How its works,please help me!

Question

#include <iostream>
using namespace std;

int main()
{
int myArr[4];
int x,y;
int total=0;

cin >> y;
for(int x=0; x<=3; x++) {
myArr[x] = y;

cout << x << ": " << myArr[x] << endl;
total = total + myArr[x];
cout << total;
}

return 0;
}
//inputs are 1
//outputs :
0 : 1
11 : 2
22 : 3
33 : 4
4

Answer 1

cin >> y; //taking input to y, ex: 1
for(int x=0; x<=3; x++) {
myArr[x] = y; //every array element, you are assigning y => 1

cout << x << ": " << myArr[x]<<" : " ;
total = total + myArr[x];
cout << total<<endl;

Here total is, sum of array elements, in each iteration, you are displaying...
X : myArr[x] : total
0 1 1
1 1 2
2 1 3
3 1 4

Check this by removing endl and add it after total as I given above... I think, You are confusing with that only,.
In your code total displaying in next line, with other results without a separating... So add spaces for clear understanding, results...

Answer 2

Where is your confusion in this program...?
Which part you not understanding...

Answer 3

Explain full programme, because the output of this code is confused me.
