Answer:
int sum = 0;for(int[] m : arr2){ for(int n : m) { sum += n; }}
Explanation:
Option A is wrong because it will throw an ArrayIndexOutOfBoundsException during the last iteration of the first and second loop.
the number of accessible element in the first dimension of arr2 is from 0 to arr2.length-1 but the loop specify 0 to arr2.length which will be the first cause of the error
while that of the second dimension specify 0 to arr2[j].length instead of 0 to arr2[j].length-1
Option B is also wrong because the expression j-- will decrement the value of j instead of incrementing it and the second dimension specify 0 to arr2[j].length instead of 0 to arr2[j].length-1 which will also cause an ArrayIndexOutOfBoundsException.
Option C will successfully calculates the sum of all elements arr2.
Answer:
C) tracert
Explanation:
Based on the information provided in the question with regards to the situation at hand, It can be said that the best TCP/IP utility to use to troubleshoot this would be a tracert. In the context of information technology and networking, this is a utility used in order to see and measure the transit route that your information is taking making it easy to detect any problems over the network between two systems, such as delays or drops in packets.
You can easily find and changed the data by using lookup table. You can also find the data within few seconds.
A source can be either primary or secondary. The statement that if you interview a dentist to learn about her experiences on the job, she is considered a secondary source of information is false. A primary source provides direct or firsthand experience, while a secondary source of information describes or analyzes the primary source. In this case, when the dentist is interviewed she is considered as primary source because she is speaking about herself and her experience.
