arrays with and without zeros

In this article, we show two programs. In the first program, the array is not initialized. In the second program it is initialized to a value 0.

#include<iostream>
using namespace std;
int main(){
	const int size = 10;
	int a[10];
	cout<<"The elements are "<<endl;
	for(int i=0;i<size;i++){
		cout<<a[i]<<endl;
	}
	return 0;
}

The output of the above program gives garbage values.

In the second program,one value is initialized to 0 and hence all the values are 0.

#include<iostream>
using namespace std;
int main(){
	const int size = 10;
	int a[10]={0};
	cout<<"The elements are "<<endl;
	for(int i=0;i<size;i++){
		cout<<a[i]<<endl;
	}
	return 0;
}
