C Program to Print Multiplication Table

The C program to print the multiplication table from 1 x 1 to 12 x 10 as shown below is given example C code.

This C program contains two do…. while loops in nested form. The outer loop is controlled by the variable row and executed 12 times. The inner loop is controlled by the variable column and is executed 10 times, each time the outer loop is executed. That is, the inner loop is executed total of 120 times, each time printing a value in the table.

C program to print the multiplication table

#define COLMAX 10
#define ROWMAX 12
main()
{
   int row,column, y;
   row = 1;
   printf(" MULTIPLICATION TABLE \n");
   printf("-----------------------------------------\n");
do /*......OUTER LOOP BEGINS........*/
   {
    column = 1;
do /*.......INNER LOOP BEGINS.......*/
{
    y = row * column;
   printf("%4d", y);
    column = column + 1;
}
   while (column <= COLMAX); /*... INNER LOOP ENDS ...*/
   printf("\n");
   row = row + 1;
}
      while (row <= ROWMAX);/*..... OUTER LOOP ENDS .....*/
      printf("-----------------------------------------\n");
}

Ouput

                MULTIPLICATION TABLE

Let me know if you find any difficulty in understanding this C Program with example and I would be glad to explain it further.
