Answer:
// Program is written in Coral Programming Language
// Comments are used for explanatory purpose
// Program starts here
// Variable declaration
float f0
int numkey
//Prompt user for input
Put "Enter Initial Key Frequency: " to output
f0 = Get next input
//Initialize number of keys
numkey = 1
//Print first key frequency
Put "Key Frequencies: " to output
Put f0 to output
put " " to output
for numkey = 1; numkey <= 4; numkey = numkey + 1
//Calculate next frequency
f0 = f0 * RaiseToPower(2,(1.0/12.0))
//Print Frequency
Put f0 to output
Put " " to output
//End of Loop
//End of program
Explanation:
Line 1 to Line 4 are comments
Line 5 and 6 are for variable declarations;
On line 5, variable f0 is declared as float
On line 6, variable numkey is declared as integer
Line 7 is a comment
Line 8 prompts user for input
On line 9, the user input us saved in variable f0
Line 11 initialized numkey to 1
Line 13 prints the string "Key Frequencies: " without the quotes
Line 14 prints the value of f0
Line 15 prints a blank
So, if for instance f0 = 440
Line 14 and 15 will print "440 " without the quote
Take note of the space after 440
Line 16 to 22 calculate and print the next 4 frequency using the given formula
