C++ Program to Implement a Simple Calculator
Below is the C++ program to make a simple calculator using switch and break statements:
C++
// C++ program to create calculator using// switch statement#include <iostream>using namespace std;// Driver codeint main(){ char op; float num1, num2; // It allows user to enter operator // i.e. +, -, *, / cin >> op; // It allow user to enter the operands cin >> num1 >> num2; // Switch statement begins switch (op) { // If user enter + case '+': cout << num1 + num2; break; // If user enter - case '-': cout << num1 - num2; break; // If user enter * case '*': cout << num1 * num2; break; // If user enter / case '/': cout << num1 / num2; break; // If the operator is other than +, -, * or /, // error message will display default: cout << "Error! operator is not correct"; } // switch statement ends return 0;} |
