Question

In C programming language have a program request the user to enter an uppercase letter. Use nested loops to produce a pyramid pattern like this:

The pattern should extend to the character entered. For example, the preceding pattern would result from an input value of E. Hint: Use an outer loop to handle the rows. Use three inner loops in a row, one to handle the spaces, one for printing letters in ascending order, and one for printing letters in descending order.

#include<stdio.h>
#include<conio.h>
int main()
{
char input_character,read,c;
int sp;
printf("Enter an alphabet : ");
scanf("%c",&input_character);
if(input_character>='a' && input_character<='z')
input_character=input_character-32;
for(read='A'; input_character>=read; read++)
{
for(sp=input_character-read; sp>=1; sp--)
printf(" ");
for(c='A'; read>=c; c++)
printf("%c",c);
for(c=read-1; c>='A'; c--)
printf("%c",c);
printf("\n");
}
getch();
return 0;
