Question

Write a program in C++ that prompts the user to input an integer between 0 and 35. The prompt should say Enter an integer between 0 and 35:.

If the number is less than or equal to 9, the program should output the number; otherwise, it should output:

A for 10
B for 11
C for 12
. . .
and Z for 35.

(Hint: For numbers >= 10, calculate the ACSII value for the corresponding letter and convert it to a char using the cast operator, static_cast<char>().)

Expert Solution

Step 1

C++ code for above :

#include<iostream>

using namespace std;

int main(){

//prompt to enter number

cout<<"Enter an integer between 0 and 35: ";

//get number

int num; cin>>num;

//check if number is valid

if( num >=0 && num <= 35 ){

//if number is less than equal to 9

if( num <=9 ){

cout<<num;

}

//otherwise

else{

//cast the integer into required character

char c = static_cast<char> ( num - 10 + 'A' );

cout<<c;

}

else{

cout<<"NOT VALID INPUT!!";

}

return 0;

}
