Nested For Loops (Multiplication Table)

In this problem, you will create a program that reads an integer n from standard input, uses nested for loops to control rows (1–n) and columns (1–n), computes the product of each pair, and displays an n×n multiplication table with values separated by spaces to standard output.

Learning Objective: Understand 2D repetitive processing with nested for loops

Overview

Placing a for loop inside another enables row-column 2D processing. A multiplication table is a classic example.

Input Format

n

• n: size of the table (positive integer)

Specifications

• Outer for controls rows (1–n), inner for controls columns (1–n)
• Display calculation results for each row separated by spaces

Sample Input

3

Sample Output

1 2 3
2 4 6
3 6 9
