To remove characters in string without including alphabets

Question:

Write a program to remove characters in the string without including alphabets.

Logic:

• Get the input string from the user by including symbols.
• Checks for non-alphabets in the string and removes it.
• Then prints the remaining characters.

Algorithm:

1. Get the input string from the user.
2. Then check the individual characters in the string for non-alphabets.
3. And removes the character in the string using swapping.
4. Then print the remaining characters in the string.

Program:

#include<stdio.h>
void main()
{
	char a[100];
	int i,j,n;
	clrscr();
	printf("enter the string:");
	gets(a);
	n=strlen(a);
	for(i=0;i<n;i++)
	{
		if((a[i]>65&&a[i]<91)||(a[i]>96&&a[i]<123))//checks for the alphabet
		{
			continue;
		}
		else
		{
			for(j=i;j<n;j++)//removes the character other than alphabet
			{
				a[j]=a[j+1];
			}n--;//after removing decrementing the length
		}
	}
	printf("string after removing characters:");
	puts(a);//prints the string
	getch();
}
