Aryan Soni 7 years, 10 months ago

, a wave is an oscillation accompanied by a transfer of energy. Frequency refers to the addition of time. Wave motion transfers energy from one point to another, which displace particles of the transmission medium–that is, with little or no associated mass transport. Waves consist, instead, of oscillations or vibrations

BASIS FOR COMPARISON	ONE-DIMENSIONAL	TWO-DIMENSIONAL
Basic	Store single list of elements of similar data type.	Store 'list of lists' or 'array of arrays' or 'array of one dimensional arrays'.
Declaration	/declaration in C++ type variable_name[ size ];/ /declaration in Java type variable_name [ ]; variable_name = new type[size]; /	/declaration in C++ type variable_name[size1][size2]; / /declaration in Java type variable_name= new int[size1][size2]; /
Alternative Declaration	/* In Java int [ ] a= new int [10]; */	/* In Java int [ ] [ ] a= new int [10][20]; */
Total Size in Bytes	Total Bytes =sizeof(datatype of array variable)* size of array.	Total Bytes= sizeof(datatype of array variable)* size of first index*size of second index.
Receiving parameter	It can be received in a pointer, sized array or an unsized array.	Parameter receiving it should define the rightmost dimension of an array.
Dimensions	One dimensional.	Two dimensional.
