    #include <iostream>
    #include <string>
    using namespace std;
    int main()
    {
        double Op1 = 10, Op2 = 5, Res;
        char Op;
        try 
        {   
            if (Op != '+' && Op != '-' && Op != '*' && Op != '/')
                throw Op;
            switch(Op)
            {
            case '+':
                Res = Op1 + Op2;
                break;
            case '-':
                Res = Op1 - Op2;
                break;
            case '*':
                Res = Op1 * Op2;
                break;
            case '/':
                Res = Op1 / Op2;
                break;
             }
             cout << "\n" << Op1 << " " << Op << " "<< Op2 << " = " << Res;
         }
         catch (const char n)
         {
             cout << n << " is not a valid operator";
         }
         return 0;
    }

is not a valid operator

Question 5 of 10

5. What will be the output of the following C++ code?

#include <iostream>
#include <string>
#include <cstdlib>
using namespace std;

void func(int a, int b)
{

	if(b == 0){
		throw "This value of b will make the product zero. " 
                      "So please provide positive values.\n";
	}
	else{
		cout<<"Product of "<<a<<" and  "<<b<<" is: "<<a*b<<endl;
	}
}

int main()
{
	try{
		func(5,0);
	}
	catch(const char* e){
		cout<<e;
	}
}

Product of 5 and 0 is: 0

This value of b will make the product zero. So please provide positive values.
