22. What will be the output of the given code? #include using namespace std; int main() { } int a; int b = 1; int arr[5] = {1,2,3,4,5}; a = arr[b++]*5 + (9/b); cout<

#include <iostream> using namespace std; int rectArea (int len, int wid) { return len * wid; } int main () { int length, width; cin >> length >> width; cout << "The area of a " << length << " by " << width << " rectangle is " << /*add code to call the reacArea function */ << "." << endl; return 0; }

#include <iostream> #include <string> #include <cstdlib> using namespace std; template<class T> class A { public: T func(T a, T b){ return a/b; } };   int main(int argc, char const *argv[]) { A <float>a1; cout<<a1.func(3,2)<<endl; cout<<a1.func(3.0,2.0)<<endl; return 0; }       Give output for this code.
