I have this problem when I write this string array of months. I've tried making it a const, static, even const char * but nothing seems to work. I was wondering if I had to make a constructor for it but I'm not sure how to do that.
const int NUMBER_OF_MONTHS = 12;
class Date
{
public:
[Code]....
This is the error i get: error C2536: 'Date::Date::n_month' : cannot specify explicit initializer for arrays
called object 'fptr_in' is not a function or function pointer
called object 'fptr_out' is not a function or function pointer
what can i do for the errors?(i mustn't use loop and arrays for the code)
Code:
#include <stdio.h>
void sum_of_2nd_and_3nd( FILE* fptr_in, FILE* fptr_out);
int main()
return 0;
}
void sum_of_2nd_and_3nd( FILE* fptr_in, FILE* fptr_out){
}

I have a crash on a application the customer machine i couldn't reproduce it yet on my machine... all i have is the error message
The Instruction 0x0070478b referencing to the memory 0x00000000 could not be written.
And that's all i have how do i track that instruction on my program from that address? is it possible?
I'm new in programming, and trying to write a code in C. The requirement is following - to write a text, and to find frequency of 1 chosen character in it. The main thing is that program should check user input (for example, I want to check if user entered "char" --> then correct, or if entered "int" --> not correct). But the program still doesn't check. So I have:
Code:
#include <stdio.h>
int main(){
char c[1000], ch;
char i, count=0;
printf("Enter a text: ");
gets(c);
[Code] ....
Am I on my right way using if/else?
Write a function that takes an array and returns true if all the elements in the array are positive, otherwise, it returns false.

im trying to write an array of struct to a binary the array of struct is filled with data from a text file .
the program gives no errors or warnings but does not write anything at all to the binary file here is the main
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
struct matches
{
char teamA[20] ;
char teamB[20];
int scoreA ;
int scoreB;

I'm not sure if I should do this with malloc or a char array. What I need to do is create 4 methods to read and 4 to write to memory like this (and it has to be fast):
Code:
char GetByte(char* memory, int offset);
uint16 GetInt16(char* memory, int offset);
uint32 GetInt32(char* memory, int offset);
char[] GetString(char* memory, int offset);
So basically memory is the malloced memory and the offset is the position I want to read at.
I'm not sure if there's already a way to do this and maybe I'm overlooking something.
Create a program that will ask the user to input 10 integers of an array the program must write the index of the greatest element of the array
target output
input the integers
the greatest element is 5 and the index is 7
write a program that ask his or her name and store it in a character array
View 1 Replies View RelatedI am trying to write a program that adds numbers to an array. The array capacity starts out at 2, then doubles whenever the size reaches capacity. The program works perfectly fine when the array needs to be expanded. So I have narrowed down the issues into this one function (_dynArrSetCapacity)
Creates original array
DynArr* createDynArr(int cap) {
assert(cap > 0);
DynArr *r = (DynArr *)malloc(sizeof( DynArr));
assert(r != 0);
initDynArr(r,cap);
[Code]...
If i do createDynArr(10) for instance in the main, the program works perfectly, as it never gets expanded
I decided I wanted to make a proper programming language with a virtual machine and bytecode. I used this tutorial: [URL] .....
As a starting point for my project. So far I have modified it to allow for 32-bit addressing so that I can theoretically use 4GB in my programs. Now the problem I'm having is creating the memory.

I'm doing a Text-based RPG game and it will include some checkpoints, on those checkpoints the game will save the progress, so I need to write all my variables to a text file and then read them all when the player loads the game.
Some of my variables, like enemyNames, dont have any determined size, they're like this: "int enemyNames[];"
So how do I write an array to a text file without determining a size?
And how do I read them when the player loads the game?
In my application there is a structure that holds 200 parameters for 200 tests. These structure is converted to byte array . I want to write this byte array to a file in save button and when I click open button, this file must open and write these bytes to corresponding text boxes. How it possible.?

i need to write a function with an array parameter and an int parameter.
that array has to be filled with first 10 prime numbers that are exact or higher than the int parameter...and then i need an average value of those 10 prime numbers...
The problem is im not really sure how i should do the part to fill the array with prime numbers that are higher than that int??
Code:
int avgprimearray (int higharray[], int somenumber){
}
Write a program which stores 10 decimal numbers in an array. For these numbers accept input from the users. Once the array is populated do the followings:
Display each elements of the array
Display the sum of all the elements of array
write a function accepts two arguments, an array of integers and a number indicating the number of elements in the array. the function should recursively calculate the sum of all the numbers in the array. Demonatrate the use of the functions in a program that asks the users to enter an array of numbers and prints it sum
i had done this but it wont work
#include <iostream>
#include <conio.h>
#include <iomanip>

I'm trying to get correct answers from my exam to study for a midterm:
Write a function that returns the maximum value of an array of doubles.
Declaration:
double maximum(array[],int a_size);
So far I've done:
double maximum(array[], int a_size) {
double maxVal;
maxVal = array[0];
for(int i=1; i < size; i++) {
if(array[i] > max
maxVal=array[i]
}
return maxVal;
}
I just need any corrections.
Second, I need to write a function definition that merges two vectors containing integers, alternating elements from both vectors.
Prototype:
vector<int> merge(const vector<int> a, const vector<int> b);
This is my definition so far:
vector<int>merge(const vector<int> a, const vector<int> b){
vector<int> merged;
for(int i=0; i<a.size+b.size; i++) {
if(flag == true)
merged.push_back(a);
flag = false;
else
merged.push_back(b)
flag = true;}
I think I'm lost in the second part...
I have an assignment which requires me to do the following:
Required to write a function that finds an integer in an array and returns its corresponding index. The function must be called findNumber. It must have FOUR parameters:
- The first parameter is the array to be searched
- The second parameter is the integer to be found within the array
- The third parameter is the size of the array
- The fourth parameter is an integer that indicates whether the array is sorted. A value of 1 means the array is sorted; a value of zero means the array is not sorted.
Since a function can only return one value(To return the position of a required integer in an array in this instance) I have tried to make use of pointers to try and return a value stating whether the array is sorted or not.This is my code : (It compiles perfectly but it does not produce any outputs)
Code:
#include <stdio.h>
#define SIZE 10
size_t findNumber(int *sort, const int array[],int key,size_t size);
int main(void){
int a[SIZE];
size_t x;

I've been getting this expression of "subscript being out of range" for my program but i'm not sure how exactly. I'm fiddling around with code, i'm trying to make a two dimensional array of random numbers, here is my code, it compiles just fine:
Code:
#include <iostream>
#include <array>
#include <random>
#include <cstdlib>
#include <iomanip>

My program has two errors, they are intellisense:An array may not have elements of this type. and missing subscript
Code:
#define ROWS 20

int i,i2;
for( i = 0; i <= ROWS; i++)
[Code] .....It has both of these errors for both of my arrays.
this program is just to give the size and value of the array by the user.
Code:
#include <stdio.h>
main( ) {
int size ;
scanf ( "%d", &size ) ;
int arr[size] ;
for ( i = 1 ; i <= size ; i++ ) {
scanf ( "%d", arr[i] ) ;
printf ( "%d", arr[i] ) ;
}
error : Code:
