C Program to Generate Multiplication Table!

Let’s write a simple C program to generate multiplication table. It’s fairly a simple program.

Here is a Short snippet to generate 7 times tables:

#include <stdio.h>
int main()
{
	//define the values
	int table_no = 7, upto = 10, i;
 
	//loop through till upto limit and print the table
	for (i=1; i<=upto; ++i){
	  printf("%d * %d = %d\n", table_no, i, table_no * i);
	}
	
    return 0;
}

Output:

7 * 1 = 7
7 * 2 = 14
7 * 3 = 21
7 * 4 = 28
7 * 5 = 35
7 * 6 = 42
7 * 7 = 49
7 * 8 = 56
7 * 9 = 63
7 * 10 = 70

Now let’s convert this to a dynamic multiplication table generator, to do that we need to get the table_no and upto limit from user instead of defining the values.

Here is the rewritten of the above program to get the values from user:

#include <stdio.h>
int main()
{
	int table_no, upto, i;

	//get the table no from user
	printf("Table no: ");
	scanf("%d", &table_no);
	
	//get the limit from user
	printf("Upto: ");
	scanf("%d", &upto);
 
 	//loop through the upto limit
	for (i=1; i<=upto; ++i){
	  printf("%d * %d = %d\n", table_no, i, table_no * i);
	}
	
    return 0;
}

Just go through the comments in the above program to understand it.

Example output of the above script:

Table no: 12
Upto: 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
12 * 11 = 132
12 * 12 = 144
