Sorry, there is a typo in my function definition. Mistakenly I have
specified number 10
in the for loop condition. It should be the variable how_many. The
corrected version
of print_repeat.

void print_repeat(char to_print, int how_many)
{
int i = 0;
 for(i=0;i<=how_many;i++)
printf("%c", to_print);

 printf("\n");
}
