Answer:
The output is 1
Explanation:
Analysing the flow of program (We start from the main method)
The main begins here
int main (void)
{
This line declares a as integer and also initializes it to 2
int a = 2;
This line passes 2 to the function names toronto and also prints the result of the function
printf ("%d", toronto (a));
return (0); }
The toronto function begins here.
Note that the function receives 2 as its argument and this is saved in variable x
int toronto (int x)
{
This declares w as integer
int w;
If x is 0, w equals 1
if (x == 0) w = 1;
If otherwise
else
This reduces x by 1 and performs a recursion
w = toronto (x-1);
return (w);
}
Because of the structure of the if condition in the toronto function, the function will be repeated until x is 0.
And when x = 0; w = 1
This returns w (i.e. 1) back to the main function where 1 is printed as the output
return (w);
