Editor to share with you whether the elements in the array can be different data types, I believe most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article. Let's learn about it!

No; the data type of each element in the array is the same. An array is a commonly used data structure, which is a collection of ordered data; each element in the array has the same data type, and the elements in the array can be uniquely determined by a unified array name and subscript.

No; the data type of each element in the array is the same.

The concept and definition of array

We know that if you want to put data into memory, you must first allocate memory space. If you put in four integers, you have to allocate four memory spaces of type int:

Int a [4]

In this way, four int-type memory spaces are allocated in memory, with a total of 4 × 4 bytes, and a name is given to them.

We call such a set of data Array, each data it contains is called array element (Element), and the number of data it contains is called array length (Length), such as int a [4]; we define an integer array of length 4, whose name is a.

Each element in the array has an ordinal, which starts at 0 instead of the familiar 1, called Index. When using array elements, you can simply specify the subscript in the form:

ArrayName [index]

ArrayName is the array name and index is the subscript. For example, a [0] represents the 0th element and a [3] represents the third element.

Next we put the four integers in the first line into the array:

A [0] = 20 [1] = 345 [2] = 700 [3] = 22

Here 0, 1, 2, 3 are array subscripts, and a [0], a [1], a [2], a [3] are array elements.

In the process of learning, we often use a loop structure to put data into an array (that is, assign values to the array elements one by one), and then use the loop structure to output (that is, read the values of the array elements in turn). Let's demonstrate how to put the ten numbers 1-10 into an array:

# include int main () {int nums [10]; int I; / put 1x10 into the array for (iTuno; I)
