Learn to create and populate a C++ array.

In this tutorial we will look at the C++ arrays.

Let's begin by creating a static array. Static arrays are the ones that are not resizable.

 Code Snippet 1


#include <stdio.h>

//Allocate a static array of 8 slots
//Array of Type int

  int main() {

  int myArray[8]; 


  myArray[0]=1892874;
  myArray[1]=239583;
  myArray[2]=2453;
  myArray[3]=256747;
  myArray[4]=6834838;
  myArray[5]=85954836;
  myArray[6]=85737;
  myArray[7]=7403853;

  }


Dynamic arrays are declared using pointers.

 Code Snippet 2

#include <stdio.h>

//Allocate a dynamic resizable array of 8 slots
//Array of Type int

  int main() {

  //Declare array using a pointer to memory
  int *myArray; 
   
  myArray = new int[8]; 

  myArray[0]=1892874;
  myArray[1]=239583;
  myArray[2]=2453;
  myArray[3]=256747;
  myArray[4]=6834838;
  myArray[5]=85954836;
  myArray[6]=85737;
  myArray[7]=7403853;

  //resize it

  myArray = new int[9];

  //populate

  for(int i=0; i< sizeof(myArray); i++) {
myArray[i] = i * 965 -34;
  }

  }
