Input = Fourdigitnum
Output = digit1, digit2, digit3, digit4


Major Task (Module/Subproblems)

1. Receive Fourdigitnum
2. Extract the Fourdigitnum received
3. Remove the digit from the original number
4. Display digit
5. Repeat Step 2


1. Fourdigitnum ("Enter a four-digit positive integer: ")
Receive Fourdigitnum

2. digit1= (Fourdigitnum)/1000


3. (Fourdigitnum)%1000

Fourdigitnum=Fourdigitnum/100

digit2=Fourdigitnum

Fourdigitnum=Fourdigitnum/10

digit3= Fourdigitnum

Fourdigitnum=Fourdigitnum%10

digit4= Fourdigitnum


4. Display digit1, digit2, digit3, digit4

5. End Repeat

This IPO chart is close but needs two fixes: keep the Process row high-level (no language keywords or line-by-line arithmetic), and correct the arithmetic order so each place value is computed reliably. mixed implementation details into Process; is correct that a small change will generalize the solution beyond four digits.

Suggested IPO (concise, non-language-specific):
Input: a positive four-digit integer (or "an integer" if you want a general solution).
Output: the digits in order from most-significant to least-significant.
Process: validate input; extract each digit using either arithmetic or string conversion; present digits.

A robust general approach (arithmetic): repeatedly take the remainder by 10 to collect least-significant digits, divide by 10 to shift right, then reverse the collected digits to restore most-to-least order. This handles any length, is simple to implement, and avoids the indexing/offset mistakes that appear in the posted chart.

Example C++ implementation (general, handles any nonnegative integer):

#include <iostream>
#include <vector>
#include <algorithm>

int main() {
    long long n;
    if (!(std::cin >> n)) return 0;
    if (n < 0) n = -n;
    if (n == 0) { std::cout << 0 << '\n'; return 0; }

    std::vector<int> digits;
    while (n > 0) {
        digits.push_back(static_cast<int>(n % 10));
        n /= 10;
    }
    std::reverse(digits.begin(), digits.end());

    for (size_t i = 0; i < digits.size(); ++i)
        std::cout << digits[i] << (i + 1 < digits.size() ? ' ' : '\n');
}

Troubleshooting notes: to enforce exactly four digits, validate the numeric range or accept input as a string and check length (useful if you must preserve leading zeros). Remember integer division truncates; handle negative input explicitly. Keep the IPO Process descriptive and move the arithmetic details into your solution algorithm or code.

where's the code? also this algo will always work only for 4 digit numbers, with a little more effort you can convert it to a general code for any no. of digits in the number..

what code? this the IPO Chart

Here are my instruments

For IPO,
the I(nput) should be the name(s) you like to use to capture the input(s) of the problem. The O(utput) should be the name(s) you like to use to store the expected output(s) produced by your solution. Be sure all your identifiers/names are valid ones. Please refer to your class notes and text book for details about valid identifiers.
The P(rocess) section should have only description of what major tasks need to be completed in solving the problem. NO DETAILS about how to complete each task are needed. For instance, DO NOT say "subtract DEDUCTION from GROSS_PAY and save result in NET_PAY" in P(rocess) section. Say something like "Compute net pay." instead.
Leave the details about "How" to "Compute net pay." in your Solution Algorithm. So you can concentrate on one task at a time.
Absolutely NO C++ code or keyword of any kind should be used (they are not even needed) in Part I of the Assignment
