C Language Initialization Initializing structures and arrays of structures
Example
Structures and arrays of structures can be initialized by a series of values enclosed in braces, one value per member of the structure.
struct Date
{
int year;
int month;
int day;
};
struct Date us_independence_day = { 1776, 7, 4 };
struct Date uk_battles[] =
{
{ 1066, 10, 14 }, // Battle of Hastings
{ 1815, 6, 18 }, // Battle of Waterloo
{ 1805, 10, 21 }, // Battle of Trafalgar
};
Note that the array initialization could be written without the interior braces, and in times past (before 1990, say) often would have been written without them:
struct Date uk_battles[] =
{
1066, 10, 14, // Battle of Hastings
1815, 6, 18, // Battle of Waterloo
1805, 10, 21, // Battle of Trafalgar
};
Although this works, it is not good modern style — you should not attempt to use this notation in new code and should fix the compiler warnings it usually yields.
