Explain declaration, initialization of One dimensional and Two dimensional arrays.
Solution
==> One Dimensional Array---
Declaration::
Syntax: data_type array_name[array_size];
where, data_type can be int, float or char.
array_name is the name of the array.
array_size indicates number of elements in the array.
For ex: int age[5];
Initialization::
Syntax: data_type array_name[array_size]={v1,v2,v3};
where, v1, v2, v3 are the values
For ex: int age[5]={2,4,34,25,18};
==> Two Dimensional Array----
Declaration::
Syntax: data_type array_name[array_size][array_size];
where, first index shows the row number of the element and
second index shows the coulmn number of the element
Initialisation::
Syntax: data_type array_name[array_size][array_size]={V1,V2,V3,.....Vn};
where, V1, V2, V3,......,Vn are the values
For ex: int matrix[2][3]={2,4,56,3,6};
