Hello, please EXPLAIN how you got your answer. Thank you!
int x = 1
int j;
for (j=0; j <=2 ; j++)
x = x * j ;
cout << x << endl;
What is the output of the C++ code above?
Answer:
A) 0
B) 1
C) 2
D) 3
int x = 1; // x is initialized to 1 int j; for (j=0; j <=2; j++) // here this for loop iterates 3 times. for j=0, j=1,j=2 x = x * j; // let's see what happens with the above for loop // j=0 // x = x*j = x*0 = 0 // j=1 // x = x*j = 0*1 = 0 // j=2 // x = x*j = 0*2 = 0 // so, after the loop, value of x is 0 cout << x << endl; // prints 0 Output: 0
