To initialize an array variable by using an array literalEither in the New clause, or when you assign the array value, supply the element values inside braces ( {} ). The following example shows several ways to declare, create, and initialize a variable to contain an array that has elements of type Char .
int num[5] = {1, 1, 1, 1, 1}; This will initialize the num array with value 1 at all index. The array will be initialized to 0 in case we provide empty initializer list or just specify 0 in the initializer list. Designated Initializer: This initializer is used when we want to initialize a range with the same value.
I'm using C++ to create a tile map for a game. My problem is, I want to populate a multidimensional array of ints in the Map constructor, but it's not working properly. Here's my code in "Map.h" (irrelevant code has been removed).
class Map {
private:
int mapArray[15][20];
};
And my code from Map.cpp
Map::Map()
{
mapArray = {
{ 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19 },
{ 20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39 },
{ 40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59 },
{ 60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79 },
{ 80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99 },
{ 100,101,102,103,104,105,106,107,108,109,110,111,112,113,114,115,116,117,118,119 },
{ 120,121,122,123,124,125,126,127,128,129,130,131,132,133,134,135,136,137,138,139 },
{ 140,141,142,143,144,145,146,147,148,149,150,151,152,153,154,155,156,157,158,159 },
{ 160,161,162,163,164,165,166,167,168,169,170,171,172,173,174,175,176,177,178,179 },
{ 180,181,182,183,184,185,186,187,188,189,190,191,192,193,194,195,196,197,198,199 },
{ 200,201,202,203,204,205,206,207,208,209,210,211,212,213,214,215,216,217,218,219 },
{ 220,221,222,223,224,225,226,227,228,229,230,231,232,233,234,235,236,237,238,239 },
{ 240,241,242,243,244,245,246,247,248,249,250,251,252,253,254,255,256,257,258,259 },
{ 260,261,262,263,264,265,266,267,268,269,270,271,272,273,274,275,276,277,278,279 },
{ 280,281,282,283,284,285,286,287,288,289,290,291,292,293,294,295,296,297,298,299 }
};
}
PS. creating the mapArray locally, within a member function using int mapArray[15][20] and populating it then is working fine, I just can't seem to get it to populate in the constructor, with a member variable.
PPS. Very rusty with C++, please be gentle.
