how to find length of integer array

[pavan146]

plz tl me how to find length of integer array

[wingless]

int x[5];
Length is: sizeof(x)/sizeof(int);

[crazyboy]

using

len = array.length( );

functionnn

[necrolin]

using

len = array.length( );

functionnn

Correct me if I'm wrong, but length() works for strings not integer arrays. If it does work then please demonstrate how, because I got a syntax error trying it.

Here's some code that I know works. It shows 2 ways of getting the length. Wingless' answer is correct as shown bellow.

#include <iostream>
#include <cstdlib>

using namespace std;

int main()
{
    int myArray[] = { 1, 2, 3, 4, 5};

    int length1 = sizeof myArray / sizeof *myArray;
    int length2 = sizeof myArray / sizeof(int);

    cout << length1 << endl;
    cout << length2 << endl;

    return EXIT_SUCCESS;
}

As Crazyboy says, use the following:

string str (ARRAYNAME);
SomeLengthVar=str.length();

or simply use:

strlen(ARRAYNAME));

That's about the easiest way

You're so right, that's why I used:

string str (ARRAYNAME);
      SomeLengthVar=str.length();

In my example, the string str (ArrayName), makes a string called str, of the array, and then feeds that to the ".length()"

Did you read the question? He's asking for how to get the length of an integer array, not a string.:P strlen(MyIntArray) is just so not going to do what the poster wants.

[kri_prasad2000]

int a[] = {1,2,3,4,5,6};
int n = sizeof(a) / sizeof(a[0]); //returns Size of the array

I did read the question, however it seems like my brain failed, since I was thinking about it as a char array >.<'.

But if it's a integar array, then the right way to do it, is ofc. to do the:

(sizeof myArray / sizeof *myArray);

And I'm sorry for the confusion I made
