Question

Составить программу для вывода в столбик таблицу умножения на 9.

Answer 1

var a:array[1..10,1..10]of integer;

i,j:integer;

begin

for i:=2 to 10 do a[i,1]:=i-1;

for i:=2 to 10 do a[1,i]:=i-1;

 

for i:=2 to 10 do

for j:=2 to 10 do

a[i,j]:=a[i,1]*a[1,j];

 

for i:=1 to 10 do begin

for j:=1 to 10 do

write(a[i,j]:3); if j=10 then writeln; end;

 

end.

Answer 2

Program to Display the Multiplication Table of 9

Here is a program in Python to display the multiplication table of 9 in a column format:

for i in range(1, 11):
    print(f"9 x {i} = {9 * i}")

The above program uses a `for` loop to iterate through the numbers 1 to 10. For each iteration, it calculates the product of 9 and the current number (`9 * i`) and prints it in the format "9 x i = result".

The output of the program will be:

9 x 1 = 9
9 x 2 = 18
9 x 3 = 27
9 x 4 = 36
9 x 5 = 45
9 x 6 = 54
9 x 7 = 63
9 x 8 = 72
9 x 9 = 81
9 x 10 = 90

This program can be easily modified to display the multiplication table of any other number by changing the value of the constant (`9` in this case) in the program.

I hope this helps! Let me know if you have any further questions.
