C Program to multiplication table using Array

C Program to multiplication table using Array

In this tutorial , we will discuss about C Program to multiplication table using Array

We can display multiplication in C language of various way. In this tutrorial ,we will learn how to display multiplication table using array in C language

Here, we can print 12 * 12 multiplication table using  array with for loop

C code to multiplication table using Array- #1

Program 1

// C Program to multiplication table using Array
#include <stdio.h>

int main() {
    int num,i;
    int table[10];
    // Array to store multiplication result;
    printf("Enter a number as you wish:");
    //input a number to generates multiplication table
    scanf("%d",&num);
    
    //Store the multiplication table in the array
    for(i=0; i<10; i++){
        table[i]=num*(i+1);
    }
    
    //Display the multiplication table
    printf("Multiplication table of %d\n",num);
for(i=0; i<10; i++){
        printf("%d * %d =%d\n",num,i+1,table[i]);
    }
    return 0;
}

When the above code is executed, it produces the following result

Enter a number as you wish:12
Multiplication table of 12
12 * 1 =12
12 * 2 =24
12 * 3 =36
12 * 4 =48
12 * 5 =60
12 * 6 =72
12 * 7 =84
12 * 8 =96
12 * 9 =108
12 * 10 =120

Explanation

The program  asks the user for a number

it uses an array to store the results of multiplying the number by integer from 1 to 10

A for loop calculates and stores these results in the array

Another for loop displays the results stored in the array in a formatted manner

C code to multiplication table using Array -#2

Program 2

// C Program to multiplication table using Array
#include <stdio.h>

int main() {
    int num,i;
    int table[10][2];
    // Array to store multiplication value;
    printf("Enter a number as you wish:");
    //Asking user for a number
    
    //reading the number to generates multiplication table
    scanf("%d",&num);
    
    //Storing the multiplication factors and results in the array
    for(i=0; i<10; i++){
        table[i][0]=(i+1);//multipliers(1 to 10)
        table[i][1]=num *(i+1);//results
    }
    
    //Displaying the multiplication table 
    printf("Multiplication table of %d\n",num);
    printf("...............................\n");
     printf("| Multiplier |  Results | \n");
     printf("...............................\n");
    for(i=0; i<10; i++){
        printf("|    %2d    |  %4d    |\n",table[i][0], table[i][1]);
    }
    return 0;
}

When the above code is executed, it produces the following result

Enter a number as you wish:12
Multiplication table of 12
………………………….
| Multiplier | Results |
………………………….
|         1         |        12       |
|        2         |       24        |
|        3         |       36        |
|        4         |       48       |
|        5          |      60       |
|        6          |       72      |
|        7          |       84      |
|       8          |       96       |
|       9          |      108      |
|      10         |      120      |
