JAVA LANGUAGE CODE
Postfix Calculator
by CodeChum Admin
One good implementation of computing infix expressions is to transform them to postfix and then evaluate via the postfix expression.
Infix expressions is the common way of writing arithmetic expressions. The binary operator come between them as shown below:
2 * 5 + 9 - 10 / 20
In postfix expressions, the operands come first before the operator:
2 5 * 9 + 10 20 / -
A stack can be used to evaluate postfix expressions. The operands are pushed onto the Stack and when an operator is found two operands are popped and the operation is performed and finally the result is pushed back onto the Stack.
The final answer will be the lone element of the Stack.
Input
The first line contains a positive integer n representing the number of postfix expressions. What follows are n postfix expressions themselves.

10 20 +
30 15 2 * +

Write these in Pseudocode
#1a – In pseudocode, write a call to a function that passes 1 Integer variable and 1 Integer array, and saves a Boolean value in return.
#1b – In pseudocode, write the function that accepts 1 Integer and 1 Integer array and returns a Boolean.
In the function, search the Integer array with a for-loop, and if the Integer parameter is found in the array, return false. If the Integer parameter is not found, return true.
#2a – In pseudocode, write a call to a module that passes 1 Integer variable, 1 Real variable, 1 String constant, and 1 String literal as arguments.
#2b – In pseudocode, write the module header that accepts 1 Integer, 1 Real, and 2 Strings as parameters.
#3 – This pseudocode has multiple problems. Fix the calling statement and the definition below so that the routine accepts 3 grades as parameters and returns the average into a variable.…

It is used to monitor one's health by determining whether one is underweight, overweight, has normal weight or is obese. It is computed based as follows (when using standard weight in pounds and height in inches): BMI = 703 x (weight/(height2)) Furthermore, people with BMI scores that are less than 18.5 are said to be underweight. Those with scores between 18.5–24.9 (inclusive) are of normal weight. Those with scores between 25–29.9 (inclusive) are said to be overweight. And those with scores 30 or higher are obese. Input The input is composed of two positive integers representing the weight in pounds and the height in inches. 140·65 Output A single line containing two values: the computed…arrow_forward// Return remainder after integer division // Global variables int a = 4; int b = 30; int main() { // Use registers for local variables int remainder; int divisor; } if (a > b) { } else { } remainder = a; divisor = b; } remainder = b; divisor = a; while (remainder > divisor) { remainder -= divisor; return remainder;arrow_forward
