terminating a loop with the newline key.

[Nyah Check]

hey guys i have written a loop that stores numbers in an array and stops when the '\n' key is pressed but this doesnot terminate the loop up to the end of the array.

#define MAX 10
int n, m;


//CODE FRACTMENT.


for( int i = 0; i < MAX && n != '\n'; i++)
   n= scanf(" %d", array[i];
   m = getchar();

i dont understand why this doesnt work.

sorry for the error in the code

here is the correct version.

for ( int i = 0; i < MAX && m != '\n'; i++)
   n = scanf(" %d", array[i];
   m = getchar();

//this loop doesnt exit after you enter 3 numbers and press '\n'

The code indented right; does this help you understand?

for ( int i = 0; i < MAX && m != '\n'; i++)
   n = scanf(" %d", array[i];
m = getchar();

It would be nice if you posted something which you at least tried to compile, then we wouldn't have to guess which of the many syntax errors are actually irrelevant to your question.

ok i looked at the loop and thought this may be where the problem came from. However @stahta01 thanks for the tip i'll implement that and see what happens.
@Salem i would check for the complete code and paste for us to see what it gives....do that later....

I DID NOT CHANGE YOUR CODE; I just indent what code you posted!!!!

Indentation DOES NOT change how the code runs in C!

ok so what other thing can i do to ensure the loop exits after pressing the '\n' key

[stahta01]

Read these links
If Statements in C - Cprogramming.com
scanf - C++ Reference

Then ask a real question about what you wish to do.
Post code that compiles and shows the problem.

Note: I have NO idea why you think you need a for loop instead of a while loop.

Edit: I would use fgets and sscanf; but, I am just guessing at what you are trying to do.
(Likely use strchr with them to do what I am guessing you are trying to do. http://www.cplusplus.com/reference/c...string/strchr/)

The value of m never changes in your loop; how do you think it will ever end because a '\n' is read?

You should probably be using a do-while loop if you want to terminate based on a certain input:

do {
    /* stuff */
} while (getchar() != '\n');
