Objective:
1) Getting Familiar with input output statements.
2) Understanding different data types.
3) Understanding the use of arithmetic operators and performing calculations
4) Getting familiar with the const keyword
1. Write the following codes in your compiler, execute them and Write the output.
char grade = ‘A’;
cout << "Grade is :" << grade << endl;
Output:
int marks = 80;
cout << "Marks are :" << marks << endl;
Output:
int marks;
cout << "Enter marks: ";
cin >> marks;
cout << "Marks are:" << marks << endl;
Output:
float radius;
float pi = 3.14;
float circum;
cout << "Enter radius: ";
cin >> radius;
circum = 2 * pi * radius;
cout << "Circumference of circle with radius " << radius << " is "<< circum
<< endl;
