C Program for print all Alphabet between given range using loops

In this article, we will discuss the concept of C Program for print all Alphabet between given range using loops

In this post, we are going to learn how to display all the upper case(A to Z) and lower case (a to z) Alphabets between given range using loops on C programming language

C program to print all Alphabet between the given range

Code to print all Alphabet between given range using for loop

The program displays all the upper case and lower case alphabet letters between given range using for loop in C language

Program 1

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

int main()
{
    char i,ch1,ch2;
    printf("Enter two Alphabet of the range: ");
    scanf("%c %c",&ch1,&ch2);
//store the entered alphabets in variables ch1,ch2

    for(i=ch1; i<=ch2; i++){
     printf("%c ",i);

//display uppercase or lower case Alphabets with space
}
getch();
    return 0;
}

When the above program is executed, it produces the following result

Case 1

Enter two Alphabet of the range: i
n
i j k l m n

Case 2

Enter two Alphabet of the range: A
H
A B C D E F G H

In the above program, we are using a for loop, this is used to print upper case Alphabet letters or lower case Alphabet letters

Approach

In the above program, the user is asked to enter two Alphabet and entered Alphabet is stored in character variable ch1,ch2;
In this for loop, it is initialized by i=ch1 and checks the condition of (i<=ch2);
If the test expression is true, the program is printed the Alphabets letters between given Alphabets
If the test expression is false, the loop is terminated

Code to print all Alphabet between given range using while loop

The program displays all the upper case and lower case alphabet letters between given range using while loop in C language

Program 2

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

int main()
{
    char i,ch1,ch2;
    printf("Enter the two Alphabet of the range: ");
    scanf("%c %c",&ch1,&ch2);
//store the entered alphabets in variables ch1,ch2
    i=ch1;
    while( i<=ch2){
     printf("%c ",i);

//display uppercase or lowercase Alphabets with space
 i++;
}
getch();
    return 0;
}

When the above program is executed, it produces the following result

Case 1

Enter two Alphabet of the range: m
z
m n o p q r s t u v w x y z

Case 2

Enter two Alphabet of the range:G
T
G H I J K L M N O P Q R S T

In the above program, we are using a while loop, this is used to print upper case Alphabet letters or lower case Alphabet letters

Approach

In the above program, the user is asked to enter two Alphabet and entered Alphabet is stored in character variable ch1,ch2;
In this while loop, it is initialized by i=ch1 and checks the condition of (i<=ch2);
If the test expression is true, the program is printed the Alphabets letters between given Alphabets
If the test expression is false, the loop is terminated.

Code to print all Alphabet between given range using do-while loop

The program displays all the upper case and lower case alphabet letters between the given range using do-while loop in C language

Program 3

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

int main()
{
    char i,ch1,ch2;
    printf("Enter the two Alphabet of the range: ");
    scanf("%c %c",&ch1,&ch2);
//store the entered alphabets in variables ch1,ch2
    i=ch1;
   do{
     printf("%c ",i);

//display uppercase or lowercase Alphabets with space
 i++;
} while( i<=ch2);
getch();
    return 0;
}

When the above program is executed, it produces the following result

Case 1

Enter two Alphabet of the range: o
y
o p q r s t u v w x y

Case 2

Enter two Alphabet of the range: K
S
K L M N O P Q R S

In the above program, we are using a do-while loop, this is used to print upper case Alphabet letters or lower case Alphabet letters

Approach

In the above program, the user is asked to enter two Alphabet and entered Alphabet is stored in character variable ch1,ch2;
In this do-while loop, it is initialized by i=ch1 and checks the condition of (i<=ch2);
If the test expression is true, the program is printed the Alphabets letters between given Alphabets
If the test expression is false, the loop is terminated
