array boundaries

conditional statements, if, nested , "C++ interprets positive numbers as true and negative numbers as false" Wrong!

game logic problem with memory. Suppose you have a game where the monster population fluctates, and you constantly want to minimize the amount of memory your program is using. Which technique do you use? Dynamic memory

Code analysis, how many times the loop executes

for (int i = 1; x > 0; ) { switch( x ) { case 1: x++; break: case 2: x *= x; break; case 3: x += x; break; case 4: x = -1; break; default: x=0; } }

Code analysis with while

int x = 2; while ( x < 7 ) { x++; if (x == 4 ) x =7; else x += 2; }

Legal function declaration

Code analysis undefined behavior compounded operation int x; x+= 3;

Code analysis, variable scope in functions

Arrays and pointer arithmetic

Code analysis, statement about errors in a program (memory leak for instance)

Code analysis, sizeof operator applied on arrays

Code analysis, describe algorithm of a function (copying array, comparing array, etc)

Code analysis, simple loop program and result of arithmetic problems

C++ operation (ternary operation, extration, insertion, etc)

Code analysis, legal code? const pointer, const pointer to const variable

True or False, function signature, you can overload a function by differing the return type? NO

random numbers and ranges [-17, 6]

Code analysis, undefined behavior

Code analysis, output of a program with undefined behavior on cout

Code analysis, memory leak?

continue, break, return instruction inside loops

Code analysis, function by reference

Code analysis, arrays const char* s[4] = { {"abcd"},... };

Code analysis, unary operator and cout. the output of the following program is "x: 10, i: 11"

int main() { int x, i; i = 10; x = i++; std::cout << "x: " << x; std::cout << "i: " << i << std::endl; return 0; }

Code analysis, boolean expression evaluation
