SYSTEM LEVEL PROGRAMMING

1.Read the following two code fragments, func1(x) and func2(x) . Do func1(x) and func2(x) have same behavior in any circumstances? Give an example of f(int) to show that func1(x) and func2(x) have the same behavior. If their behaviors are not same in some cases, give another example of f(int). Explain how these cases affect compilation in program performance optimization?

int f(int);

int func1(x) {

return f(x) + f(x) + f(x) + f(x);

}

int func2(x) {

return 4*f(x);

}
