Chapter 3, Problem 33RE
What is wrong with the following
System.out.print("Enter the number of quarters: ");
int quarters = in.nextInt();
if (in.hasNextInt())
{

Check out a sample textbook solutionStudents have asked these similar questions
int stop = 6;
int num =6;
int count=0;
for(int i = stop; i >0; i-=2)
{
num += i;
count++;
}
System.out.println("num = "+ num);
System.out.println("count = "+ count);
}
}
1. a.
Are Count and sum the same? yes or no, why?
{
int sum = 0;
for ( int count = 0; count < 10; count++ )
{
System.out.print( count + " " );
sum = sum+count;
}
}
b.
{
int sum = 0;
for ( int count = 0; count < 10; count++ )
{
System.out.print( count + " " );
sum = sum+count;
}
System.out.println("\nAfter the loop count is: " + count );
}
c. What is printed, why?
class FindIt
{
private int sum;
public FindIt( int sum )
{
this.sum = sum;
}
public void increment( int inc )
{
sum = sum + inc;
System.out.println("FindIt sum: " + sum );
}
}
public class MainClass
{
public static void main ( String[] args)
{
int sum = 99;
FindIt findObj = new FindIt( 34 );
findObj.increment( 6 );
System.out.println("sum: " + sum );
}
}
Please find the running time of the program below. See attached photo for example.
int exam_1(int n) { int i, j, k, sum = 0; for(i=3; i<=n * 3; i+=3) { for(j=1; j<=n; j++) { for(k=2; k<=j; k* =2) { sum = sum + k * i; if(sum > j) { sum = sum + 1; } } } }}
