This is not really that I can't do the exercise, I am very close to doing it, but something is wrong.

Is this copied from the book?
Controversially, I don't have it.
frozen badger
so this is from the book, I only did a slight update to square2.c to bbetter understand it, I changed the n to entries, let me send it
square.2:
/* Prints a table of squares using a for statement */
#include <stdio.h>
int main(void)
{
int i = 0, n = 0;
printf("This program prints a table of squares. \n") ;
printf("Enter number of entries in table: ");
scanf("%d", &n);
for (i = 1; i <= n; i++)
{
printf("%10d%10d\n", i, i * i) ;
}
return 0;
}
@frozen badger
frozen badger
this is the original square2.c from the book
wait
I wanted to add debugging
uh
...
printf("You shall not pass \n");
while( ((action = getchar()) == '\n') )
{
printf("Ok \n");
continue;
}
...
Now the output is:
You shall not pass
Ok
Ok
Ok
Ok
Ok
Ok
Ok
Ok
why can't it
OHHH
wait no
oh
i got it

Do debugging using a real debugger, then.
Adding code for the purpose of debugging is cursed really.
I'd forgive the odd printf(), but really... a debugger is the best tool for what you need.
frozen badger
well I got it
just in case anybody in the thread needs to look
// Modify the square2 . c program of Section 6.3 so that it pauses after every 24 squares and
// displays the following message:
// Press Enter to continue...
// After displaying the message, the program should use getchar to read a character,
// getchar won’t allow the program to continue until the user presses the Enter key.
/* Prints a table of squares using a for statement */
#include <stdio.h>
void clear_i_buffer(void);
int main(void)
{
int i = 0, entries = 0;
int max_entries = 24;
char action = '!';
printf("This program prints a table of squares. \n") ;
printf("Enter number of entries in table: ");
scanf("%d", &entries);
clear_i_buffer();
for (i = 1; i <= entries; i++)
{
if(i >= max_entries)
{
printf("You shall not pass \n");
while( ((action = getchar()) == '\n') )
{
printf("Ok \n");
max_entries += 24;
break;
}
}else{
printf("%10d%10d\n", i, i * i) ;
}
}
return 0;
}
void clear_i_buffer(void)
{
while ((getchar()) != '\n');

@frozen badger how is the book. Is it good ?

<@715197403703148595> how is the book. Is it good ?
woeful radish
for a person who is not a beginner nor a intermediate either ?
frozen badger
like
i used to watch a C programming video before, from which I couldn't even make a tic tac toe but I did learn something
then I found this book, but I skipped so many chapters for youtube video's again
now I am just only using this book to learn
yea
it's good
woeful radish
oki, it's just that I just finished another beginner C book. And on a dilema whether I should read K&N one too. Because I am shit at memory. btw I just made tic-tac-toe 3 days ago. : P
