To work with multiple AND conditions in MySQL, following is the syntax −select *from yourTableName where yourColumnName1=yourValue1 and yourColumnName2=yourValue2 and yourColumnName3=yourValue3;Let us first create a table −mysql> create table DemoTable ( StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, StudentName varchar(20), StudentAge int, StudentCountryName varchar(40) ); Query OK, 0 rows affected (0.59 sec)Insert some records in the table using insert command −mysql> insert into DemoTable(StudentName, StudentAge, StudentCountryName) values('John', 23, 'US'); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable(StudentName, StudentAge, StudentCountryName) values('Carol', 21, 'UK'); Query OK, 1 row affected (0.15 sec) mysql> insert ...

A pointer is used to store the address of the variables. To declare pointer variables in C/C++, an asterisk (*) used before its name.Declaration*pointer_nameIn CExample Live Demo#include int main() { // A normal integer variable int a = 7; // A pointer variable that holds address of a. int *p = &a; // Value stored is value of variable "a" printf("Value of Variable : %d", *p); //it will print the address of the variable "a" printf("Address of Variable : %p", p); // reassign the value. *p = 6; printf("Value ...

When a program or function statement is executed, the current values of formal parameters are saved (on the stack) and within the scope of the statement, they are bound to the values of the actual arguments made in the call. When the statement is exited, the original values of those formal arguments are restored. This protocol is fully recursive. If within the body of a statement, something is done that causes the formal parameters to be bound again, to new values, the lambda-binding scheme guarantees that this will all happen in an orderly manner.there is only one binding for x: ...

Here we will see how to generate lexicographically next permutation of a string in C++. The lexicographically next permutation is basically the greater permutation. For example, the next of “ACB” will be “BAC”. In some cases, the lexicographically next permutation is not present, like “BBB” or “DCBA” etc.In C++ we can do it by using a library function called next_permutation(). This is present in the algorithm header file.Example#include #include using namespace std; main() { string s = "DBAC"; for(int i = 0; i
Here we shall discuss a C++ program to find the Longest Subsequence Common to All Sequences in a Set of Sequences.AlgorithmsBegin Take the array of strings as input. function matchedPrefixtill(): find the matched prefix between string s1 and s2 : n1 = store length of string s1. n2 = store length of string s2. for i = 0, j = 0 to i
Token Bus (IEEE 802.4) is a standard for implementing token ring over the virtual ring in LANs. The physical media has a bus or a tree topology and uses coaxial cables. A virtual ring is created with the nodes/stations and the token is passed from one node to the next in a sequence along this virtual ring. Each node knows the address of its preceding station and its succeeding station. A station can only transmit data when it has the token. The working principle of the token bus is similar to Token Ring.Token Passing Mechanism in Token BusA token is ... Read More
JavaScript TagsThe html script tag wants the browser to get a script between them. We can expect the scripts to be in the following places. 1.The script can be placed in html's head tag 2.Within Html's body tag. 3.As an external file. Most importantly client side scripts such as JavaScript are placed in script tags.demonstration code Live Demo This example writes "JavaScript is not java" into an HTML element with id="script" document.getElementById("imp").innerHTML = "JavaScript is not java"; OutputThis example writes "JavaScript is not java" into an HTML element with id="script" JavaScript is not javaExplanationEvery JavaScript code should be in ...
