Code to print alphabet A pattern in C language

Hello there!

   Welcome to our blog in this tutorial we will see how to write code to print alphabet A pattern in C language using only two loops in a simple way.

before that once we will see the algorithm of the program. Repeat an algorithm is nothing but steps involved in the process of development of the program, in this program, there are 11 steps involved

                               

                                                     Algorithm of A pattern program

Let's see the steps 

step 1: start

step 2: initialize variables p,q,a,b,c,d.

step 3: read a from user.

step 4: b=a.

step 5 : c=a.

step 6: d=(a\2)+1.

step 7:repaet the step untill p=a.

  step 7.1:Repeat the step until q=c.

  step 7.2: if q=b or q=b.

                    print *.

                 Else if p=d and q>b.

                      print *.

                 Else print one space.

step 8:b=b-1.

step 9: c=c+1.

step 10: print new line

step 11: stop.

  

By observing this algorithm we get awareness about the program how it will work step by step. for a better understanding of the program, let's see the flow chart of the program. i hope that will give more knowledge about the program.

flow chart of A pattern program

finally its program time lets take a look

program

#include
#include
int main()
{
int p,q,a,b,c,d;
printf("enter  a number :");
scanf("%d",&a);
b=a;
c=a;
d=(a/2)+1;
for(p=1;p<=a;p++)
{
for(q=1;q<=c;q++)
{
   if(q==b||q==c)
   {printf("*");}
   else if(p==d&&q>b)
   {printf("*");}
   else{printf(" ");}
}

b--;c++;
printf("\n");
}
getch();
return 0;
}

Output :
