Code Complexity

Posted on by

Compare the complexities of the two pieces of code A & B using these two metrics LOC and cyclomatic-complexity. What conclusions can you draw about the relative complexity of the code?

Code A

Code B
int i = 1;while(i < =5){

playACard(i);

if (playerHasWon(i))

break;

i++

}

 int j = 0;int i = 2;

j = i;

j = j + i;

j++;

System.out.println (j);

System.out.println
Code A and B both have the same amount of LOC which is 7 according to the LOC metric which counts the physical Lines Of Code.
Code A has a cyclometric-complexity of 3 (1 for if, 1 for while loop and 1 for the whole method), while code B has a complexity of 1 (1 for the method). Code A is more complex than code B according to the cyclomatic-complexity metric as code A has a while loop and an if statement while code B is linear.
