Here, you have defined memory inside the function, and somewhere else you have to release it, which can icrease the possibility of error if the programer forgets that.
It is a good habit to define and release the memory in the same place. You could feed the resptr as the second argument to the function:
int bhmac(char *data, char **resptr)
{
char *res = 0;
res=(char*)malloc(...);
if (!res)
return 1; // error in allocation
*resptr = res;
..
return 0;
}
And in the place you call this function:
char *resptr = 0;
if (bhmac(data, &resptr))
return 1; // error
...
if (resptr)
free(resptr);
resptr = 0;

Is there some way to tell c++ to NOT include stdlib?
-nostdlib https://gcc.gnu.org/onlinedocs/gcc/Link-Options.html
Artöm
Which is explicitly stated in this link. He wants a strange thing, gonna try hard
Serenity
Hey
Serenity
Write a function that gets a matrix reference and reads the input to the matrix from the
user. If the input is non-zero replace it by 1. If the user did not enter enough values
before the end of the line, the remaining cells in the matrix will be populated with zeros.
Also make sure if the user inputs too many characters, you only take what's needed and
discard the remaining input. (Eg: 1509 is a 2x2 matrix with values 1101, and ‘1 5 ‘ is also
a 2x2 matrix with values 1111, the highlighted whitespace is taken as a 1 as discussed
above.)
Function signature:
Serenity
I wrote a function that works fine under 25 elements, but as I enter more than this value , it leaks into the second function call.
Serenity
int i, j = 0;
char x;
int flag = 0;
for (i = 0; i < SIZE; i++)
{
for (j = 0; j < SIZE; j++)
{
x=getchar();
if (x == '0')
mat[i][j] = 0;
else if (x == '\n')
{
flag = 1;
break;
}
else
mat[i][j] = 1;
}
if (flag == 1)
break;
}

Madhu It is why I was talking about yesterday..
Serenity
I can't implement a stopping condition.
Serenity
Yes now I have the instructions in front me fortunately
Serenity
I can't think of any idea how to solve it.
Serenity
I placed a condition outside the nested loops and it hasn't worked either..
Serenity
Do you mean using fgets ?
Serenity
Isn't it possible to do it this way with a little addition ?
Serenity
What will happen if I define a 25 chars long string by fgets and the user inserts more ? would the excessive values be ignored then ?

Sûre.. It stops after thé 24 space allocated
Serenity
Okay I'll give it a try. I've been instructed to this quite differently but what you suggested had been my initial idea..
Serenity
I may not use the string standard library
Serenity
But okay I get what you said
Serenity
but if you have an idea how to change my code to meet the requirements , let me know as well.
Serenity
that is what I have done and it has not worked
Serenity
Ok.
Serenity
How can I discard them ? How to make them not slip into the second matrix ?
Serenity
And what does it even happen ? Is it related to getchar() functionality ?
Serenity
Thanks a lot ! I got my logical mistake, and I'll try the second way you suggested which seems to be a little more efficient.

Hi guys! how to set the char * value in a class from one method for different fields in c++
Anonymous
for example i have
class Advertising {
private:
char * advertising_name;
char * client_name;
how to set advertising_name and client_name from one method
Zel
klimi
some function (params):
advertising = some param
client = some param
end

thanks

x > y is not the same as y <= x .
Zel
I disagree, but Im not gonna aurgue over it.
Harsh
I answered accordingly :)
Harsh
Oh true
Harsh
I'm sorry
Dima
lol
Harsh
I surely won't put someone down next time
Sorry
Zel
That was fast

If x=5 and y=3, these are the outputs:
A: x is the greater.
B: x is not the greater.

actually you are wrong. the question inverted three things 1) the operator, 2) the strings, 3) the variables. if they did only 1 and 2 the answer would have been same.
Zel
Dont worry about it. :3
