Question 1
Write function headers for the functions described below:
(i) The function check has two parameters. The first parameter should be an
integer number and thesecond parameter a floating point number. The function
returns no value.
(ii) The function mult has two floating point numbers as parameters and
returns the result ofmultiplying them.
(iii) The function time inputs seconds, minutes and hours and returns them
as parameters to itscalling function.
(iv) The function countChar returns the number of occurrences of a character in a string, both
provided as
parameters.
(i) The function check has two parameters: an integer and a floating point number, and it returns no
value.
def check(integer_param: int, float_param: float) -> None:
pass
(ii) The function mult has two floating point numbers as parameters and returns their product.
def mult(float_param1: float, float_param2: float) -> float:
pass
(iii) The function time takes seconds, minutes, and hours as inputs and returns them to the calling
function.
def time(seconds: int, minutes: int, hours: int) -> (int, int, int):
pass
(iv) The function countChar returns the number of occurrences of a character in a string, both
provided as parameters.
def countChar(input_string: str, character: str) -> int:
pass

, endl; int function2()
{
cout << "Inside function function1 " << endl;
}
}
(ii) int sum(int x, int y)
{
int result;
result = x +
y;
}
(iii) int computeProd(int n)
{
if (n == 0)
return 0;
else
}
n * computeProd(n – 1);
(iv) void aFunction(float a)
{
float a;
cout << a << endl;
}
(v) void theProduct()
{
int
a;
int
b;
int
c;
int result;
cout << “Enter three integers “ <<
endl; cin >> a >> b >> c;
result = a * b * c;
cout << “Result is “ << result <<
endl; return result;
}
