C | Storage Classes and Type Qualifiers | Question 11
Consider the following C function
int f(int n) { static int i = 1; if (n >= 5) return n; n = n+i; i++; return f(n); } |
The value returned by f(1) is (GATE CS 2004)
(A) 5
(B) 6
(C) 7
(D) 8
Answer: (C)
Explanation: Since i is static, first line of f() is executed only once.
Execution of f(1)
i = 1
n = 2
i = 2
Call f(2)
i = 2
n = 4
i = 3
Call f(4)
i = 3
n = 7
i = 4
Call f(7)
since n >= 5 return n(7)
