cin a>>b>>c;
if(b == 1) {
cout<<"\n\n-excuting the operation...\n";
cout<<"\n The sum result is : ";
cout<<a+b;
if(b == 2) {
cout<<"multiplying "<<a <<"in "<<c << "the result is:\n "<<a*b;
if(b == 3)
cout<<"substricting " <<a <<" from "<<b<<"please wait...\n"<<"-the result is: "<<a-b;

if(b == 4) {
cout<<"dividing "<<a<<" by "<<b<<" please wait...d\n"<<"-the result is: "<<a/b;

}

Answer 1

UG.2 here is the fixed calculator
you missed a couple semicolons and the >> infront of cin >>

btw you have a+b a*b a-b a/b
b is the operator
should be a+c a*c a-c a/c
