Nested for loop to print multiplication tables up to a certain number.

A nested for loop is used to print multiplication tables up to a certain number by generating rows and columns of multiplication results. Here's the explanation of how to achieve this using nested loops

In this article, we will discuss how to print multiplication tables up to a certain number with its working example in the R Programming Language using R for loop conditions.

Syntax:

max_number <- 10  # Change this to the desired maximum number
for (i in 1:max_number) {
  for (j in 1:10) {  # Multiplication up to 10
    cat(i, "x", j, "=", i * j, "\n")
  }
  cat("\n")  # Print a blank line after each table
}

Example 1: Nested for loop to print multiplication tables

max_number <- 5

for (i in 1:max_number) {
  for (j in 1:10) {
    cat(i, "x", j, "=", i * j, "\n")
  }
  cat("\n")
}

Output:

Multiplication table for 1 :
1 x 1 = 1 
1 x 2 = 2 
1 x 3 = 3 
1 x 4 = 4 
1 x 5 = 5 
1 x 6 = 6 
1 x 7 = 7 
1 x 8 = 8 
1 x 9 =  9 
1 x 10 = 10 
Multiplication table for 2 :
2 x 1 = 2 
2 x 2 = 4 
2 x 3 = 6 
2 x 4 = 8 
2 x 5 = 10 
2 x 6 = 12 
2 x 7 = 14 
2 x 8 = 16 
2 x 9 = 18 
2 x 10 = 20 
Multiplication table for 3 :
3 x 1 = 3 
3 x 2 = 6 
3 x 3 = 9 
3 x 4 = 12 
3 x 5 = 15 
3 x 6 = 18 
3 x 7 = 21 
3 x 8 = 24 
3 x 9 = 27 
3 x 10 = 30 
Multiplication table for 4 :
4 x 1 = 4 
4 x 2 = 8 
4 x 3 = 12 
4 x 4 = 16 
4 x 5 = 20 
4 x 6 = 24 
4 x 7 = 28 
4 x 8 = 32 
4 x 9 = 36 
4 x 10 = 40 
Multiplication table for 5 :
5 x 1 = 5 
5 x 2 = 10 
5 x 3 = 15 
5 x 4 = 20 
5 x 5 = 25 
5 x 6 = 30 
5 x 7 = 35 
5 x 8 = 40 
5 x 9 = 45 
5 x 10 = 50 

• Set the value of the variable max_number to 5.
• Start an outer for loop that iterates through numbers from 1 to the value of max_number.
• Start an inner for loop that iterates through numbers from 1 to 10 for each value of i.
• Using the cat() function, print the multiplication expression in the format "i x j = i * j", followed by a newline character.
• End of the inner for loop.
• Print a blank line to separate the multiplication tables for each i value.
• End of the outer for loop.

Example 2: Nested for loop to print multiplication tables up to a certain number.

max_number <- 13

for (i in 11:max_number) {
  for (j in 1:10) {
    cat(i, "x", j, "=", i * j, "\n")
  }
  cat("\n")
}

Output:

11 x 1 = 11 
11 x 2 = 22 
11 x 3 = 33 
11 x 4 = 44 
11 x 5 = 55 
11 x 6 = 66 
11 x 7 = 77 
11 x 8 = 88 
11 x 9 = 99 
11 x 10 = 110 
12 x 1 = 12 
12 x 2 = 24 
12 x 3 = 36 
12 x 4 = 48 
12 x 5 = 60 
12 x 6 = 72 
12 x 7 = 84 
12 x 8 = 96 
12 x 9 = 108 
12 x 10 = 120 
13 x 1 = 13 
13 x 2 = 26 
13 x 3 = 39 
13 x 4 = 52 
13 x 5 = 65 
13 x 6 = 78 
13 x 7 = 91 
13 x 8 = 104 
13 x 9 = 117 
13 x 10 = 130

• Set the value of the variable max_number to 13.
• Start an outer for loop that iterates through numbers from 1 to the value of max_number.
• Start an inner for loop that iterates through numbers from 1 to 10 for each value of i.
• Using the cat() function, print the multiplication expression in the format "i x j = i * j", followed by a newline character.
• End of the inner for loop.
• Print a blank line to separate the multiplication tables for each i value.
