3. Consider the C code below. int test(bool param) { char *pVar; bool bVar = param; if(bVar) { char buf(500); pVar = (char*)malloc(500 * sizeof(char)); } } int main(void) { test(true); return 0; } There are three variables (pVar, bVar, buf) and one parameter (param) used in the code. Which variables/parameters will be stored in the stack space? Which variables/parameters will be stored in the heap space? (10 pts)
