array declaration c++

string cars[4] = {"Volvo", "BMW", "Ford", "Mazda"};

int foo[5] = {0};

// Array declaration by specifying size and initializing 
// elements 
int arr[6] = { 10, 20, 30, 40 } 
  
// Compiler creates an array of size 6, initializes first 
// 4 elements as specified by user and rest two elements as 0. 
// above is same as  "int arr[] = {10, 20, 30, 40, 0, 0}" 

int foo [5];

// datatype var_name[howmuch value you need to store] = {values, values}
int a[5] = {1, 2 3, 4, 5};
