Question

a. Ask the user for the input of a letter (char type). Write a function that takes a char as the argument (parameter) and returns the ASCII value of that char back to the caller. Call the function using the char variable and taking input from the user (no validation required). Display the value in ASCII.

b. Write a program that takes a char as the argument (parameter) and uses a loop to interrogate the char, calling a function that is looking for characters with the ASCII code of 97 through 122. Create a loop that goes for 10 times. Display any characters that are not in that range and include a small message.

c. write a program that takes a char as the argument (parameter) and checks to see if it (the char) is a punctuation mark. From within the function display “the character was (was not) a punctuation mark!”.

/*Please answer a,b and c. C++ please. Thank you so much*/

Answer 1

#include<iostream>
using namespace std;
//a
int getAscii(char c)
{
   return (int)c;
}
//b
//function that checks whether the given char is in range 97 to 122
//and display message if not in the range
void check(char c)
{
   if(97<=c && c<=122)
   cout<<"Yes "<<c<<" in range 97 to 122\n";
   else
   cout<<"No "<<c<<" is not in range 97 to 122\n";
}
//c
//method to check entered char is a punctuation mark
void check_punct()
{
       char c;
       char p[] ={'.','?','!',',',';',':','-','{','}','[',']','(',')','\'','\"'};
   cout<<"Enter a char:";
   cin>>c;
   for(int i=0;i<15;i++)
   if(c==p[i])
   {
       cout<<"yes "<<c<<" is punctuation mark\n";return;
   }
   cout<<"no "<<c<<" is not a punctuation mark\n";
}
int main()
{
   //a
   char c;
   cout<<"Enter a char:";
   cin>>c;
   //calling method to find ascii value
   cout<<"Ascii value of "<<c<<" is "<<getAscii(c)<<endl;
  
   //b
   int i=0;
   while(i<10)
   {cout<<"Enter a char:";
   cin>>c;
   check(c);
      
       i++;  
   }
  
   //c
   check_punct();
   return 0;
}

output:

Enter a char:c
Ascii value of c is 99
Enter a char:a
Yes a in range 97 to 122
Enter a char:b
Yes b in range 97 to 122
Enter a char:c
Yes c in range 97 to 122
Enter a char:d
Yes d in range 97 to 122
Enter a char:A
No A is not in range 97 to 122
Enter a char:e
Yes e in range 97 to 122
Enter a char:Q
No Q is not in range 97 to 122
Enter a char:$
No $ is not in range 97 to 122
Enter a char:@
No @ is not in range 97 to 122
Enter a char:1
No 1 is not in range 97 to 122
Enter a char:2
no 2 is not a punctuation mark
