Dear Student,
Term End practical examination Dec 2015 for MCA programme is scheduled at IGNOU Study Centre, UPTEC Computer Consultancy, Rana Pratap Marg, Lucknow from 10th January 2016. It is advised to contact examination supdt one day prior to the practical examination to know about your session and batch. Course wise list is also uploaded in RC Lucknow website.

Design a flow chart and write an interactive program for the problem given below: Assume that the United States of America uses the following income tax code formula for their annual income:
First US$ 5000 of income: 0% tax
Next US$ 10,000 of income: 10% tax
Next US$ 20,000 of income: 15% tax
An amount above US$ 35,000: 20% tax.
For example, somebody earning US$ 38,000 annually
would owe US$ 5000 X 0.00+ 10,000 X 0.10 + 20,000 X 0.15 + 3,000 X 0.20,
which comes to US$ 4600. Write a program that uses a loop to input the income and calculate and report the owed tax amount. Make sure that your calculation is mathematically accurate and that truncation errors are eliminated
#include<stdio.h>
#include<conio.h>
void main()
{
float income,i=0,j=0,k=0,tax=0;
clrscr();
printf("\n\n\t\tEnter Your Income Tax -> ");
scanf("%f",&income);
/*--------Calculate The Tax---------*/
if(income>35000)
{
income=income-35000;
i=10000*.10;
j=20000*.15;
k=income*.20;
tax=i+j+k;
printf("\n\n\t\tYour Tax is %f",tax);
}
else if(income>20000 && income<=35000)
{
income=income-15000;
i=10000*.10;
j=income*.15;
tax=i+j;
printf("\n\n\t\tYour Tax is %f",tax);
}
else if(income>10000 && income<=20000)
{
income=income-15000;
i=10000*.10;
j=income*.15;
tax=i+j;
printf("\n\n\t\tYour Tax is %f",tax);
}
else if(income>5000 && income<=10000)
{
income=income-5000;
