The following declaration, program, and program segment has errors. Locate as many as you can.
#include <iostream> using namespace std;class DumbBell;
{
int weight; public: void setWeight(int);
};void setWeight(int w)
{ weight = w; }int main()
{ DumBell bar; DumbBell.setWeight(200); cout << "The weight is " << bar.weight << endl; return 0;}
state whether the program base on the output is CORRECT or INCORRECT.
#include
using namespace std;
|| function declaration
int max(int num1, int num2);
int main () {
// local variable declaration:
int a = 100;
int b = 200;
int ret;
I| calling a function to get max value.
ret = max(a, b);
cout num2)
result = num1;
else
result = num2;
return result;
}
