Thread: Not sure where the mistake is coming from?

Copied exactly from the book:

Code:

#include<iostream>
#include<iomanip>
#include<array>
using namespace std;


int main(){
    
    const size_t responseSize{20};
    const size_t frequencySize{6};
    
    const array<unsigned int, responseSize> responses{1, 2, 5, 4, 3, 5, 2, 1, 3, 1, 4, 3,3, 3, 2,3, 3, 2,2, 5};
    
    array<unsigned int, frequencySize> frequency{};
    
    for (size_t answer{0}; answer < responses.size(); ++answer){
        ++frequency[responses[answer]];
    }
    
    cout << "Rating"  << setw(12)  << "Frequency"  << endl;
    
    for (size_t rating {1}; rating < frequency.size(); ++rating){
        cout << setw(6)  << rating  << sets(12)  << frequency[rating]  << endl;
    }
    
}

Says setw is not given a value or something. As you can see...

I can't tell because I reconfigured codeblocks without knowing what I exactly did. Meaning the error box is gone and I can't put it back where it used to be.

Tim S.

Yes, I did a brief google search and had logs unchecked.

Yes.

still didn't work.

Thank you, I figured it out. { wrong bracket it was meant to be a (

Don't just say "still didn't work" without providing such an update, otherwise I'll just retort "then fix it!"

No, baby please! I found the error and I fixed it and now the code is working the way it should.

Code:

#include<iostream>
#include<iomanip>
#include<array>
using namespace std;


int main(){


    const size_t responseSize{20};
    const size_t frequencySize{6};


    const array<unsigned int, responseSize> responses{1, 2, 5, 4, 3, 5, 2, 1, 3, 1, 4, 3,3, 3, 2,3, 3, 2,2, 5};


    array<unsigned int, frequencySize> frequency{};


    for (size_t answer{0}; answer < responses.size(); ++answer){
        ++frequency[responses[answer]];
    }


    cout << "Rating"  << setw(12)  << "Frequency"  << endl;


    for (size_t rating {1}; rating < frequency.size(); ++rating){
        cout << setw(6)  << rating  << setw(12)  << frequency[rating]  << endl;
    }


}
