Code is written in C.

I know the output is

Test 4 is at the beginning

Test 3 is at the beginning

Test 2 is at the beginning

Test 1 is at the beginning

Test 2 is at the end

Test 3 is at the end

Test 4 is at the end

The result of this function call is 60.

Im having a hard time following how this output is determined.

2. What does the following program print? (15 points) # include int prod(int number); int main(void) int x = 4; printf("The result of this function call is %din",prod(x)); return 0; int prod(int number) int printf("test %d at the beginningin", number); if(number== 1) return 1 p (number +1)* prod(number 1); printf("test %d at the endin', number); return p
