Consider the following program in C:#include <stdio.h> void func(int i, int j) { if(i < j) { int i = 0; while (i < 10) { j += 2; i++; } } printf("%d", i); } int main() { int i = 9, j = 10; func(i, j); return 0; }The output of the program is ________. (answer in integer) Note: Assume that the program compiles and runs successfully.

Let us trace the execution of the program step-by-step:

1. In main(), local variables i = 9 and j = 10 are initialized, and func(9, 10) is called by value.

2. In func(int i, int j), the formal parameters are initialized as $i = 9$ and $j = 10$.

3. The condition if (i < j) evaluates to 9 < 10, which is true.

4. Inside the if block, a new block-scoped variable int i = 0; is declared. This variable shadows the outer parameter i throughout the inner block.

5. The while loop iterates and increments the block-scoped i until it reaches 10.

6. After the if block terminates, the inner i goes out of scope.

7. The statement printf("%d", i); accesses the outer parameter i, whose value remains unchanged at 9.

Therefore, the program outputs 9.
