Is it possible to pass the int variable b to the longlong parameter b in function1? The specific code is as follows:

void function1 (long long b)
{

........

}

main(){

int a;

a=100;

function1(a);

}

I don't even understand these lines of code.

Remember to pass by reference when passing Integer as a parameter

This is OK. There is no problem passing int as a function parameter to a long long type parameter.

Yes, you just need to know whether you can lose it or not.

You can pass an int value to a function whose parameter type is defined as long long, and the compiler will perform type promotion.

It is equivalent to converting the type for you, so it is possible, but it is not recommended to use it in this way because you will get confused.

Yes, there is no problem with passing it as a parameter.
