Using Range in the Case Values of Switch Statement | C++ Programming Video Tutorial

In this c++ programming video tutorial you will learn to use Range in the switch statement case values with example.

GCC Compiler allows you to use this feature. usage of the range in the case values of the switch statement allows the programmer to execute a set of statements for a range of values.

Syntax for using the Range in switch case values
case LowerLimit ... upperlimit:

while using this feature you have to follow 2 rules.
LowerLimit can not be greater than the upperlimit.
none of the cases should contain overlapping values ( one value should not have matches in 2 or more cases ).

Thanks for your tutorials.

#include <iostream>
using namespace std;
int main()
{
char input ;
cout<<"Enter the alphabet:";
cin>> input;
switch(input){
case 'A' ... 'Z' :cout<<"You Entered upper case";
break;
case 'a' ... 'z':cout<<"You Entered lower case";
break;
}
return 0;
}

WOW! i almost learned C++ program thank you i watched all your series

#include <iostream>
using namespace std;
int main(){
char result = 'G';
int ascii = int(result);
switch(result){
case 97 ... 122:{
cout <<result <<" is lowercase.";
break;
}
case 65 ... 90:{
cout <<result << " is uppercase.";
break;
default:{
cout << "you have no matching character";
}
}
}
return 0;
}

#include <iostream>

using namespace std;

int main()
{char x;
cout << "Please insert a char" << endl;
cin >> x;

switch(x){

case 'A' ... 'Z':
cout << "alphabet is in higher case";
break;
case 'a' ... 'z':
cout << "alphabet is in lower case";
break;
default:
cout << "no alphabet found";
}


return 0;

#include<iostream>

using namespace std;



int main(){
char x;
cin >> x;

switch(x){
case 'a' ... 'z':

cout << " is a lowercase letter ";

break;

case 'A' ... 'Z':
cout << "is a uppercase letter";
break;

default:
cout << "default statements";
break;

}
return 0;
}

Identifing uppercase and lowercase:
#include <iostream>
using namespace std;
int main(){
char letra;
cout<<"Ingrese La Letra A Identificar :"<<endl;
cin>>letra;
switch (letra){
case 65 ... 90:
cout<<"Es Mayuscaula"<<endl;
break;
case 97 ... 122:
cout<<"Es Minuscula"<<endl;
break;
default:
cout<<"NO ES UNA LETRA"<<endl;
}
}

made the user enter some value:src code is here:

#include <iostream>

using namespace std;

int main()
{
int x ;
cout<<"enter some value"<<endl;
cin>>x;

switch(x)
{
case 1 ...10:
cout<<"this is range 1:"<<endl;
break;
case 11 ... 20:
cout<<"this is range 2:";
break;
case 21 ... 30:
cout<<"this is range 3:";
break;
default:
cout<<"enter some values";



}
}

Hello I am wondering if there is a way to use range but exclusive (not including the start and end numbers). Thank you your videos are awesome keep it up

[Finalleigh]

#include <iostream>
using namespace std;
int main()
{char input;
cout<<"Enter a letter"<<endl;
cin>>input;
switch (input)
{case 'A' ... 'Z' :
 cout<<"You have entered an uppercase letter";
 break;
 case 'ba' ... 'z':
  cout<<"You have entered a lowercase letter";
  break;
  default :
   cout<<"You have not entered a letter";
}
}

Here's my way of doing your challenge program.

#include <iostream>

int main()
{
char ch{};
std::cin >> ch;

switch ((int)ch)
{
case 65 ... 90:
std::cout << "Entered character is in UPPERCASE.\n";
break;
case 97 ... 122:
std::cout << "Entered character is in lowercase.\n";
break;
default:
std::cout << "Please enter from a-z (lowercase) or A-Z (uppercase)\n";
}

return 0;
}
