Interpreter errors handing STL objects in functions

[koziscool]

Eg, this code:

void Eratosthenes(vector<long int>* primes, long int limit){
    vector<bool> primeArray(limit, true);
    for( long int p = 2; p < sqrt(limit); p++){
        if( primeArray[p]){
            for(long int m = p*p; m < limit; m += 2 * p)
                primeArray[m] = false;
        }
    }

    primes->push_back(2);
    for( long int j = 3; j < limit; j ++ 2 ){
        if (primeArray[j])
            primes->push_back(j);
    }
}

produces this error:

input_line_9:10:42: error: expected ')'
    for( long int j = 3; j < limit; j ++ 2 ){
                                         ^
input_line_9:10:8: note: to match this '('
    for( long int j = 3; j < limit; j ++ 2 ){
       ^

Interpreter Error: 

Btw, that code seems to run just fine on gcc.

This code has a basic typo in it, the interpreter runs it fine (when edited correctly). Should I delete this, or leave it here in case I reproduce a similar error?

[koziscool]

Ok so here might be a better example, that's not a typo

long int e10(vector<long int>* primes, int limit){
    long int total = 0;
    vector<long int>::iterator: i = primes->begin();
    while( *i < limit ){
        total += *i;
        i++;
    } 
    return total;
}

Here the interpreter says:

input_line_14:2:51: error: function definition is not allowed here
 long int e10(vector<long int>* primes, int limit){
                                                  ^

Interpreter Error: 

again runs fine on gcc

The same example should work with xeus-cpp (https://github.com/compiler-research/xeus-cpp)

Acutally xeus-cpp also offers xeus-cpp-lite (xeus-cpp in jupyterlite which is a jupyterlab distribution that works completely inbrowser)

You can try the above example here https://compiler-research.github.io/xeus-cpp/lab/index.html
