Gradeup Test Series

Question

Consider the following information of a source code. 

• $10$ operators are used which includes 4 unique operators. 
• $6$ operands are used which include 4 unique operands. 

Estimate the program length.

• A. $8$
• B. $12$
• C. $32$
• D. $16$

Answer 1

	Total	Unique
operators	N1 = 10	n1 = 4
operands	N2 = 6	n2 = 4

Program length ( N ) = N1 + N2 = 10 + 6 = 16

Vocabulary (n) = n1 + n2  = 4 + 4 = 8

Volume = $N.log_{2}n = 16.log_{2}8 = 16*3 = 48$

Comments

Thanks for the solution. But I do not understand the concept behind it. Can you please post a reference link from where i can study about this topic.

Thank you :)

Answer 2

Estimated program length = $n_1\log_{2}n_1 + n_2\log_{2}n_2 =$ $4\log_{2}4 + 4\log_{2}4 = 8\log_{2}4 = 8*2 = 16.$

Program Length = $N_1 + N_2 = 10 + 6 = 16.$

Difference between two is – Estimated program length is used before the development of the software or program and Program length is calculated after development of software or program.
