Dear Shamnar,

Here is your solution for string problem. I have solved it using Turbo 3.0. Pls. feel free if you need. Just copy the program using notepad using .txt extension and open it in Turbo IDE. Save the Program in Turbo IDE using .C extension. just press CTRL+F9. Input two strings and see the output. str1 is your answer.

ANSWER:

void main()
{
        char str1[25];
	char str2[25];
	int flag=1;
	char *ptr1, *ptr2, *temp;
	clrscr();
 
	printf("Enter two string");
	gets(str1);
	gets(str2);
 
	ptr1=str1;
	ptr2=str2;
 
	while(*ptr1 != '\0')
	{
		while(*ptr2 != '\0')
		{
			if(*ptr1 != *ptr2)
				ptr2++;
			else
			{
				temp=ptr1;
				while(*ptr1 != '\0')
				{
					if(*ptr1 != *ptr2)
					{
						flag=0;
						break;
					}
					ptr1++;
					ptr2++;
				}
				if(flag==1)
					*temp='\0';
			}
		}
		ptr1++;
		ptr2=str2;
	}
                printf("\nThe output is\t");
	puts(str1);      // In str1 the repeated string has been removed.
 
	getch();
}
