Concept explainers

Control structures

Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.

Switch Statement

The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.

1. The calculator program will first ask the user for the mode to operate in (Standard or Scientific)
Scientific
Sample Output:
Enter the calculator mode: Standard/Scientific?
2. The program should then ask the user for the operation to execute (+,-, *, /, sin x, cos x, tan
x)
Sample Output
for Scientific mode:
Enter + for addition, '-' for subtractions, '*' for multiplication, '/' for division, 'sin'
for sin x, 'cos' for cos x, 'tan' for tan x:
sin
Sample Output for Standard mode:
The calculator will operate in standard mode.
Enter + for addition, '-' for subtractions, '*' for multiplication, '/' for division
2a. If the user enters an invalid operator, output a message telling the user the input is invalid
and re-prompt the user for the operation again.
Sample Output for Scientific mode:
Enter + for addition, '-' for subtractions, '*' for multiplication, '/' for division, 'sin'
for sin x, 'cos' for cos x, 'tan' for tan x:
division
Invalid operator division
Enter + for addition, '-' for subtractions, '*' for multiplication, '/' for division, 'sin'
for sin x, 'cos' for cos x, 'tan' for tan x:
3
3. In order to know how many times the user will need to perform the operation, prompt the user for
the number of floating point values they want to enter (All numbers in this program are double), then
ask the user to enter the numbers.
35
9
Sample Output:
How many numbers do you want to add?:
Enter 3 numbers:
In this example the calculator will calculate 4 + 35+ 9. The calculated result will be 48.
The calculator should be able to perform the following operations:
2+3 = 5
2+6+1+1+1 = 11
1-2-90-91
10*2*3 = 60
10/2/5 = 1
cos (0)
1
sin (0)
0
tan (0) 0
Note: This calculator does NOT support multiple operations of varying operators in the expressions
like: 10+2-8
Note: Multiple numbers are only acceptable for the operations of (+,-, *, / ) not for (sin, cos, tan)
4. Display the result
Sample Output:
Result: 50.0
