There are two ways you can declare and initialize an array in Java. The first is with the new keyword, where you have to initialize the values one by one. The second is by putting the values in curly braces.

You can declare an array of any data type (i.e. int, float, double, char) in C. The following ways can be used to declare and initialize an array in C. 

 

Array Declaration by Specifying the Size

Arrays can be declared by specifying the size or the number of array elements. The size of the array specifies the maximum number of elements that the array can hold. In the latest version of C, you can either declare an array by simply specifying the size at the time of the declaration or you can provide a user-specified size. The following syntax can be used to declare an array simply by specifying its size.

 

 // declare an array by specifying size in [].

int my_array1[20];

char my_array2[5];

// declare an array by specifying user defined size.

int size = 20;

int my_array3[size];
