Question

Write an algorithm and draw a flowchart to calculate
2^4 using a loop approach?
​

Answer 1

I'm not about to write a flow chart for you, but here's a quick demo of how to do it:

doPower(2, 4);

function doPower(base, power){

var result = 1, p;

for(p = 0; p < power; p++){

result *= base;

}

return result;

}

That function will only work for positive integer exponents of course.

Answer 2

An algorithm and flowchart to calculate 2^4 using a loop approach:

Algorithm:

Initialize a variable result to 1.

Start a loop from 1 to 4.

Inside the loop, multiply result by 2.

End the loop.

Display the value of result, which is the result of 2⁴

So, the algorithm initializes a variable result to 1. This is because
`2^0` is 1. Then, it starts a loop from 1 to 4. This means that the loop will run 4 times. Inside the loop, it multiplies result by 2.

This is because
`2^1 is 2, 2^2 is 4, 2^3` is 8, and
`2^4` is 16. The loop ends when the counter reaches 4. Finally, the algorithm displays the value of result, which is 16.
