To print the lowercase alphabets from ‘a’ to ‘z’,

  • We will declare a variable for loop counter (alphabet) and initialize it by 'a' (lowercase ‘a’).
  • We will check the condition whether loop counter is less than or equal to 'z', if condition is true numbers will be printed.
  • If condition is false – loop will be terminated.

Program to print all lowercase alphabets from ‘a’ to ‘z’ using while loop in C



#include <stdio.h>

int main()
{
	//loop counter or a variable that
	//will store initial alphabet,
	//from where we will print the alphabets
	char alphabet;
	//assigning 'a' as initial alphabet
	alphabet='a';

	//print statement
	printf("Lowercase alphabets:\n");

	//loop statement, that will check the condition
	//and print the alphabets from 'a' to 'z'
	while(alphabet<='z')
	{
		//printing the alphabets
		printf("%c ",alphabet);
		//increasing the value by 1
		alphabet++;
	}

	return 0;
}

Output

Lowercase alphabets:
a b c d e f g h i j k l m n o p q r s t u v w x y z
