Description
1. The CandyBar structure contains three members.The first member holds the brand name of a candy bar.The second member holds the weight (which may have a fractional part) of the candy bar, and the third member holds the number of calories (an integer value) in the candy bar.
“` cpp
struct CandyBar{
char brand[30];
double weight;
int calorie;
}
“`
Write the following functions:
+ `void set(CandyBar & cb)`, that should ask the user to enter each of the preceding items of information to set the corresponding members of the structure.
+ `void set(CandyBar* const cb)` ,that is a overloading function .
+ `void show(const CandyBar & cb)`,that displays the contents of the structure.
+ `void show(const CandyBar* cb)`,that is a overloading function .
Write a simple program that uses these four functions.
A sample run might look like this:.
“` log
Call the set function of passing by pointer:
Enter brand name of a Candty bar: Millennium Munch
Enter weight of the candy bar: 2.85
Enter calories (an integer value) in the candy bar: 350
Call the show function of Passing by pointer:
Brand: Millennium Munch
Weight: 2.85
calories: 350
Call the set function of passing by reference:
Enter brand name of a Candty bar: Millennium Munch
Enter weight of the candy bar: 3.85
Enter calories (an integer value) in the candy bar: 361
Call the show function of Passing by reference:
Brand: Millennium Munch
Weight: 3.85
“`
2. Write a template function max5() that takes as its argument an array of five items of type T and returns the largest item in the array.(Because the size is fixed,it can be hardcoded into the loop instead of being passed as an rgument). Test it in a program that uses the function with an array of five int value({1, 2, 3, 4 ,5}) and an array of five double values{1.1, 2.0, 3.0, 4.0, 5.5}.
A sample run might look like this:.
“` log
Max int = 5
Max double = 5.1
