Question

1)write an algorithm to find the area of a rectangular using pseudocode

2)write an algorithm to find the mean of 5 numbers.

3)write an algorithm to find wether a given number is even or odd

Answer 1

1)

input: x,y \\width, length of a rectangular

$S:=x\cdot y$

output: S \\ area of a rectangular

2)

input: $x_1, x_2,x_3,x_4,x_5$ \\ 5 numbers

$m=\frac{x_1+ x_2+x_3+x_4+x_5}{5}$

output: m \\ the mean of 5 numbers

3)

input: x \\ number

if ($x\%2==0$ ) \\ check whether a given number is divisible by 2

then otput: x is even

else output: x is odd
