Answer:
#include<iostream>
using namespace std;
int main(){
double num1, num2;
char ope;
cout<<"Enter two numbers: ";
cin>>num1>>num2;
cout<<"Enter an operator +, -, /, * :";
cin>>ope;
if(ope == '+'){
cout<<num1+num2;}
else if(ope == '-'){
cout<<num1-num2;}
else if(ope == '*'){
cout<<num1*num2;}
else if(ope == '/'){
cout<<num1/num2;}
else{
cout<<"Invalid operator";}
return 0;
}
Explanation:
#include<iostream>
using namespace std;
int main(){
This line declares num1 and num2 as double
double num1, num2;
This line declares ope as a character
char ope;
This line prompts user for user inputs
cout<<"Enter two numbers: ";
This line gets user inputs
cin>>num1>>num2;
This line prompts user for operator
cout<<"Enter an operator +, -, /, * :";
This line gets the operator
cin>>ope;
This condition checks if the operator is +. If yes, it adds and prints the result
if(ope == '+'){
cout<<num1+num2;}
This condition checks if the operator is -. If yes, it subtracts and prints the result
else if(ope == '-'){
cout<<num1-num2;}
This condition checks if the operator is *. If yes, it multiplies and prints the result
else if(ope == '*'){
cout<<num1*num2;}
This condition checks if the operator is /. If yes, it divides and prints the result
else if(ope == '/'){
cout<<num1/num2;}
This checks for invalid operators
else{
cout<<"Invalid operator";}
return 0;
}
