Computer Science Exercise 4.13 4. Write a C++ program to
display even numbers, odd
numbers, or prime numbers
1. Write a C++ program that displays the
which lie within a range
Pascal triangle, as shown in Figure 4.52,
entered by the user.

when a user enters the power of expansion.
5. What is printed by the
following code fragment?
int x = 0;
do {
cout << x << “ “;
x++;
} while (x < 10);
cout << ‘\n’;
Figure 4.52: Output of the program
2. Use for loop to write a C++ program Functions
which outputs the multiplication table as
shown in Figure 4.53: Concept of functions
In programming, you can
sometimes find the same
instruction is applied repeatedly
throughout the main program.
The instruction does not iterate
the solution according to the
condition like what is happening
within the loop. Still, it is used
repeatedly through the program
according to the user tasks. To
avoid retyping such instructions

many times within the main
3. Create a simple calculator using C++ program, you can use a function.
programming language to solve the A function is a block of code
factorial of a number and read an exponent in a program which run only
when the user enters the base and power of when it is called. For example,
a particular exponent. A calculator should a program has a block of code
that calculates interest of money
allow the user to choose either to solve deposited by one customer in a
factorial or exponent of the number using bank. We do not want to rewrite
a switch case statement. the same instructions, if we wish
