Output and correction

Question

void printArray(int arr[5], int size) {
for(int x=0; x<size; x++) {
cout <<arr[x];
}
}

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

Answer 1

Arrays in C++ are enclosed in curly braces {}

printArray({1,2,3,4,5},5)

does not work however.
You need to specify the variable type beforehand like this:

int a[] = {1,2,3,4,5};
printArray(a,5);

Then it works.

You could also cchange write the function in different ways:

void printArray(int arr[], int size)

since you send the size anyway and brackets without the number allow arrays of any size

or also

void printArray(int* arr, int size)

which is basically the same (pointer to first array position)

I hope it helps :)

Answer 2

#include <iostream>
using namespace std;
void array(int a[],int size)
{
int i;
for(i=0;i<size;i++)
{
cout<<a[i]<<endl;
}
}

int main()
int a[]={1,2,3,4,5};
void array(a,5);
return 0;
}
