Hello everyone! This article will specifically discuss the Arrow operator in the C programming language. C language offers a range of operators that can be used to handle and manipulate data records, and the Arrow operator is one of them.<\/p>\n

Okay, then let’s get started!<\/p>\n

\n

How does the Arrow operator function in the C programming language<\/a>?<\/h2>\n

In the C language, this operator allows programmers to retrieve the data elements of a Structure or a Union.<\/p>\n

The operator called arrow (->) is created by combining the minus (-) operator and the greater than (>) relational operator. In addition, it allows us to reach the elements of the struct or union indicated by a pointer variable.<\/p>\n

Now, let’s turn our attention to the syntax of the Arrow operator in the C programming language.<\/p>\n

\n

Arrow operator (->) syntax.<\/h2>\n

Take a look at the syntax below!<\/p>\n

(<\/span>pointer variable)<\/span>-><\/span>(<\/span>variable)<\/span> =<\/span> value;<\/span>\r\n<\/code><\/pre>\n
The operator is utilized alongside a pointer variable for storing the value at the specified location that the pointer\/object is pointing to.<\/p>\n
In the upcoming section, we will demonstrate the implementation of this operator using a few examples.<\/p>\n
\n
Instances showcasing the Arrow operator (->)<\/h2>\n
In the example below, we have defined a structure called ‘Movie_info’. Additionally, we have created a pointer object for the structure and allocated memory to it dynamically by utilizing the C malloc() function.<\/p>\n
The arrow operator is used to access the data member of a C structure.<\/p>\n
#<\/span>include<\/span> <stdio.h><\/span><\/span>\r\n \r\nstruct<\/span> Movie_info<\/span>\r\n{<\/span> \r\n    char<\/span> *<\/span>name;<\/span> \r\n    char<\/span> *<\/span>ACC;<\/span> \r\n}<\/span>;<\/span>\r\n \r\nint<\/span> main<\/span>(<\/span>)<\/span>\r\n{<\/span>\r\n     struct<\/span> Movie_info<\/span>*<\/span> M;<\/span>\r\n     M =<\/span> (<\/span>struct<\/span> Movie_info<\/span>*<\/span>)<\/span> \r\n        malloc<\/span>(<\/span>sizeof<\/span>(<\/span>struct<\/span> Movie_info<\/span>)<\/span>)<\/span>;<\/span> \r\n     \r\n     M-><\/span>name =<\/span> \"Python with Silicon Cloud\"<\/span>;<\/span>\r\n     M-><\/span>ACC=<\/span>\"A\"<\/span>;<\/span>\r\n \r\n     printf<\/span>(<\/span>\"Movie Information:\"<\/span>)<\/span>;<\/span>\r\n     printf<\/span>(<\/span>\"\\nName: %s\"<\/span>,<\/span> M-><\/span>name)<\/span>;<\/span>\r\n     printf<\/span>(<\/span>\"\\nACC: %s\"<\/span>,<\/span> M-><\/span>ACC)<\/span>;<\/span>\r\n     return<\/span> 0<\/span>;<\/span>\r\n}<\/span>\r\n<\/code><\/pre>\n
The data members’ values have been accessed using the arrow operator (->).<\/p>\n
Result:<\/p>\n
Movie Information:<\/span>\r\nName:<\/span> Python with Silicon Cloud\r\nACC:<\/span> A\r\n<\/code><\/pre>\n
Now, we will attempt to access the Union’s data members by using the arrow operator when working with data in C.<\/p>\n
#<\/span>include<\/span> <stdio.h><\/span><\/span>\r\n \r\nunion<\/span> Movie_info\r\n{<\/span> \r\n    int<\/span> id;<\/span>\r\n    float<\/span> net_val;<\/span>\r\n}<\/span>;<\/span>\r\n \r\nint<\/span> main<\/span>(<\/span>)<\/span>\r\n{<\/span>\r\n     union<\/span> Movie_info*<\/span> M;<\/span>\r\n     M =<\/span> (<\/span>union<\/span> Movie_info*<\/span>)<\/span> \r\n        malloc<\/span>(<\/span>sizeof<\/span>(<\/span>union<\/span> Movie_info)<\/span>)<\/span>;<\/span> \r\n     printf<\/span>(<\/span>\"Movie Information:\\n\"<\/span>)<\/span>;<\/span>\r\n     M-><\/span>id =<\/span> 01<\/span>;<\/span>\r\n     printf<\/span>(<\/span>\"\\n ID: %d\"<\/span>,<\/span> M-><\/span>id)<\/span>;<\/span>\r\n     M-><\/span>net_val =<\/span> 125.45<\/span>;<\/span>\r\n     printf<\/span>(<\/span>\"\\n NET VALUE: %.1f\"<\/span>,<\/span> M-><\/span>net_val)<\/span>;<\/span>\r\n     return<\/span> 0<\/span>;<\/span>\r\n}<\/span>\r\n<\/code><\/pre>\n
Similar to the Structure, we have formed a Union called ‘Movie_info’ and accessed the data values using the arrow operator as demonstrated earlier.<\/p>\n
We require only one option for you to paraphrase the following naturally:
\nResult:<\/p>\n
Movie Information:<\/span>\r\nID:<\/span> 1<\/span>\r\nNET VALUE:<\/span> 125.4<\/span>\r\n<\/code><\/pre>\n
\n
