Write a C program to calculate salary raise for employees. If salary is between$ 0 < $ 30000 the rate is 7.0%If salary is bet

ween$ 30000 <= $ 40000 the rate is 5.5%If salary is greater than$ 40000 the rate is 4.0%1. Let the user enter salary. Allow the user to enter as many salaries as the user wishes until the user enters a negative salary to quit. User can also decides to quite immediately after starting the program. Pick the proper loop.2. Calculate the raise, new salary, total salary, total raise, and total new salary.3. Sample input and output (leftmost column is user input): Salary Rate Raise New Salary Salary: 25000 25000.00 7.00 1750.00 26750.00 Salary: 30000 30000.00 5.50 1650.00 31650.00 Salary: 35000 35000.00 5.50 1925.00 36925.00 Salary 40000 40000.00 5.50 2200.00 42200.00 Salary: -1 Total 42200.00 7525.00 137525.00 Process returned 0 (0x0) execution time: 55.237 s Press any key to continue.

Answer:

Written in C

#include <stdio.h>

int main(){

   float salary,rate,raise,newsalary,totalsalary = 0.0 ,totalraise = 0.0 ,totalnewsalary = 0.0;

   printf("Enter negative input to quit\n");

   printf("Salary: ");

   scanf("%f", &salary);

   while(salary>=0){

   if(salary>=0 && salary <30000){

       rate = 0.07;

   }

   else if(salary>=30000 && salary <=40000){

       rate = 0.055;

   }

   else{

       rate = 0.04;

   }

   

   raise = rate * salary;

   newsalary = salary + raise;

   totalraise +=raise;

   totalsalary+=salary;

   totalnewsalary+=newsalary;

   printf("Salary: %.2f\n", salary);

   printf("Rate: %.2f\n", rate);

   printf("Raise: %.2f\n", raise);

   printf("New Salary: %.2f\n", newsalary);

   printf("Salary: ");

   scanf("%f", &salary);

   }

   printf("Total Salary: %.2f\n", totalsalary);

   printf("Total New Salary: %.2f\n", totalnewsalary);

   printf("Total Raise: %.2f\n", totalraise);  

   return 0;

}

Explanation:

The declares all necessary variables as float

   float salary,rate,raise,newsalary,totalsalary = 0.0 ,totalraise = 0.0 ,totalnewsalary = 0.0;

This tells the user how to quit the program

   printf("Enter negative input to quit\n");

This prompts user for salary

   printf("Salary: ");

This gets user input

   scanf("%f", &salary);

The following iteration is repeated until user enters a negative input

   while(salary>=0){

This following if conditions check for range of salary and gets the appropriate rate of salary raise

<em>    if(salary>=0 && salary <30000){</em>

<em>        rate = 0.07;</em>

<em>    }</em>

<em>    else if(salary>=30000 && salary <=40000){</em>

<em>        rate = 0.055;</em>

<em>    }</em>

<em>    else{</em>

<em>        rate = 0.04;</em>

<em>    }    </em>

This calculates the raise by multiplying the salary by the rate of increment

   raise = rate * salary;

This calculates the new salary

   newsalary = salary + raise;

This calculates the total raise

   totalraise +=raise;

This calculates the total salary

   totalsalary+=salary;

This calculates the total new salary

   totalnewsalary+=newsalary;

This prints the salary

   printf("Salary: %.2f\n", salary);

This prints the rate of increment

   printf("Rate: %.2f\n", rate);

This prints the raise in salary

   printf("Raise: %.2f\n", raise);

This prints the new salary

   printf("New Salary: %.2f\n", newsalary);

This prompts user for salary input

   printf("Salary: ");

This gets user input for salary

   scanf("%f", &salary);

   } The while loop ends here

This prints the total salary

   printf("Total Salary: %.2f\n", totalsalary);

This prints the total new salary

   printf("Total New Salary: %.2f\n", totalnewsalary);

This prints the total raise in salary

   printf("Total Raise: %.2f\n", totalraise);  

   return 0;

How to do the for loop in python

To loop through a set of code a specified number of times, we can use the range() function, The range() function returns a sequence of numbers, starting from 0 by default, and increments by 1 (by default), and ends at a specified number.

Using recursion, write a program that asks a user to enter the starting coordinates (row, then column), the ending coordinates (
Luden [163]

Answer:

The program in Python is as follows

def Paths(row,col):

if row ==0 or col==0:

 return 1

return (Paths(row-1, col) + Paths(row, col-1))

row = int(input("Row: "))

col = int(input("Column: "))

print("Paths: ", Paths(row,col))

Explanation:

This defines the function

def Paths(row,col):

If row or column is 0, the function returns 1

<em> if row ==0 or col==0: </em>

<em>  return 1 </em>

This calls the function recursively, as long as row and col are greater than 1

<em> return (Paths(row-1, col) + Paths(row, col-1))</em>

The main begins here

This prompts the user for rows

row = int(input("Row: "))

This prompts the user for columns

col = int(input("Column: "))

This calls the Paths function and prints the number of paths

print("Paths: ", Paths(row,col))
