Question

When you write code with conditional execution,

the reason why you should use 3 or less conditional execution instructions is ( A )

What is A ?

Answer 1

In the given statement , the reason why we should use 3 or less conditional execution instructions is because :

We can only use conditional keywords and create a block which consists on one or many blocks of instructions which get executed if the the conditions are satisfied. So we use 3 keywords IF-Then-Else to set conditional execution instructions.

for instance, in pseudo code we can say :

if( condition 1 ) {do something in 1}

else if(condition 2) { do something in 2}

else {do something else}

so as we see in the pseudo code above, we can set conditional statements and only that block gets executed if the condition 1 is True. If it is False, ie., the condition 1 does not satisfy, we check in the else if block, if condition 2 is satisfied or true then only that corresponding block gets executed. Otherwise else condition block is executed.

Instead of all 3 of these instructions, we can use just the If block or If and Else block.

This format maintains code readability, saves memory and is much easier to debug through.
