java - Variable repeat error? -


why getting compile-time error in following code?

private static void phi(int n){     if(n > 1000)         for(int = 3; <= n; += 2)             //do     else         for(int = 35; <= n; += 90)             //do }

the error says

java:22: error: variable i defined in method phi(int)

but according me, @ scenario, either if statement or else statement executed, never both executed @ same time.

is loophole in java's compilation techniques or method wrong?

edit 2

brackets seem have fixed problem. lot blackbelt.

edit 1

double parenthesis doesn't seem reason still error after removing parenthesis. in fact double parenthesis got added mistake.

there more 1 line after if , before else, have use braces desired behaviour, not necessary in for statement, mandatory in if in case.

also, @joseph82 pointed... there ( in first if!

private static void phi(int n){     if(n > 1000) {         for(int = 3; <= n; += 2)             //do     } else {         for(int = 35; <= n; += 90)             //do     } }

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
