Cross pattern program in C

Question:

Cross pattern program in C. Write a program to print the x-cross pattern for odd length. Must write this pattern program in C.

Pattern program logic:

• Get the odd length input from the user.
• Then insert the characters from top to bottom diagonally.
• And insert the characters from bottom to top also in a diagonal position.
• Then print the pattern.

Algorithm:

1. Get the input string from the user.
2. Then checks the diagonal position of the array and insert into it from top to bottom.
3. And then checks the diagonal position from bottom to top to insert the string.
4. At last, prints the array to display pattern.

Program:

include<stdio.h>
void main()
{
    int i,j,n,x,y,m=0;
    char a[20],c[10][10];
    clrscr();
    printf("enter the word with lenth odd:");
    gets(a);
    n=strlen(a);
    for(i=0;i<n;i++) \\insert into array from top to bottom
    {
       for(j=0;j<n;j++)
       {
	  if(i==j)\\ assign values to array only when i&j are equal otherwise prints null
	  {
	      c[i][j]=a[m];
	      m++;
	  }
	  else
	  {
	      c[i][j]='\0';
	  }
       }
    }
    i=n-1;
    m=0;
    for(j=0;j<n;j++)\\insert into array from bottom to top
    {
	c[i][j]=a[m];
	i--;
	m++;
    }
    for(i=0;i<n;i++)\\prints the cross word
    {
	for(j=0;j<n;j++)
	{
	    printf("%c",c[i][j]);
	}
	printf("\n");
    }
    getch();
}
