'a array' is substandard, if you use it, you might be frowned upon.
An array is an aggregate of the same type. A structure is an aggregate of different types.
structure is a collection of dissimilar datatypes whereas array is collection of similar datatypes.....
3 differences.................. 1. length wise.... 2.initialization 3. null terminated length of char array is differ from string........ initialization of string is differ from char....... and string is null terminated...........
A single memory position variable can store only one value of its type. An array can store n number of values, where n is the size of the array.
A one dimensional array is a scalar value repeated one or more times.A two dimensional array is an array of one dimensional arrays.A three dimensional array is an array of two dimensional arrays, and so forth.The one dimensional array is like a list of things, where the two dimensional array is like an array of things. (Think one row of a spreadsheet versus the whole spreadsheet.)[addendum]Every level of array depth is also a level of pointer depth. For example: A 3 dimensional int array is an int***. So a one dimensional int array is an int*, and a two dimensional int array is an int**. This is only important if you are doing pointer work, but it can become very important.
They are physically different. LGA (Land Grid Array) uses surface-mountedconnectors, PGA (Pin Grid Array) uses pin connectors, and SECC (Single Edge Contact Cartridge) uses a slot connector.
A single dimensional array is an array of items. A two-dimensional array is an array of arrays of items.
An irregular dimensional array is a special type of multi-dimensional array.First we must understand that a multi-dimensional array is just an array of arrays. Each element in the array is, itself, an array of elements.A regular multi-dimensional array will be an array of size n, with each element containing a separate array of size m. That is, each sub-array has the same size.An irregular multi-dimensional array will be a multi-dimensional array in which each sub-array does not contain the same number of elements.Regular array:array[0] = new array{0, 1, 2}array[1] = new array{3, 4, 5}array[2] = new array{6, 7, 8}array[3] = new array{9, 10, 11}This regular array is an array of size 4 in which each sub-array is of size 3.Irregular array:array[0] = new array{0, 1, 2}array[1] = new array{3, 4}array[2] = new array{5, 6, 7}array[3] = new array{8, 9, 10, 11}This irregular array is an array of size 4 in which the size of each sub-array is not the same.
ordanry variable store one value at a time. arrays are used for storing more than one value at a time in a single variable name ordanry variable doesnt have subscript. array must have subscript syntax for ord. variable Datatype v1,v2...... syntax for array variable Datatype v1[n1],v2[n2].....
Option 1) Use a temporary variable: int x = array[i]; array[i] = array[i+1]; array[i+1] = x; Option 2) Use bit operators: array[i] ^= array[i+1] ^= array[i];
An array literal is a comma-separated list of the elements of an array. An array literal can be used for initializing the elements of an array.
[]temp = array[1] array[2]=array[1] array[1]=[]temp
