How to arrange the outputs of an array in ascending order using C++

Question

Hi I'm new to programming and currently stuck at trying to get the output of the program to show in ascending order ,

int foo[10];

 for (int i=0; i<=10; i++)

 {

 cout<<"Please enter a number: "<<endl;

 cin foo[];

 }

I'm stuck at trying to make it display in ascending order, I tried different methods but to my luck fails me I've seen tons of examples for this question but unfortunately for me I'm only limited to answering this in C++ please can anyone help.

Answer 1

If your assignment allows you to use standard algorithms, then it's simply

std::sort(std::begin(foo), std::end(foo));

followed by a loop to print them.

If the object of the exercise is to write your own sorting algorithm, then you should research them yourself .

Answer 2

Firstly, you should run your for (int i = 0; i < 10; i++) instead of for (int i = 0; i <= 10; i++) , because the array has 0-9 indexes, rather than 0-10. Secondly, the syntax for cin foo[] is cin >> foo[i]; in this case.

For the sort, you could look into std::sort, or you could look into some sorts yourself, I would recommend starting with bubble sort, selection sort or insertion sort, as they are the easiest ones to implement.
