Twitter is a popular social media. It allows its users to exchange tweets (short messages of a
maximum of 140 Characters). Write a program that prompts the user for a tweet and then flips
the letter-case of each letter in the tweet. Apply the flipping code again to get the original
message If the user enters an empty tweet then the program shall show the message \"Empty
tweet !\". Refer to the sample input/output given below. Your program should have one c-string
(call it twt []).
Solution
#include
#include
#include
using namespace std;
void flipCase( char* s )
{
for(int i=0;s[i];i++)
if (islower(s[i])) s[i] = toupper(s[i]); //if letter is in uppercase convert to lowercase . If letter
is lowercase convert to upper case
else s[i] = tolower(s[i]);
}
int main()
{
char twt[ 100 ];
cout << \"Enter your tweet: \";
cin.getline(twt,141);
flipCase(twt);
cout<<\"\ Tweet after flipping letter-case is: \";
cout << twt << endl;
cout<<\"\ Tweet after flipping letter-case again is: \";
flipCase(twt);
cout << twt << endl;
return 0;
}
output:.
