Default values for function are need to be specified from left to right only.
a. True
b. False
Answer:
b. False
Explanation:
Default values need to be specified from Right to Left order.
Example:
void calculate(int amt, int years, float rate=7.8); //valid
void calculate(int amt, int years=5, float rate=7.8); //valid
void calculate(int amt=21000, int years, float rate=7.8); //Invalid
Third statement is invalid as we skipped second parameter of the function. Rule says that default values should be set from Right to Left order only. We cannot provide a default value to specific parameter in the middle of an parameter list.
