Calculator
This is the C++ calculator example program. It is basic calculator that can sum, subtract, multiply, and divide two numbers. #include <cstdlib>
#include <iostream>
double sum(double a,double b);
void menu();
double subtract(double a,double b);
double multiply(double a,double b);
double divide(double a,double b);
using namespace std;
int main(int argc, char *argv[])
#include <iostream>
double sum(double a,double b);
void menu();
double subtract(double a,double b);
double multiply(double a,double b);
double divide(double a,double b);
using namespace std;
int main(int argc, char *argv[])

Jan 26, 2013 Write a C program to MAke Simple calculator Exercise 1) Write a program and call it calc.cpp which is the basic calculator and receives three values from input via keyboard. The first value as an operator (Op1) should be a char type and one of (+. C Program to Make a Simple Calculator Using switch.case In this example, you will learn to create a simple calculator in C programming using the switch statement. To understand this example, you should have the knowledge of the following C programming topics.
I would call this as a C style of writing C programs. Please don't get me wrong but you need to start thinking in object oriented way so that you can leverage the true power of C. I would recommend you to make a C class called calculator and think on the design of the class for a bit before starting to code.

#anonymous Couldn't you just make it simple and do it like this: #include <iostream> using namespace std; int main() { float a , b; int process; cout << 'Hello. I am a calculator. Please do not enter any letters while using me. Thanks.' << endl; while (true){ cout << 'Type in a number (0 to exit): '; cin >> a; if (a 0) return 0; else cout << ' Enter a second number: '; cin >> b; cout << 'Would you like to add(1), subtract(2), multiply(3), or divide(4) your numbers? '; cin >> process; if (process 1) cout << 'The sum of the numbers is ' << a + b << endl; else if (process 2) cout << 'The difference of the numbers is ' << a - b << endl; else if (process 3) cout << 'The product of the numbers is ' << a * b << endl; else if (process 4) cout << 'The quotient of the numbers is ' << a / b << endl; else if (process != 1 , 2 , 3 , 4) cout << 'Please type a number 1-4.' << endl; } } This provides a program that acts as a calculator until the user types in 0. 2015-07-08 |

How To Make Calculator In Dev C++
So I have been working on a program that takes two integers and calculates addition,subtraction,multiplication,division, and modular division. So far I think I have everything correct to make it run...I just can't figure out how to rewrite it using functions. Any help would be appreciated. Thank you.
#include<iostream>
using namespace std;
int main()
{
int num1, num2, selection;
cout << 'Please enter an integer: ';
cin >> num1;
cout << 'Please enter another integer: ';
cin >> num2;
cout << 'nnn';
cout << 'Select the desired function:n';
cout << '1. Additionn';
cout << '2. Subtractionn';
cout << '3. Multiplicationn';
cout << '4. Divisionn';
cout << '5. Modular Divisionn';
cout << 'Selection: ';
cin >> selection;
cout << 'nnn';
switch(selection)
{
case 1:
cout << 'The sum of ' << num1 << ' and ' << num2 << ' is ' << num1+num2 << endl;
break;
case 2:
cout << 'The difference of ' << num1 << ' and ' << num2 << ' is ' << num1-num2 << endl;
break;
case 3:
cout << 'The product of ' << num1 << ' and ' << num2 << ' is ' << num1*num2 << endl;
break;
case 4:
cout << 'The quotient of ' << num1 << ' and ' << num2 << ' is ' << num1/num2 << endl;
break;
case 5:
cout << 'The remainder of ' << num1 << ' and ' << num2 << ' is ' << num1%num2 << endl;
break;
default:
cout << 'Invalid selectionn';
}
return 0;
