C++ number of elements in array

Question

Problem:

Hello All,

I am a new student in C++ programming. I started learning programming out of my own curiosity. One of my friends told me that C++ is easy to pick up and I stick on his words. I am helping my friends’ and different websites help to learn new things every day. Today, I have got a new problem to solve. The problem is asking me to find all the number of elements in an array. Let say, I have an array of

int array [] = {1,2,3,4,5,6,7,8,9,10};

The program should count all the elements and print the result 10 as there are ten elements in my array.

How can I solve this problem? I am looking forward to having a solution from you. Thanks for your help, guys.

Hello Gavin,

You’ve asked a nice but entry question. Basically, you want to find out the array length/size. We can solve the problem in a couple of ways. I am trying to keep it as simple as possible. I hope this might help you more. Please, find the code snippet below and reply to this thread if you still got any confusion.

#include <iostream>
using namespace std;
int main(){
    int array[] = {1,2,3,4,5,6,7,8,9,10};
    int array_count=0;
    for(int i=0;i<10;i++){
        if(array[i]!='\0')
            array_count++;
    }
    cout<<"Total elements in this array are: "<<array_count;
}

And the program will produce an output

Total elements in this array are: 10

Thanks
