Answer 1

Step 1) RELAX bro, in programming its bad to get fustrated, if you are take a break or something.

You forgot to use the line "using namespace std;" so either you need to use the namespace std, or you need to use the std class and the scope resoultion operator ( :: ) whenever you use cout...example

std::cout << "This is how you use it";

#include

using namespace std;

int main()
{
int a;
int my;
my = 15;

cout << "What do u think My age is?: ";
cin >> a;

if(a == my)
{
cout << "U have Guessed Right.. YEA!";
cout << endl << "Congradulation";
}
else
{
if(a < my)
{
cout << "GO HIGHER" << endl;
}
else
{
cout << "TOO HIGH..Go LOWER" << endl;
}
}
main();
return 0;
}

You need this:

#include
using namespace std; // additional string.

It is very suspicious that your compiler does not catch such things: namespace is strongly required here.
