Note: If user answers Y he is asked to enter a value that is entered into an array. If the user at any point answers N, the program ends and final stats are cout.

I'm trying to design a C program that ask the users to type their full name (seperate by a space), and store this name in a two dimensional array. I just want to test if I did it correctly, so i just entered one name and give it a try.

printf("enter the neame");
scanf("%s%s",&name[0][0],&name[0][1]);
printf("%s",name);
return 0;

I am just trying to make a simple two player game. First player enters the movie and second player guesses it by using some basics of C++.
movie[] = entered by player 1.
movie_temp[]= a temp array with '_' in it. It updates after every guess by player 2.
MY PROBLEM: Please refer the main function where I called the function movie_check().
This updates the life after every guess. I want the same to happen for my movie_temp array.
When i run this program, only the lives are updated properly, on correct guess the lives are not reduced, but in next turn the array_temp is not updated and the same array is displayed again and again after each gas.
How to create a function which return array and save it in movie_temp (just as I did for life).
