C++ :: How To Assign Array To Every Element Of Another Array
Mar 29, 2014
I have been given an assignment which I understand pretty well, but I have a problem, and haven't been able to find a clear solution anywhere. I'm sort of a beginner in all this, so it's hard to understand what some people say.
So basically what I wanna do is assign a set of grades to every element in an array of a set number of students. I already have the part where you ask for the number of students you want to enter and then ask for their names and grades, but it can only enter one grade, and I can't figure out how to assign several grades and then get the average.
Here's my code, the assignment said to do it like this.
#define MAX 100
#include<iostream>
#include<stdlib.h>
#include<string.h>
[Code]....

I got this program to create an array of playing cards and assign the values and suits and shuffle the array. I'm at the point where I need to output the cards but I need to burn the first card by making it output "**" instead of the card. my cards[] is a constant so I can's assign the first card as such.
void showCards(const int cards[], int numCards, bool hideFirstCard) {
if (cards[0]) {
hideFirstCard=true;
cards[0] = '**';
} for(int a = 0; a <= numCards; a++) {
cout >> showCard(cards[a]);
} }

Write a program using user-defined function which accepts an integer array and its size as arguments and assign the elements into a two dimensional array of integers in the following format: If the array is 1,2,3,4,5,6, the resultant 2D array is
1 2 3 4 5 6
1 2 3 4 5 0
1 2 3 4 0 0
1 2 3 0 0 0
1 2 0 0 0 0
1 0 0 0 0 0

Why would you ever assign a pointer to an existing array?Take this link for example. URL....I understand that pointers use dynamic memory allocation so they are much more flexible then a built in array, but if you already have an existing array, don't you already have static memory allocation for that array? Why bother assigning a pointer? Regardless of the pointer, doesn't the program still allocate static memory to the array anyway?

How to assign numbers stored in a buffer memory to a 2D array.
The data type is unsigned 16bit (unsigned short) integers and they are stored in a 16bit/2bytes*1280*1024=2621440 bytes memory. The pointer pBuffer is the starting address of the buffer. Now I initiated an array and then assign the numbers to the array.
Code:
unsigned frame[1280][1024];
for (int i=0;i<1024;i++){
for(int j=0;j<1280;j++){
frame[i][j]=(*(unsigned short*)pBuffer+1024*i+j);
printf("%u ", frame[i][j]);
}
printf("
");
}
Because I know the number in the memory, I know after running the code that the result gives me nonsense.
I tried frame[i][j]=(*(unsigned short*)pBuffer+1024*2*i+2*j);
Since I think the pointer needs to move 2 bytes at a time, but it still gives me nonsensical array back.
Am I using the wrong expression to assign the values?

typedef tr1::unordered_map <string, pin *> pin_cmp;
pin_cmp _pin_cmp;
_Pins[_num_pins] = new pin (pin_id, _num_pins, s, n, d);
_pin_cmp[_Pins[_num_pins]->get_name ()] = _Pins[_num_pins]; //performance profiling
What actually the code doing?
_pin_cmp[_Pins[_num_pins]->get_name ()] = _Pins[_num_pins]; //performance profiling
I am not familiar with unordered_map which still can use with array[].I am confuse unordered_map just need key and value why will have array[]?

STRING s1 = “FOOBAR”
Here STRING is a user defined class. how to assign a constant char array "FOOBAR" to string object? Copy constructor need to be same class type as parameter. and overloading assignment operator also need to be same class type. I think 'friend' can let pass another type of object rather than STRING to do operation on overloaded '=' operator. How could it be done if it is possible at all?

My code has been acting odd. I made a function that layers my art resources but only the last tile of my art resource acts the way it should. My character goes behind and in front of the last tile and gets printed correctly. Strangely its really exclusive to the last tiles I print. What I need is to figure out in step by step order what going on with my code sample below and be able to layer the resources.
Here is a small sample of my main function. This is how I do my rendering.
Code:
Int main (int arc, char* args[]) {
//Move class
Move character;
//Class Tile & Side Tile
Tile *tiles [TOTAL_TILES];

I want to a C program to delete an element from an array which can use both index method & character method
For example
input : "1 222 333 4444"
output:"1 22 333 4444"
if either index = "4" or character ="2" is entered
It should able to read in/accept any input array of varying length, and the position/index or element in array to be deleted...

how to delete an element(s) from an array; suppose I have an array x[10] = {1,2,3,4,5,6,7,8,9,10}, and I want to delete array{5} so that the values of the array become {1,2,3,4,5,7,8,9,10}; how do I go about this? This is not the same as setting the value of array{5} to null; but completely eliminating it so that it does not get printed alongside the other elements of the screen.

How would I go about having a pointer to an array element specificity a character in a c-string.Every thing I try will not even build.An array is already a pointer to the first location of the array right?
char *pHead;
char *pTail;
pHead = sentence[0]; <=== This wont build
pHead = &sentence[0];
pHead = sentence[0]*;
*pHead = sentence[0]; <===== this builds but is not storing anything

"Write a program in C that finds the element of an array which all the previous are smaller and all the next are bigger than that.If there are more than one print the biggest. If there isn't any print "ERROR" .
EXAMPLE
If the array has 10 elements like this : {2,3,4,6,5,7,8,10,9,8}
The correct answer is 7 , because 2,3,4,6,5 are smaller than 7 and 8,10,9,8 are bigger than 7.
I am working on it for 2 weeks and I can't find a working solution />/>/>
There is the first try :
#include <stdio.h>
#include <stdbool.h>
int s_data[10]={2,3,4,6,5,7,8,10,9,8};
int main() {
int result,i,j,s_len ,tmp1,tmp;
bool GT_PREV,ST_NEXT;

I have the structure defined in the code below and need to insert a new string into the middle of the string array. I know there is a way to insert a new element with a vector. How to do this. I have tried several variations similar to uniqueList.word.insert(400,"disisdabomb"); but with no luck.
const int maxWordCount=1500;
struct wordCountList
{
string word[maxWordCount];
int count[maxWordCount];
};
wordCountList uniqueList;
