Jun 22, 2016  C – Program to Make Simple calculator in C. Numark mixtrack pro ii driver. Write a program and call it calc.cpp which is the basic calculator and receives three values from input via keyboard. Program should receive another two operands (Num1, Num2) which could be float or integer.

C Program to Create Simple Calculator Example 1. This calculator program in C helps the user to enter the Operator (+, -,., or /) and two values. Using those two values and operand, it will perform Arithmetic Operations. For this C calculator program example, we used the Switch case to check which operand is inserted by the user. Jun 22, 2016 C – Program to Make Simple calculator in C June 22, 2016 admin C 2 Write a program and call it calc.cpp which is the basic calculator and receives three values from input via keyboard. C simple calculator program which uses while loop, functions and switch statement. Having functions additions subtraction,multiplication,division,Square root, factorial and exponential function. Beginners can also use it for mini c project by adding more functionalities like filing they can improve it. Nov 19, 2017  The key to making a calculator isn’t about drawing buttons or a fake display on the screen, it’s understanding how to manipulate a mathematical expression entered as a series of text characters to give an answer. This requires a parser. Jul 24, 2017  hello guys today I will show you how to make a BMI calculator in dev c. Sorry I can not show you the code in the description as it does not allow angle brackets. Hello As part of a personal project, I need to make a console based Scientific calculator. It needs to be able to add, subtract, multiply and divide a large amount of numbers per command (eg: 2+2+2+2+2+2.9/7.sin 45- 88.277) and be able to manipulate numbers correctly using BIDMAS.

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[])

{
int c;
double r,a,b;
menu();
cout<<'Enter your choice: '<<endl;
cin>>c;
switch(c){
case 1:cout<<'Enter a: ';cin>>a;
cout<<'Enter b: ';cin>>b;
r=sum(a,b);
cout<<'Result:'<<r<<endl;break;
case 2:cout<<'Enter a: ';cin>>a;
cout<<'Enter b: ';cin>>b;
r=subtract(a,b);
cout<<'Result:'<<r<<endl;break;
case 3:cout<<'Enter a: ';cin>>a;
cout<<'Enter b: ';cin>>b;
r=multiply(a,b);
cout<<'Result:'<<r<<endl;break;
case 4:cout<<'Enter a: ';cin>>a;
cout<<'Enter b: ';cin>>b;
r=divide(a,b);
cout<<'Result:'<<r<<endl;break;
default:cout<<'Invalid choice'<<endl;
}
system('PAUSE');
return EXIT_SUCCESS;
}
double sum(double a,double b){
double result_sum= a+b;
return result_sum;
}
double subtract (double a, double b){
double result_subtract =a-b;
return result_subtract;
}
double multiply (double a, double b){
double result_multiply =a*b;

double divide (double a, double b){
double result_divide =a/b;
return result_divide;
}

#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

• The first value as an operator (Op1) should be a char type and one of (+, -, *, /, s) characters with the following meanings:
  • ‘-’ for subtraction (num1 – num2)
  • ‘/’ for division (num1 / num2)
• Program should receive another two operands (Num1, Num2) which could be float or integer.
• The program should apply the first given operator (Op1) into the operands (Num1, Num2) and prints the relevant results with related messages in the screen.
• Swap operator exchanges the content (swap) of two variables, for this task you are not allowed to use any further variables (You should use just two variables to swap).
