LANGUAGE: JAVA
CHALLENGE:
Assume you are given an int variable named nPositive and a 2-dimensional array of ints that has been created and assigned to a2d. Write some statements that compute the number of all the elements in the entire 2-dimensional array that are greater than zero and assign the value to nPositive.
SOLUTION:
nPositive = 0; for (int i=0; i<a2d.length; i++) for (int j=0; j<a2d[i].length; j++) if (a2d[i][j] > 0) nPositive++;
nPositive = 0;
for (int i=0; i< a2d.length; i++){
for (int j=0; j 0)
nPositive++;
}
}
nPositive = 0;
for (int i = 0; i < a2d.length; i++)
{
for (int j = 0; j 0)
{
nPositive++;
}
}
}
nPositive = 0;
for (int i = 0; i < a2d.length; i++)
{
for (int j = 0; j 0)
{
nPositive++;
}
}
}
nPositive = 0;
for (int i = 0; i < a2d.length; i++)
{
for (int j = 0; j 0)
{
nPositive++;
}
}
}
nPositive = 0;
for (int i = 0; i < a2d.length; i++)
{
for (int j = 0; j 0)
{
nPositive++;
}
}
}
nPositive = 0;
for (int i = 0; i < a2d.length; i++)
for (int j = 0; j 0)
nPositive++;
try this one:
nPositive = 0;
for (int i=0; i<a2d.length; i++){
for (int j=0; j 0){
nPositive++;
}
}
}
nPositive = 0;
for (int i=0; i<a2d.length; i++){
for (int j=0; j 0){
nPositive++;
}
}
}
