C++ LANGUAGE INITIALIZING ARRAYS

Initializing Arrays 


You can initialize C++ array elements either one by 
one or using a single statement as follows: 

double balance[5] = {1000.0, 2.0, 3.4, 17.0, 50.0}; 

The number of values between braces { } cannot be larger than 
the number of elements that we declare for the array between 
square brackets [ ]. Following is an example to assign a single element of the array: 

If you omit the size of the array, an array just big enough 
to hold the initialization is created. Therefore, if you write: 

double balance[] = {1000.0, 2.0, 3.4, 17.0, 50.0}; 
 

You will create exactly the same array as you 
did in the previous example. 

balance[4] = 50.0; 
The above statement assigns element number 5th in the array 
a value of 50.0. Array with 4th index will be 5th, i.e., 
last element because all arrays have 0 as the index of their 
first element which is also called base index. Following is 
the pictorial representation of the same array we discussed above:
