Question

C++ PLEASE

Write a program to prompt the user to display the following menu:

Guess-Number                        Concat-names             Quit

• If the user selects Guess-number, your program needs to call a user-defined function called int guess-number ( ). Use random number generator to generate a number between 1 – 100. Prompt the user to guess the generated number and print the following messages. Print the guessed number in main ():

Guess a number: 76

96:

Too large

10

Too small

70

Close

Do you want to quit? Q

• If the user selects Concat-name, prompt the user how many names to concatenate and then enter all the first and las names and store then into a two one-dimensional array. Your program needs to call a user-defined function called void sort-name ( char [] , char[]) to concatenate the first name and the last name and print the names in this function.

How many names: 3

First name                   last name                                Combined

Sue                              Smith                                       Sue Smith

Alan                             Davidson                                 Alan Davidson

David                           Lee                                          David Lee

Do you want to quit? Q

C++ please

Answer 1

Please find the program below.

#include <iostream>
#include <stdlib.h> /* srand, rand */
#include <time.h>

using namespace std;
void sort_name ( string firstname[] , string lastname[],int count){
cout<<"First name"<<"\t\t"<<"Last name"<<"\t\t"<<"Combined name"<<endl;
cout<<"------------------------------------------------------------"<<endl;
for (int i=0;i<count;i++){
cout<<firstname[i]<<"\t\t\t"<<lastname[i]<<"\t\t\t"<<firstname[i]<<" "<<lastname[i]<<endl;
}
}

int main()
{   
int number=0;
cout<<"1. Guess-Number"<<endl ;
cout<<"2. Concat-names"<<endl;
cout<<"3. Quit"<<endl;
cin>>number;
switch (number)
{
case 1:
{
int random_number=0,guess_number;
char ans;
/* initialize random seed: */
srand (time(NULL));

/* generate secret number between 1 and 10: */
random_number = rand() % 100 + 1;
while(1){
cout<<"Guess the number "<<endl;
cin>>guess_number;
if(guess_number<random_number){
cout<<"Too small"<<endl;
}
else if (guess_number>random_number){
cout<<"Too large"<<endl;
}
else{
cout<<"Close"<<endl;
break;
}
}
cout<<"Do you want to quit? Press Q to quit ..."<<endl;
cin>>ans;
if(ans=='Q'){
exit(0);
break;}
}
case 2:{
while(1){
int name;
char ans;
cout<<"How many names ?" <<endl;
cin>>name;
string firstname[name];
string lastname[name];
for (int i=0;i<name;i++){
cin>>firstname[i];
cin>>lastname[i];
}
sort_name (firstname,lastname,name);
cout<<"Do you want to quit? Press Q to quit ..."<<endl;
cin>>ans;
if(ans=='Q'){
exit(0);
break;
}
}
}
case 3:{ exit(0); }
}
return 0;
}
