Given: for(i = 0 ; i < 4 ; i++)
for(j = 1 ; j < 4 ; j++)
……………
Statement
……………
How many times the above nested loop will iterate?
- 12 times
- 8 times
- 4 times
- 16 times
Answer
12 times
Reason — The outer loop will execute 4 times. For each iteration of outer loop, the inner loop will execute 3 times. Therefore, total iterations of nested loop will be 4 x 3 = 12 times. The below table summarizes the iteration of nested loops:
| Value of i | Value of j |
|---|---|
| 0 | 1 |
| 2 | |
| 3 | |
| 1 | 1 |
| 2 | |
| 3 | |
| 2 | 1 |
| 2 | |
| 3 | |
| 3 | 1 |
| 2 | |
| 3 |
