A pointer is a variable which contains the address of the variable specified. For example: int x = 100; int *data; data = &x; This variable data contains the address of the block in the memory which contains the value 100. * specifies that this is the pointer variable. & gives the address. that is the what I am doing here assigning the address of the integer variable x to the pointer variable data....

Array in C an array is a collection of a variable of a fixed number of the same data type in a sequential memory. an array can be declared in various ways. one of them is given below int x[] = {200,300,522,655}; char y[] = {'x','s','r'}; int n[10],j; // first declaring the array // then assigning the value. for ( j = 0; j < 10; j++ ) { n[ j ] = j + 100; } indexing in C array starts from the 0....

Palindrome string: A string or word which are same from the start and end means word or program which look like same as original and reversed. To do that we have to first reverse the string. Check out our post on the String reverse in C/C++. To write the program of the Palindrome steps used are. Get the input from the user. convert the string to the Lower case to avoid any case sensitivity....

String In C language string is an Array of the Char variable. to write a program of the string reverse we have to break this program into steps as always. Take input from the user. Reverse the string using the for loop print the final answer to the user. First of All, create a schema for the program. #include <stdio.h> #include <string.h> int main(int argc, char const *argv[]) { return 0; } Now write some code for the Taking input from the user....

Introduction In this blog post we will learn about the foreach loop in javascript if you are new to javascript please see this. Folks who haven’t used since long time here is the refresher. What is For Each Loop: this is the loop which automatically iterates through all the elements of an array, it helps in the working with the dynamic array. Let’s start working.

After splitting this email address by “@”, there will be two strings “example”, “gmail.com”. Use case of string splitting contains, tokenizing things in compilers, extracting relevant data with Web crawlers etc....
