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.

using the Range feature starts at @6:31

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 ).

1st of all thank u so much for explaining everything so slowly & clearly
as u ve asked for the simple program:
#include <stdio.h>
#include <stdlib.h>

int main()
{
char c= 'a';
switch(c){
case 'a' ... 'z':
printf("%c is lower case", c);
break;

case 'A' ... 'Z':
printf("%c is Upper case", c);
break;
default:
printf("default");
}
return 0;
}
changing the char value to M will execute 2nd case

THANK YOU SO MUCH SIR THIS HELPED A LOT I WAS STUCK IN A CODE THAT NEEDED RANGE USING SWITCH STATEMENTS

[mohammedkhalid]

Code is as follow:


#include<stdio.h>
#include<conio.h>
int main(){
char x;
printf("pleaes enter the charcter.\n");
scanf("%c", &x);

switch(x){

case 'A' ... 'Z':
printf("the latter is upper case.\n");
break;

case 'a' ... 'z':
printf("the latter is lower case.\n");
break;

default:
printf("please, enter the correct charcter.\n");
}



getch();
return 0;
}

In second case statement we can specify case 'a' ... 'z' :
print("%c between and z\n");
By modifying char value we get either one of the case

sir you ar doing great.i have watched all your videos of c tutorial till now.Thank you sir

[RajMadhok]

Great job sir! U are a very hardworking person . Keep it up

[mayankyadav]

Thank you sir I have learned lots of concept from your video in simple way :) and still learning. I didn't know about range in switch case. Thanks

[Hideto_]

#include <stdio.h>
int main()
{ char ch;
scanf("%c", &ch);
switch(ch)
{ case 'a' ... 'z':
printf("%c is lowercase");
break;
case 'A' ... 'Z':
printf("%c is uppercase");
break;
default:
printf("match not found");

}


return 0;
}

ohh my god wow what a solution hats off

[enesyuce]

thank you very much. I will use this in my arduino project

[danjediaelcaranay]

Hello, how about if the value for range is negative?

[rishirajagarwal]

Sir when running on codeblocks it is compiling well but when I am running it it says do you want to build and if I say yes then it shows 2 errors saying multiple definition of main

[godslove]

Pease can someone help? I am trying it in java with Eclipse Compiler, but it is not working. Can any one tell me how to compute switch stat in eclipse with range value please.

[jerahmaypasion]

Sir. In switch use in calculator..
I want to continue the program with out using getch or do and while. Only
If and else . Can you help me..

[alisyed]

You should do a playlist for data structures

[simbol]

Thanks alot.
This is what I think it's looks like please help me correct it if there is any mistake but the program ran on my system.

#include<stdio.h>
#include<stdlib.h>
#include<conio.h>

int main()
{
char c;
scanf(" %c", &c);

switch (c) {
case 'A' ... 'Z':
{
printf("\n %s is a capital letter", &c);
break;
}
case 'a' ... 'z':
{
printf("\n %s is a small letter", &c);
break;
}
}
getch();
return 0;
}

[vivekdsouzaa]

Sir, In the following program, it is not executed after the scanf portion i.e enter the no., After entering the no., BLANK ... PLZ help me out of this... I am a beginner...
#include<stdio.h>
#include<conio.h>
int main()
{
int x;
printf("Enter the number\n");
scanf("%d\n", &x);
switch( x ){
case 0 ... 12:
printf("YOU ARE A CHILD\n");
break;
case 13 ... 19:
printf("YOU ARE A TEENAGER\n");
break;
case 20 ... 40:
printf("YOU ARE AN ADULT\n");
break;
case 41 ... 100:
printf("YOU ARE A VETERAN");
break;
default:
printf("YOU ARE AN ALIEN");
}

getch();
return 0;

}
