Answer 1

Answers:
1. 4
2. 4

Explaination: 1st Question:

char value must be in single quotes and string value must be in double quotes.

Ex: char x = 'm';
string y = "Peter";

1st option is wrong because char value and string value are not like the example above

2nd option is wrong because string value is enclosed in single quotes it should be enclosed in double quotes

3rd option is wrong because we can't pass data types in arguments to a function.

4th option is correct.

Explaination: 2nd Question:

1st option is wrong because nameP variable was never declared in the main function

2nd option is wrong because sexP,nameP... were never declared in the main function

3rd option is wrong because int &ageP means it holds the address so we should pass a variable to function not the value i.e 30

4th option is correct because we are the passing the required variables age, name which were already declared in the main function as an arguments to

int &ageP and string &nameP to hold their addresses.
