In this article, we will discuss the concept of C Program for Display Alphabets using ASCII value
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 using ASCII in C programming language
The program displays all the upper case and lower case alphabet letters between a to z using for loop in C language
Program 1
#include <stdio.h> #include <stdlib.h> int main() { char ch;//char variable declaration //Printing upper case Alphabets printf("Uppercase Alphabets are: \n"); for(ch=65; ch<=90; ch++){ printf("%c",ch); printf(" "); //display uppercase Alphabets with space } printf("\n");//move to next line //Printing lower case Alphabets printf("\nLowercase Alphabets are: \n"); for(ch=97; ch<=122; ch++){ printf("%c",ch); printf(" "); //display lowercase Alphabets with space } //printf("Hello world!\n"); getch(); return 0; }
When the above code is executed, it produces the following result
In the above program, we are using two for loops, one is used to print upper case letters and another to print lower case letters
Approach
The program displays all the upper case and lower case alphabet letters between a to z using while loop in C language
Program 2
#include <stdio.h> #include <stdlib.h> int main() { char ch;//char variable declaration //Printing upper case Alphabets printf("Uppercase Alphabets are: \n"); ch=65; while(ch<=90){ printf("%c",ch); printf(" "); //display uppercase Alphabets with space ch++; } printf("\n");//move to next line //Printing lower case Alphabets printf("\nLowercase Alphabets are: \n"); ch=97; while(ch<=122){ printf("%c",ch); printf(" "); //display lowercase Alphabets with space ch++; } //printf("Hello world!\n"); getch(); return 0; }
When the above code is executed, it produces the following result
In the above program, we are using two while loops, one is used to print upper case letters and another to print lower case letters
Approach
The program displays all the upper case and lower case alphabet letters between a to z using the do-while loop in C language
Program 3
#include <stdio.h> #include <stdlib.h> int main() { char ch;//char variable declaration //Printing upper case Alphabets printf("Uppercase Alphabets are: \n"); ch=65; do{ printf("%c",ch); printf(" "); //display uppercase Alphabets with space ch++; }while(ch<=90); printf("\n");//move to next line //Printing lower case Alphabets printf("\nLowercase Alphabets are: \n"); ch=97; do{ printf("%c",ch); printf(" "); //display lowercase Alphabets with space ch++; }while(ch<=122); //printf("Hello world!\n"); getch(); return 0; }
When the above code is executed, it produces the following result
In the above program, we are using two do-while loops, one is used to print upper case letters and another to print lower case letters
