In this article we will learn to implement a C program to print a pattern. The following C program prints the below pattern for n = 4. 1*2*3*4*17*18*19*20 5*6*7*14*15*16 8*9*12*13 10*11 The program is as follows: #include <stdio.h> #include <conio.h> int main() { int n = 4; int lstart = 1; int rstart = […]
In this article we will learn to implement sorting an array in Java. A Java program is provided below to read a list of numbers and sort them. I have used exchange sort to sort the array in ascending order. The program is as follows: import java.util.*; class Driver { static void printArray(int […]
In this post we are going to look at some very basic and frequently asked array programs in Java interviews . Different programs are written as separate functions in the class ArrayClass. These programs are restricted to integers. Following programs are available: Reading elements into an array Printing elements in an array Printing the sum of […]
This article provides a comprehensive overview of files in C programming language along with relevant examples. So far we have been using scanf and printf functions for reading and writing data to the console. This is fine as long as the data is less. However, many real world problems involve large amounts of […]
In this article you will learn about Unions in C language. First you will learn what is a Union, its syntax and then an example program demonstrating unions in C language. However, there is a major difference between them in terms of memory allocation. Like structure, a union can be […]
This article provides a comprehensive overview of structures in C programming language along with example programs. We know that arrays can be used to represent a collection of elements of the same data type like int, float etc. They cannot be used to hold a collection of different types of elements. […]
This article provides a comprehensive overview of pointers in C programming language along with useful example programs. Since these memory addresses are the locations in the computer memory where program instructions and data are stored, pointers can be used to access and manipulate data stored in the memory. Advantages of […]
This article provides a comprehensive overview of preprocessor directives in C programming language along with relevant examples. C provides many features like structures, unions and pointers. Another unique feature of the C language is the preprocessor. The programmer can use these tools to make his program easy to read, easy to modify, […]
The storage classes in C specify the scope and lifetime of a variable in a C program. Learn more about C programming language basics. The storage classes’ auto, register, and static can be applied to local variables and the storage classes’ extern, and static can be applied to global variables. auto […]
In this article we will learn about types of variables in C language. We will start with what is variable and then learn about types of variables like local variables and global variables. Learn more about C basics. A variable is a memory location inside memory which is referred using a name. […]
