arrays

[elhamalz]

how can I Create an integer array c that holds the element-wise product of the two arrays?

#include <iostream>
using namespace std;
int main()
{
    int a [52]={0,1,2,3,4,5};
    int b [52]={0,1,2,3,4,5};
    int c [];
            
}

The c that you have now has no elements. You have to state the size right there.

I presume that you don't expect:
std::transform( std::begin(a), std::end(a), std::begin(b), std::begin(c), std::multiplies<int>() );

#include <iostream>
using namespace std;
int main()
{
    int a [52]={0,1,2,3,4,5};
    int b [52]={0,1,2,3,4,5};
    int c [52];
            
}

so how would I multiply each member of a with b ( 0*0 , 1*1 ... ) in array c?

If you had looked up the reference documentation for transform, you would have two hints. Perhaps for is an easier hint?

Thank you! But I've solved it and I have put a check on the thread!

Thank you again
