Question

CC++

Compiler: CPP (gcc-5.x) 0 Simple Calculator Given two integers and a string, create a simple calculator which performs the following operations: • Addition if the string is "+" • Difference if the string is "-" Multiplication if the string is "*" • Return quotient (obtained by dividing the first number by the second) if the string is "/" • Return greater value if the string is "max" • Return lesser value if the string is "min" solution.cpp 2 Create a function: solution that accepts two integers and a string, and returns the operation result based on the rules given above. 6 Input 8 5 10 solution.cpp 1 - #include<iostream> #include<cstdio> 3 using namespace std; 4 5 class ProblemSolution{ public: 7 int solution(int N); }; 9 10 int ProblemSolution :: solution(int N) 11 { 12 //write your code here 13} 14 15 //Your program will be evaluated by this main method and several test cases. 16 int main() 17 { 18 int N; 19 cin >> N; 20 ProblemSolution problemSolution; 21 cout << problem Solution.solution(N); 22 } Output 15 Note : • If the string is not a valid operator, then return -1. • If the operation specified is division and the divisor is zero, then return-2. + Test Case(s)

Answer 1

Ans

code:-

#include <iostream>

#include<string>

using namespace std;

int solution(string s,int num1,int num2){

//if operation is addition

if(s=="+")

return num1+num2;

//if operation is subtraction

else if(s=="-")   

return num1-num2;

//if operation is multiplication

else if(s=="*")   

return num1*num2;

//if operation is division

else if(s=="/"){ //divide by zero

if(num2==0) return -2;

return num1/num2;}

//if operation is max   

else if(s=="max")

{//if num1 is max

if(num1>num2) return num1;

else return num2;}

//if operation is to find the min   

else if(s=="min") {

//if num1 is min

if(num1<num2) return num1;

else return num2;

}

//if no match return -1

return -1;

}

int main()

{

string s;

int num1,num2;

cin>>s;

cin>>num1;

cin>>num2;

cout<<solution(s,num1,num2);

return 0;

}
