Please explain the dry run of else statement

#1

I m not getting how the even row has printed. In the true expression of while loop we have (col<=row-2) so how 1001 will get printed if row=4

#2

@Tanvi-Varshney-250726472940778

col = 1;
cout << "1"; //this will print "1"
while (col <= row-2) {
    cout << "0";
    col = col + 1;
}   //this loop will run "row-2", ie "2" times 
// so now the output is "100"
cout << "1"; // this will print the last 1, making the output "1001"
