- Given the following class,

Given the following class,
class summation{
int num;
long sum; //summation of num
public:
void set_sum(int n);
void show_sum () {
cout <}
};
void summation::set _sum(int n)
{
int i;
num = n;
sum = 0;
for(i=1; i<=n; i++)
sum += i;
}
a) create a C++ function called make_sum() that returns an object of type summation. Have this function prompt the user for a number and then construct an object having this value and return it to the calling procedure.Demonstrate that the function works.
b)The function set_sum() was not defined in line within the summation class declaration. Give a reason why this might be necessary for some compilers.

Most C++ compilers supply nonstandard functions that allow cursor positioning and the like. If a compiler supplies such functions, create a function called myclreol() using C++ language a function that clears the line from the current cursor position to the end of the line. However, give this function a parameter that specifies the number of character position to clear. If the parameter is not specified, automatically clear the entire line. Otherwise, clear only the number of character positions specified by the parameter.

In the C++ standard library is the function strtol(), which has this prototype:
long strtol|(const char*start, const **end, int base);
The function cnverts the numeric string pointed to by start into a long integer. The number base of the numeric string is specified by base. Upon return, end points to the character in the string immediately following the end of the number. The long integer equivalent of the numeric string is returned. base must be in the range 2 to 38. However, most commonly, base 10 is used.
Create a function called mystrtol() that works the same as strtol() except that base is given the default argument of 10. Demonstrate that your version works correctly.
