Question

C++ please

Problem 3: Write a C++ program that prompts the user to enter an integer of any length (but not more than 8- digits), the program then extracts and prints each digit in its respective column. For example, in the integer 436, 4 should be printed in the 4th column, 3 in the 3rd and 6 in the 6th column. Hint: you can use setw to solve this problem. Sample Input/Output Enter an integer of any length. 9836472 ...Printing each digit in its respective column... 1234567890 2 7 4 6 3 Enter an integer of any length. 9274 ...Printing each digit in its respective column... 1234567890 4 7 2 9

Answer 1

Program:

1 7 00 main.cpp 1 //Preprocessor directive to read and rite to the standard input/output stream 2 #include <iostream> 3 // Header field used to set width 4 #include <iomanip> 5 //Tells compiler that symbol names defined in the std namespace are to be brought into scope 6 using namespace std; 7 8 //Main function 9 int main() { 10 // Declare integer n 11 12 cout << "Enter an integer of any length. "; 13 //User input n 14 cin>>n; 15 cout <<"...Printing eachh digit in its respective column... \n"; 16 cout<<"1234567890\n"; 17 //Repeat till the last digit 18 while(n != 0) { 19 // Store the last digit int last_digit = n%10; 21 //If last digit = 0; Set width (space) to 10 22 if (last_digit==0){ 23 cout<<setw(10); 24 } int n; 20

main.cpp 25 26 27 28 29 30 //Else set width(space) to the number else{ cout<<setw(last_digit); } // Print the last digit cout<<last_digit; // Move to next line cout<<"\n"; //Remove the last digit n = 10; } 31 32 33 34 35 36 37 }

Output:

X clang++-7 -pthread -std=c++17 -o main main.cpp ./main Enter an integer of any length. 9836472 ...Printing eachh digit in its respective column... 1234567890 2 7 4 6 3 8 9

х clang++-7 -pthread -std=c++17 -o main main.cpp } ./main Enter an integer of any length. 9274 ...Printing eachh digit in its respective column... 1234567890 4 7 2 9

Summary:

1) Insert all the required headers (iostream, iomanip and using namespace std is optional as you call also use std inside the functions.)

2) Get the user input .

3) Repeat the while loop process till the user input has not digits left.

1) get the last digit

2) using setw() set the width/space as the last digit - If the digit is 0 setw() as 10 - ELse the last digit

3) Print the last digit

4) Set the user input with the last digit (Remove the last digit)

setw() - setw() in iomanip is used to set library width based on the parameter inside it.
