“Array input output C program” is a C language program to input 10 integer numbers in a 10 element array. This program will show the entered elements on screen, too.
Array is a data structure which represents the collection of items of same type. For example, array of 10 integers may be defined as:
Where int is the data type, num is the name of array. Whereas 10 represents size of array. We can use an element with the help of index. For example to display first element , we will write
num represents first element of array, similarly 9 will represent the index of last element of array.
As in C language array index is zero based, therefore a 10 elements array will use indices from 0 to 9 for 10 elements. The first element of array has index 0 and the last item of array has index 9.
For input and output from array, we use “for loop” for ease of use and efficiency of program.
