Array is a type consisting of a contiguously allocated nonempty sequence of objects with a particularelement type. The number of those objects (the array size) never changes during the array lifetime. Syntax In thedeclaration grammarof an array declaration, thetype-specifiersequence designates theel...
If you don't specify the array size, an error occurs: Example string cars[];// Array size is not specified cars[0] ="Volvo"; cars[1] ="BMW"; cars[2]="Ford"; cars[3] ="Mazda"; cars[4] ="Tesla"; // error: array size missing in 'cars' ...
