To print the string pattern using c

Question:

To print the string pattern using a given odd length word which should be printed from the middle of the word.

Logic:

• Get the input string from the user.
• Find the middle position of the string.
• Prints the second half of the string.
• And then prints the first half by including the second half.

Algorithm:

1. Calculate the length of the input string.
2. And find the middle position of the string.
3. Then print the spaces according to the length.
4. Print the second half of the string orderly.
5. Then print the first half by including the second half that gives the pattern like structure.

Program:

#include<stdio.h>
void main()
{
    char a[20];
    int i,j,n,c;
    clrscr();
    printf("enter the string:");
    gets(a);
    n=strlen(a);//stores the length of string
    c=n/2;//finds middle index of the string
    for(i=0;i<n;i++)
    {
	for(j=n-1;j>i;j--)//prints the spaces
	{
	   printf("  ");
        }
	for(j=c;j<=c+i&&j<n;j++)//prints the right half of the string
	{
	   printf("%c",a[j]);
	}
	if(i>c)//checks whether it prints all the right half elements
	{
           for(j=0;j<i-c;j++)//prints the left half of the string
	   {
	       printf("%c",a[j]);
	   }
        }
	printf("\n");
    }
    getch();
}
