Question
How many times does the statement execute in the following code?for(int n = 0; n < 7; n++){ for(int m = 0; m < 7;m++){ statement; }}
Solution
The statement in the nested loop will execute 49 times. Here's why:
- The outer loop runs 7 times because it starts at 0 and ends when n is less than 7.
- For each iteration of the outer loop, the inner loop also runs 7 times because it starts at 0 and ends when m is less than 7.
- Since the inner loop runs 7 times for each iteration of the outer loop, the statement will execute 7 (from the outer loop) * 7 (from the inner loop) = 49 times in total.
