[/FONT] Question No. 1 Marks [10]


This is a sample code for guessing your personality using if-else statement.

Code:

char ch; cout<<”Type a character in small letter [a-z] :”; cin>>ch; If (ch= =’l’) cout<<”You are a Lucky person”; else If (ch= =’a’ || ch==’z’) cout<<”You are an extremist (sorry to say)”; else If (ch= =’u’) cout<<”You are Unlucky, wish you good luck.”; else cout<<”You are Unpredictable person”;

Your have to write a program that performs EXACTLY the same task using switch-statement.

Note: The code must be non-cryptic and easy to read.

Question No. 2 Marks [10]

Following code generates Fibonacci series for given limit number.

Code:

void main() { unsigned int i=0,j=0,sum=1,num; cout<<”Enter the limit for the series "; cin>>num; while(sum<num) { cout<<sum<<”\n”; i=j; j=sum; sum=i+j; } getch(); }

Modify the code such that the same objective is achieved by using Modular approach.

Hint: Define a function Fibonacci that takes series limit as input and prints the results.

Final solution of this assignment please find in the code
Solution 1

Code:

#include <iostream> using namespace std; main() { char ch; cout << "Type a character in small letter [a-z] :"; cin >> ch; switch(ch) { case 'l': { cout<<"You are a Lucky person"; break; } case 'a': case 'z': { cout<< "You are an extremist (sorry to say)"; break; } case 'u': { cout<<"You are Unlucky, wish you good luck."; break; } default: { cout<<"You are Unpredictable person"; break; } } system("pause"); }

Solution 2

Code:

#include <iostream> using namespace std; void Fibonacci(int,int,int,int); main() { unsigned int i=0,j=0,sum=1,num; cout << "Enter the limit for the series "; cin >> num; Fibonacci(num,i,j,sum); system("pause"); } void Fibonacci(int num,int i,int j,int sum) { cout << sum << endl; i = j; j = sum; sum = i + j; if (sum < num) Fibonacci(num,i,j,sum); }
