Write a c program to find average of n numbers using array

In C99 there is an alternate mechanism, that allows you to initialize specific elements, not necessarily at the beginning. The traditional method for handling character strings is to use an array of characters.

Another way of looking at this is that C stores two dimensional arrays by rows, with all elements of a row being stored together as a single unit.

For a multi-dimensional array, all dimensions except the first must be provided in a functions formal parameter list.

Program in C to find the mean of n numbers using array

When an entire array is passed to a function, the size of the array is usually passed as an additional argument. The cstring library contains a number of functions for dealing with traditional arrays of characters. Multidimensional arrays - see below.

What is the output of the following program: By analogy, multi-dimensional arrays do not require the first dimension to be given if the array is to be completely initialized.

The first dimension is optional, and will be ignored by the compiler. In C99, dimensions must still be positive integers, but variables can be used, so long as the variable has a positive value at the time the array is declared.

This is because the index in C is actually an offset from the beginning of the array. An array may be partially initialized, by providing fewer data items than the size of the array. Because arrays are passed by reference, there is generally no need for a function to "return" an array.

When subsets of braces are used, the last item within braces is not followed by a comma, but the subsets are themselves separated by commas.

Knowing this can sometimes lead to more efficient programs. So if nums was declared as a one-dimensional array of ints, then passing nums[ i ] to a function would behave the exact way as passing any other int - Either pass-by-value or pass-by-reference, depending on how the function is written.

Note the use of arrays and functions in the following sample program. When an entire array is passed to a function, however, it is always passed by reference.

Uninitialized arrays must have the dimensions of their rows, columns, etc. As with traditional methods, all uninitialized values are set to zero. This is cheating, but it happens to work because of the way that the rows of a multidimensional array are stored.

The array does NOT change sizes later if the variable used to declare it changes. If the size of the array is not given, then the largest initialized position determines the size of the array. Why is it possible to pass a row this way, but not a column?

Array indices start at zero in C, and go to one less than the size of the array. One dimensional arrays do not require the dimension to be given if the array is to be completely initialized.

The compiler will automatically size the array to fit the initialized data. For example, a five element array will have indices zero through four.

Note that in the calculation of max4, we have passed a two dimensional array containing two rows of three elements as if it were a single dimensional array of six elements. The reasons for this and the incentive to do this relate to memory-management issues that are beyond the scope of these notes.

A partially qualified multi-dimensional array may be passed to a function, and will be treated as an array of lower dimension.

Note the use of commas in the examples below. All dimensions after the first must be given in any case.

I made what I could but the program doesn't work it took me hours trying to figure it out.
