I am not getting the desired output for my C program can anyone please have a look on the code and help me to rectify the error ?
Desired output and actual output of my code is:
My Code is:
#include <stdio.h>
#include <conio.h>
void main()
{
int i,j,k;
int blank=0;
int lines = 6;
char symbol='A';
int temp ;
int diff[7]= {0,1,3,5,7,9,11};
k=0;
for(i=lines;i>=0;i--)
{
printf("\n");
symbol = 'A';
for(j=i;j>=0;j--)
printf("%c ",symbol++);
blank = diff[k++];
for(j=0;j<blank;j++)
printf(" ");
symbol = 'F' - (blank/2);
if (blank== 0)
temp = i-1;
else
temp = i;
for(j=0;j<=temp;j++)
printf("%c ",symbol--);
}
getch();
}

Answer 1

Your have written the code in a right way. You have to change the line
for(j=0;j<blank;j++)
printf(" ");
to
for(j=0;j<blank;j++)
printf(" "); // increase one more space
And also try to avoid using void main().Here is your edited code;
#include <math.h>
#include <stdio.h>
int main()
{
int i,j,k;
int blank=0;
int lines = 6;
char symbol='A';
int temp ;
int diff[7]= {0,1,3,5,7,9,11};
k=0;
for(i=lines;i>=0;i--)
{
printf("\n");
symbol = 'A';
for(j=i;j>=0;j--)
printf("%c ",symbol++);
blank = diff[k++];
for(j=0;j<blank;j++)
printf(" ");
symbol = 'F' - (blank/2);
if (blank== 0)
temp = i-1;
else
temp = i;
for(j=0;j<=temp;j++)
printf("%c ",symbol--);
}
return 0;
}
And do not forgot to include headers.

Answer 2

The problem is here
for(j=0;j<blank;j++)
printf(" ");
^
A
You are printing only a single space it should be two.So that one space corresponds to the alphabet and another to the actual space
printf(" ");
^^
A(space)

Answer 3

Firstly, you're printing the wrong number of blanks. And the number you need can be worked out with a small piece of arithmetic.
Secondly, you don't need that messy calculation to work out the first symbol to print out after the blanks because you've already worked it out.

Answer 4

You need to use more blank spaces
Use 0, 2, 6... so on

Answer 5

Your "diff" array is too small. You're accounting for the missing characters on the left side of the pattern, but not on the right side. Try making the first three elements {0, 2, 6...} and see if that works, and then work on extrapolating the correct pattern from there
