Table Program in C

This article will write the table programs using loops (for, do-while, and while loop) and functions (user-defined and recursion function) in the C programming language.

A table (or multiplication table) of numbers is generated by multiplying a constant number with an iterative number from 1 to 10 to get the table. In other words, we can get the table of a number by multiplying the given number with counting from 1, 2, 3, 4, 5, …, 9, 10. And on each iteration, the value of counting is incremented by 1, which goes up to 10, to print a complete table.

For example, suppose we want to write the table of 5 in C language. So, first, we take 5 as input from the user, and then, we use a loop or function that multiplies the number 5 by 1 (5 * 1), and then (5 * 2), (5 * 3), to the last (5 * 10) number, to get the complete table of the given numbers.

Different ways to generate the table program

Following are the various ways to generate the table program in the C programming language.

Using for loop
Using while loop
Using do-while loop
Using user-defined function
Using recursion function
Using if and goto statement
Using for loop and pointer
Using nested for loop

Program to generate the table of a given number using for loop

Let’s consider an example to print the table of the specific number using for loop in the C programming language.

Program1.c

  #include   int main()  {  int num, i; // declare a variable  printf (” Enter a number to generate the table in C: “);  scanf (” %d”, #); // take a positive number from the user    printf (“n Table of %d”, num);  // use for loop to iterate the number from 1 to 10  for ( i = 1; i <= 10; i++)  {  printf (“n %d * %d = %d”, num, i, (num*i));  }  return 0;  }  

Output

Enter a number to generate the table in C: 7   Table of 7   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

In the above code, for loop executes from 1 to 10, the given number is multiplied by 1, and the next iteration is multiplied by 2, and the process continues until it multiplies the number to 10. Finally, it prints the table on the screen.

Program to generate the table of a number using while loop

Let’s consider an example to print the table for a number using a while loop in the C programming language.

Program2.c

  #include   int main()  {  int num, i = 1; // declare a variable  printf (” Enter a number to generate the table in C: “);  scanf (” %d”, #); // take a positive number from the user    printf (“n Table of %d n “, num);    // use while loop to evaluate the condition  while (i <= 10)  {  // print the table  printf (” %d x %d = %d n”, num, i, (num * i));  i++; // incremented by 1   }  return 0;  }  

Output

Enter a number to generate the table in C: 8   Table of 8    8 x 1 = 8   8 x 2 = 16   8 x 3 = 24   8 x 4 = 32   8 x 5 = 40   8 x 6 = 48   8 x 7 = 56   8 x 8 = 64   8 x 9 = 72   8 x 10 = 80

Output

Enter a number to generate the table in C: 3   Table of 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

Output

Enter a number to get the table: 23   The multiplication table of 23   23 x 1 = 23   23 x 2 = 46   23 x 3 = 69   23 x 4 = 92   23 x 5 = 115   23 x 6 = 138   23 x 7 = 161   23 x 8 = 184   23 x 9 = 207   23 x 10 = 230

Output

  #include   int main ()  {  int n, i = 1; // declare variable  printf (” Enter a number to get the table: “);  scanf (” %d”, &n); // take a positive number   table:  // It is a label   // display table  printf (” %d * %d = %d n”, n, i, (n * i));  i++; // incremented by 1  /* if statement check the value of i should not be greater than 10. */  if ( i <= 10)  goto table; // use goto statement to jump to the table label   }
