Program for if else

#include <iostream.h>

int main() {

int n;

cout<<"Enter the number";

cout<<"is even number ";

return 0;

}

OUTPUT

int main()

{

char op;

float num1, num2;

cout << "Enter operator either + or - or * or /: ";

cin >> op;

cout << "Enter two operands: ";

cin >> num1 >> num2;

switch(op)

{

case '*':

cout <<"The Mul of a & b is: "<< num1*num2;

break;

case '/':

cout <<"The Div of a & b is: "<< num1/num2;

break;

default:

// If the operator is other than +, -, * or /, error message is shown

cout << "Error! operator is not correct";

break;
