程序打印一个数字的乘法表

给定数字n作为输入，我们需要打印其表。

例子 ：

Input :  5
Output : 5 * 1 = 5
         5 * 2 = 10
         5 * 3 = 15
         5 * 4 = 20
         5 * 5 = 25
         5 * 6 = 30
         5 * 7 = 35
         5 * 8 = 40
         5 * 9 = 45
         5 * 10 = 50

Input :  8
Output : 8 * 1 = 8
         8 * 2 = 16
         8 * 3 = 24
         8 * 4 = 32
         8 * 5 = 40
         8 * 6 = 48
         8 * 7 = 56
         8 * 8 = 64
         8 * 9 = 72
         8 * 10 = 80
         8 * 11 = 88
         8 * 12 = 96

示例1：最多显示10个乘法表

C++

// CPP program to print table of a number
#include 
using namespace std;
 
int main()
{
    int n = 5;  // Change here to change output
    for (int i = 1; i <= 10; ++i)
        cout << n << " * " << i << " = " 
             << n * i << endl;
    
    return 0;
}

Java

// Java program to print table
// of a number
import java.io.*;
 
class table
{  
    // Driver code
    public static void main(String arg[])
    {  
        // Change here to change output
        int n = 5;
         
        for (int i = 1; i <= 10; ++i)
            System.out.println(n + " * " + i +
                               " = " + n * i);
    }
}

Python

# Python Program to print table
# of a number upto 10
 
def table(n):
    for i in range (1, 11):
         
        # multiples from 1 to 10
        print "%d * %d = %d" % (n, i, n * i)
 
# number for which table is evaluated
n = 5
table(n)

C#

// C# program to print
// table of a number
using System;
 
class GFG
{
    // Driver code
    public static void Main()
    {
        // Change here to
        // change output
        int n = 5;
         
        for (int i = 1; i <= 10; ++i)
            Console.Write(n + " * " + i +
                              " = " + n *
                               i + "\n");
    }
}

Javascript

 
// Javascript program to print
// table of a number
 
// Driver Code
 
// Change here to change output
let n = 5;
for (let i = 1; i <= 10; ++i)
    document.write( n + " * " +i +
            " = " + n *
                i +"<br>");

输出 ：

5 * 1 = 5
5 * 2 = 10
5 * 3 = 15
5 * 4 = 20
5 * 5 = 25
5 * 6 = 30
5 * 7 = 35
5 * 8 = 40
5 * 9 = 45
5 * 10 = 50

上面的程序最多只能计算10个乘法表。
下面的程序是对上面程序的修改，在该程序中，还要求用户输入应该显示乘法表的范围。
示例2：显示乘法表到给定范围

C++

// CPP program to print table over a range.
#include 
using namespace std;
int main()
{
    int n = 8;   // Change here to change input number
    int range = 12; // Change here to change result.
    for (int i = 1; i <= range; ++i)
        cout << n << " * " << i << " = "
            << n * i << endl;
    return 0;
}

Java

// Java program to print table
// over given range.
import java.io.*;
 
class table
{  
    // Driver code
    public static void main(String arg[])
    {  
        // Change here to change input number
        int n = 8;
         
        // Change here to change result
        int range = 12;
         
        for (int i = 1; i <= range; ++i)
            System.out.println(n + " * " + i
                             + " = " + n * i);
    }
}

Python

# Python Program to print table
# of a number given range
 
def table(n, r):
    for i in range (1, r + 1):
         
        # multiples from 1 to r (range)
        print "%d * %d = %d" % (n, i, n * i)
 
# number for which table is evaluated
n = 8
 
# range upto which multiples are to be calculated
r = 12
table(n,r)

C＃

// C# program to print
// table over given range.
using System;
 
class GFG
{
    // Driver code
    public static void Main()
    {
        // Change here to
        // change input number
        int n = 8;
         
        // Change here to
        // change result
        int range = 12;
         
        for (int i = 1; i <= range; ++i)
            Console.Write(n + " * " +
                          i + " = " +
                          n * i + "\n");
    }
}

Java脚本

 
// Javascript program to print
// table of a number in range
 
// Driver Code
// Change here to
// change input number
 
let n = 8;
 
// Change here to
// change result.
let range = 12;
for (let i = 1; i <= range; ++i)
    document.write( n + " * " +i +
            " = " + n *
                i +"<br>");

输出：

8 * 1 = 8
8 * 2 = 16
8 * 3 = 24
8 * 4 = 32
8 * 5 = 40
8 * 6 = 48
8 * 7 = 56
8 * 8 = 64
8 * 9 = 72
8 * 10 = 80
8 * 11 = 88
8 * 12 = 96
