Swap means exchange the value of two variable. There is four different method. Using Temporary Variable Without Using Temporary Variable Using Bitwise Operator Using Multiplication And Division Using Temporary Variable #include <iostream> using namespace std; int main() { int a = 31, b = 12, temp; cout << "Before swapping " << endl; cout << "a = " << a << ", b = " << b << endl; temp = a; a = b; b = temp; cout << "\nAfter swapping" << endl; cout << "a = " << a << ", b = " << b << endl;…

In this program,it will take two integers (divisor and dividend) and find the quotient and remainder. To compute quotient and remainder, both divisor and dividend should be integers. #include <iostream> using namespace std; int main() { int divisor, dividend, quotient, remainder; cout << "Enter dividend: "; cin >> dividend; cout << "Enter divisor: "; cin >> divisor; quotient = dividend / divisor; remainder = dividend % divisor; cout << "Quotient = " << quotient << endl; cout << "Remainder = " << remainder; return 0; } OutPut Enter dividend: 17 Enter divisor: 4 Quotient = 4 Remainder = 1

In this program, two integer values taken from user and then sum of this values are stored in another variavle and then print it. #include <iostream> using namespace std; int main() { int firstNo, secondNo, sumOfTwoNo; cout << "Enter two integer values: "; cin >> firstNo >> secondNo; sumOfTwoNo = firstNo + secondNo; cout << firstNo << " + " << secondNo << " = " << sumOfTwoNo; return 0; } OutPut Enter two integer values: 4 5 4 + 5 = 9

cin>> is used to take value from the user. cout<< is used to print value. #include <iostream> using namespace std; int main() { int no; cout << "Enter an integer value: "; cin >> no; cout << "You entered " << no; return 0; } OutPut Enter an integer value: 23 You entered 23

Learning C++ programming can be simplified into: Writing your program in a text-editor and saving it with correct extension(.CPP, .C, .CP) Compiling your program using a compiler or online IDE The “Hello World!” program is the first step towards learning any programming language and also one of the simplest program you will learn. All you have to do is display the message “Hello World!” on the screen. Then let’s get started. Here, #include<iostream> is header file that contains standard input output library functions. A namespace is a form of scope in C++ that holds its own definitions for variables, functions,..…
