int x;
int y;
cin >> x;
y = 3;
if (x/y > 12)
cout << "Good Morning";
else
cout << "Good Afternoon";
return 0;
}

Cardinality

Writing data on the data file requires ______________ header file.

#include
void main() {
char ch;
cin >> ch;
switch(ch) {
case 'A':
cout << "A Grade";
break;
case 'B':
cout << "B Grade";
break;
case 'C':
cout << "C Grade";
break;
case 'D':
cout << "D Grade";
break;
default:
cout << "NO Grade";
}
}

Data Redundancy

A pointer is a variable that refers to the location of another variable.

Objects

A pointer is a variable that refers to the location of another variable.

void main()
{
int x = 88;
int *y = &x;
cout<<*y;
}

Object pointers are used to create objects during run time.

#include
int main() {
int x;
int y;
cin >> x;
y = 3;
if(x/y < 12)
cout << "Good Morning";
else
cout << "Good Afternoon";
return 0;
}
