Why does the above code print out hex numbers when I'm actually trying to print out the contents of the array. (Beginner/Just practicing)

What am I doing wrong that's causing this to occur?


To print out the contents of the table in a grid (as asked in one of the comments on Guarev Senghai's answer:

#include <iostream>
using namespace std;

int main() {

int troysArray[3][3] = {
    {3,2,7},
    {4,5,8},
    {1,9,2},
};

int i;
int j;

for (i = 0;i < 3;i++)
{
    for (j = 0;j < 3;j++)
    {
        cout << troysArray[i][j];  

        //uncomment the next line to have a spaces between the numbers.
        cout << " ";
    }
    cout << endl;
}

return 0;
}

How to Print Array with elements in Java?, Multidimensional array prints hexadecimal numbers instead of the contents of the array. Why? how to store hex value in char array in c two dimensional array in  Before we learn about the multidimensional array, make sure you know about Java array. A multidimensional array is an array of arrays. Each element of a multidimensional array is an array itself. For example, int[][] a = new int[3][4]; Here, we have created a multidimensional array named a. It is a 2-dimensional array, that can hold a maximum


The best overload of the std::ostream << operator for troysArray[i] is void* (exploiting pointer decay), and that outputs the address of the pointer.

If you want an element use troysArray[i][j] &c.

Multidimensional Arrays - MATLAB & Simulink, You cannot print array elements directly in Java, you need to use Arrays. toString(primes)); //Ok Output: Prime numbers : [I@5eb1404f Real prime numbers : [5, 7, 11, By the way, if you want to print byte array as Hex String then see this link. Arrays class provides a different method to print two dimensional array in Java,  In C programming, you can create an array of arrays. These arrays are known as multidimensional arrays. Here, x is a two-dimensional (2d) array. The array can hold 12 elements. You can think the array as a table with 3 rows and each row has 4 columns. Here, the array y can hold 24 elements. You can initialize a three-dimensional array in a


troysArray[i] and troysArray[j] are pointers to an array. If you want to print element at i and j, use

cout << troysArray[i][j] << endl;

Multi-Dimensional Arrays in C Programming: Definition & Example , Introduction An array is an ordered collection of elements. var arrObject = new Array("val1", 34, true); // string, number, boolean var You can print out an array; the JavaScript engine will automatically convert the array into a string representation: You want to create a multidimensional array (an array of arrays​). troysArray is an array of arrays of int. Thus, troysArray[i] is an array of int, and so is troysArray[j]. There is no overload of operator << for array of int. However, there is one for void*. When you pass an array as an argument, what actually gets passed is a pointer to the array's first element.


troysArray is an array of arrays of int. Thus, troysArray[i] is an array of int, and so is troysArray[j].

There is no overload of operator << for array of int. However, there is one for void*.

When you pass an array as an argument, what actually gets passed is a pointer to the array's first element. (In your case, those are &troysArray[i][0] and &troysArray[j][0], both of type int*.)

An int* can be implicitly converted to void*, so the operator << for void* can be used.

This overload outputs the value of the pointer in hexadecimal form.

In order to print the ints you need to print the elements j of each array troysArray[i]:

cout << troysArray[i][j] << endl;

To print it more "matrix-like", with each row on its own line:

for (int i = 0; i < 3; i++)
{
    for (int j = 0; j < 3; j++)
    {
        cout << troysArray[i][j] << ' ';
    }
    cout << endl;
}

Three-Dimensional Arrays in C, The two dimensional (2D) array in C programming is also known as matrix. by user in a 2d array and how to display the elements of a two dimensional array. of first element of the first row (if we consider the above diagram number 1). be in hex for which we use %p instead of %d, as mentioned in the comments. This is​  ARG 0-5 are the values i need and these are in hexadecimal format; the rest of the stuff is not important. I need these values converted to decimal numbers and written to a spreadsheet. I've attached the original VI and a modified VI where we attempted to convert HEX to decimal.


5. Working with Arrays and Loops, Here, is a c program, which is using to initialize array elements using hexadecimal values and printing the values in hexadecimal and decimal  The number inside the brackets of an array definition is the _____, but the number inside an array's bracket is an assignment statement, or any other statement that works with the contents of the array, is the_____.


Two dimensional (2D) arrays in C programming with example, Sum the odd and even numbers, respectively, from 1 to a given upperbound. Print the results cout << "The sum of odd numbers is " << sumOdd << endl; cout For example, character '0' is 48 (decimal) or 30H (hexadecimal); character 'A' is 65 Instead, You could use a single variable, called an array, with 30 elements. In this tutorial, you will learn to work with arrays. You will learn to declare, initialize and access array elements of an array with the help of examples. An array is a variable that can store multiple values. For example, if you want to store 100 integers, you can create an array for it. Here, we declared an array, mark, of floating-point type.


How to initialize array elements with hexadecimal values in C , Sum the odd and even numbers, respectively, from 1 to a given upperbound. * Also compute the C programs use function printf() of library stdio to print output to the console. n", aStr); //The string is Hello. printf("The int (in hex) is %x.\n", anInt); Instead, You could use a single variable, called an array, with 30 elements. Two-dimensional arrays. In many applications, a natural way to organize information is to use a table of numbers organized in a rectangle and to refer to rows and columns in the table. The mathematical abstraction corresponding to such tables is a matrix; the corresponding Java construct is a two-dimensional array. Two-dimensional arrays in Java.
