In this article we will learn to implement a C program to swap the contents and indexes in an array. A C program is provided below for swapping the array element with the corresponding array index number. Given an array with size n and its contents are from 0 to n-1. Swap the index […]
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: Subscribe to our monthly newsletter. Get notified about […]
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 data. […]
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. Unions have the same syntax as that of a structure since both of them are similar. However, there is a major difference between […]
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. C supports […]
This article provides a comprehensive overview of pointers in C programming language along with useful example programs. A pointer is a derived data type in C. It is built from one of the fundamental data types available in C. Pointers contain memory addresses as their values. Since these memory addresses are the locations […]
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 C preprocessor provides several tools that are not present in other high-level languages. The programmer can […]
The storage classes in C specify the scope and lifetime of a variable in a C program. The scope (active) specifies in which parts of the program is the variable accessible and the lifetime (alive) specifies how long a variable is available in the memory so that the program will be able to access that […]
