Question

Design and implement a program thatdoes the following. Design your modules (functions) so thateach is about 3 to 15 lines of code after implementation. Make sure that you can express the purpose of each module(function) in one or two sentences.

a.     Gives the user a choice of determiningwhether a supplied positive integer number is a perfect number orof determining and printing all perfect numbers in a range oflow through high, where low andhigh are positive integers such that low <=high. A positive integer is a perfect number if it isequal to the sum of all its factors, including one but excludingitself. For example, 6 is a perfect number, since 6 = 1 + 2 +3, and 1, 2, and 3 are factors of 6.

b.     If the user wants to determine whether asupplied number is a perfect number, the program reads an integer,verifies that it is positive, and determines and prints whether itis a perfect number.

c.      If the user wants to determine allperfect numbers in a range, the program reads values forlow and high, verifies that they are positive andthat low <= high, and then determines and prints allperfect numbers in the range.

d.     Executes the program in a loop until theuser wants to stop.

Explanation / Answer

please rate - thanks #include #include int menu(); int input1(); void input2(int *,int *); int perfect(int); int main() {int num1,num2,choice=0,yes,count=0;      while(choice!=3)         {choice=menu();         switch(choice)         {case 1:num1=input1();                 yes=perfect(num1);                 if(yes==1)                     printf("%d perfect ",num1);                  else                      printf("%d not perfect ",num1);                 break;          case 2:input2(&num1,&num2);          printf("Theperfect numbers between %d and %d are: ",num1,num2);                 do                  {                  yes=perfect(num1);                  if(yes==1)                        {printf("%d ",num1);                        count++;                        }                  num1++;                  }while(num1*b)        printf("First number must beless than second number-reenter ");    }while(*a>*b); } int perfect(int a) {int i,sum=1; for(i=2;i
