All the members of the structure can be accessed at once,where as in an union only one member can be used at a time. Another important difference is in the size allocated to a structure and an union. for eg: struct example { int integer; float floating_numbers; } the size allocated here is sizeof(int)+sizeof(float); where as in an union union example { int integer; float floating_numbers; } size allocated is the size of the highest member. so size is=sizeof(float);

Difference between integer array and character array?
Arrays are basic structures wherein one or more elements exist "side by side" and are of the same "type". An "integer" array is an array whose elements are all of an integer type which has no fractional component. A "character" array is an array which contains nothing but character types. A "floating point" array contains elements that have both an integer and fractional portion. Simply put, they are arrays of particular types.
What is array What is difference between array and simple variable?
An array stores several values - for example, several numbers - using a single variable name. The programmer can access the individual values with a subscript, for example, myArray[0], myArray[5]. The subscript can also be a variable, for example, myArray[i], making it easy to write a loop that processes all the elements of an array, or some of them, one after another.

What is the difference between a numericial array and an associative array?
A numericial array is an array with keys made up of only integers. An associative array is an array with keys made up of anything that is not an integer. In some languages, it is possible to mix integer keys and non-integer keys into a mixed array.

What is the difference between an array element and a variable?
Array elements are all members of the same variable, indexed in a logical manner. variables are distinct objects which must be referred to distinctly. The main functional difference is that a program can iterate over an array without the programmer knowing the original size of the array or explicitly which member to access.
