Cyclomatic Complexity of multiple if statements

Question

if (k =  = 1) 
        r  +  =  a;
else if (k =  = 2) 
        r  +  =  b;
else if (k =  = 3) 
        r  +  =  c;
else  
        r  +  =  d;


switch (k) {
    case 1:
    r   +  =  a;
    break;
    case 2:
    r   +  =  b;
    break;
    case 3:
    r   +  =  c;
    break;
    default:
    r   +  =  d;
    break;
    }

I am trying to understand whether for both the multiple if statement and the switch case the sample control flow diagram is the below diagram. I am sure that it is true for the switch case but i am unable to draw one for the multiple if statement

The switch statement is nothing but syntactic sugar for the multiple if/else. The control flows are exactly the same. So is the cyclomatic complexity.

except that a switch statement _MAY_ build a jump table, instead of cascading ifs – Gunther Schulz Mar 04 '20 at 10:18
