In this article we will try to implement a C program to multiply consecutive numbers in an array. A C program is provided below to find the product of consecutive numbers in a given array. For example if the given array is: 1 2 5 4 1 2, then the output should be 1*2*1*2, […]
In this article we will learn to implement a C program to find number of duplicate elements in an array. A C program is provided below which reads a list of number and prints the number of duplicates in a given array. Note: This program only works if the numbers are repeated for 2 […]
In this article we will learn to implement a C program to print prime numbers up to n. A C program is provided below which accepts n as input from user and prints all the prime numbers up to n. The program is as follows: #include <stdio.h> #include <conio.h> #include <math.h> int main() { […]
In this article we will learn to implement a C program to print a pattern. A C program is provided below to print the following pattern when n is given as 3 1 2*3 4*5*6 2*3 1 Program to print the pattern is given below: #include <stdio.h> #include <conio.h> int main() { int n; […]
In this article we will learn to implement a C program to print a pattern of numbers. A C program is given below for printing a numbers pattern. Given starting number of a pattern and value of n, print the pattern as given below If starting value = 3 and n = 4 then […]
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: 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 data. […]
