Unable to understand this!

Question

int [ ] myArr = {6, 42, 3, 7}; int sum=0; for(int x=0; x<myArr.length; x++) { sum += myArr[x];

Answer 1

This section below creates an integer array object with four elements inside which are 6, 42, 3, 7 respectively.

int [ ] myArr = {6, 42, 3, 7};

This section below declares an integer variable with an initial value of zero but will change by the end of the for loop.

int sum=0;// total sum of all numbers will be stored here

This section below traverses through the array collection and adding each individual element to the "sum" variable above.

for(int x=0; x<myArr.length; x++) {
sum += myArr[x];
}

Finally, if you still don't understand it then I recommend codingbat website ( a lot of exercises to get you going ), reading relevant books, get involved in programming communities. STUDY, PRACTISE AND PERSISTENCE!

HAPPY CODING!.

Answer 2

int [ ] myArr = {6, 42, 3, 7};//Array
int sum=0;// Sum
for(int x=0; x<myArr.length; x++)
{ sum += myArr[x];}// sum = 0 + 6, sum = 6 +42, sum = 48 +3 ...
