Problem statement:-   Program to print the Solid Diamond Alphabet Pattern.

 Data requirement:-

   Input Data:- row_size

  Output Data:- x

  Additional Data:-in or inn(for python), out, p

Program in C

Here is the source code of the C  Program to print the Solid Diamond Alphabet Pattern.

Code:

#include<stdio.h>

#include<math.h>

int main()

{

    int out,in,p,x=0;

    printf("Enter the row size:");

    int row_size;

    scanf("%d",&row_size);

    for(out=row_size;out>=-row_size;out--)

    {

     for(in=1;in<=abs(out);in++)

     {

    printf(" ");

     }

    for(p=row_size;p>=abs(out);p--)

    {

    printf("%c ",x+65);

    }

      if(out>0)

    x++;

    else

    x--;

    printf("\n");

}}
