The first way is to declare a structure variable immediately after the structure definition, as follows: struct address { int house_number; char street_name[50]; int zip_code; char country[50]; } struct_var1, struct_var2; In the second way, you can declare the structure variable at a different location after structure definition. Here is structure declaration syntax: struct address { … Read more
In some programming contexts, you need to access multiple data types under a single name for easier data manipulation; for example you want to refer to address with multiple data like house number, street, zip code, country. C array is a derived data type allow you to define type of variables that can hold several … Read more
Arrays provide a mechanism to declare a derived data type which is a collection of homogenous elements. This means each element has same data type. However, it is sometimes required to create a collection of non- homogeneous elements in which elements can be of different type. Consider the automation of student records in University of … Read more
C does not have true multidimensional arrays. However, because of the generality of C’s type system; we can have arrays of arrays. This is what a 2D Array is. Consider the example of 2D Array discussed in last article. In this case, each row is one-dimensional array of 2 elements. Now, all these rows are … Read more
The array which is used to represent and store data in a tabular form is called as Two Dimensional Array. Such type of array specially used to represent data in a matrix form. To declare Two Dimensional Array in C, the general syntax is as follows: <data-type> <Array-name> [<rows>][<columns>]; The rows and columns, both must … Read more
The array which is used to represent and store data in a linear form is called as Single or One Dimensional Array. To declare One Dimensional Array in C, the general syntax is as follows: <data-type> <Array-name> [<Array-Size>]; The Array-Size must be an integer constant greater than zero and data-type can be any valid C … Read more
In C programming language, a derived data type which can store a collection of elements of the same data type is possible. Such a derived data type is called an Array. The data type of Array elements can be either primitive or user-defined. An array in C programing language can be defined as a name … Read more
Imagine that you have to store and later retrieve the unique ID of all of the registered voters in your city. Yes, you can create and name hundreds of thousands of distinct variable names to store the information. However, that would scatter hundreds of thousands of names all over memory. In addition, there is a … Read more
It is sometimes required to break from the inner loop of nested loops. In this a break statement can be used. However, the break statement will only exit from the nested inner loop in which it is encountered and control will be transferred to outer loop. In case we want to transfer control to some … Read more
Nesting loops means placing one loop inside the body of another loop. Any variant of loop can be nested inside any other variant of loop just like any variant of if-statement can be nested inside any other variant of if-statement. Also, logically there is not limit on the level of nesting. However, to make code … Read more
