Welcome viewers to
another new ‘C’ structure or pattern ........
In this blog, we will print a "
Pine tree" with the help of ‘for
loop’,’ while loop and some ‘if-else’ function. So, let's start...First, let's look at the pattern of the tree.
 |
| TREE STRUCTURE IN 'C' PROGRAMMING |
We can see the tree has three same types of ‘Head part’ i.e
upper part. And then followed by the five stared ‘Stock part’ and at the base
of it, there is also five “=” character.
So, we need to first with the ‘head part’. As this part
continues for three times, so we can make a ‘while loop’ with a condition of looping three times and printing the same pattern.
For ‘Stock part’ we need to use a simple ‘for
loop’ that will print a ‘*’ with newline character at the time of each
star printing.
For ‘Base’ there is also a simple ‘for loop’ that will
iterate 5 times to print the “=” characters.
Now, let's see how the program is going on :
 |
| PROGRAMMING CODE IN 'C' |
(i)”HEAD PART” or “UPPER PART”:-
Here, we have first set a while loop that will iterate 3 times as stated
earlier. Then we have made a for loop whose value will start from 1 and it will
check the condition i<=n(here,n=3) which means the loop will iterate until the
loop is executed 3 times. Then an inner is set with a condition j<=n-i(for
first iteration n=3 and i=1, for second i=2, third i=3 and so on) for printing
the spaces before printing the stars to give the proper shape of a tree. Here,
the loop will print spaces until j<=n-i (for the first case it prints 2 spaces
as j=3-1=2; for the second case it prints 1 space as j=3-2=1; for third, it will
print any space as j=3-3=0).
Then the next ‘for loop’ comes for the printing of stars according
to the pattern. Here the condition will be different i.e. k<=(2*i-1) as we
need to print stars in ‘odd order’. For first case i=1;k=1; it prints only one
star (it should be noted, the spaces are printing at their respective positions
before printing stars as per previous ‘for loop’), for second case i=2;k=3,
prints 3 stars and for third case i=3;k=5 prints 5 stars.
Now, as the while loop is given so the same will iterate or
execute 3 times and thus printing the “head part” of the ‘TREE’.
while(x<=3)
{
for(i=1;i<=n;i++)
{
for(j=1;j<=n-i;j++)
{
printf(" ");
}
for(k=1;k<=2*i-1;k++)
{
printf("*");
}
printf("\n");
}
x++;
}
(ii)”STOCK PART”:-
It is a
simple part. Here we have for loop with a ‘if-else’ function. The loop is
executed a total of 10 times(5 times for the stock part and the rest for the base part).
"If statement" is given to check the condition that the loop
is iterated less than 6 times for ‘stock printing’ and inside if statement
there is another for loop that will print spaces and then stars with a new line the character at the time of each iteration.
Thus, the ‘stock part’ is printed.
for(i=1;i<=10;i++)
{
if(i<6)
{
for(j=1;j<=2;j++)
{
printf(" ");
}
printf("*\n");
(iii)”BASE PART”:-
In the previous
‘if statement’ we get the ‘else part’ also, so it is basically for base part
printing(“=”). The for loop will execute another 5 times thus completing its
total 10 iterations (5 in ‘if’+5 in ‘else’) and printing the’=’ characters . Thus
printing the base part.
for(i=1;i<=10;i++)
{
if(i<6)
{
for(j=1;j<=2;j++)
{
printf(" ");
}
printf("*\n");
}
else
printf("=");
}
}
This is all about printing a “TREE” using ‘C’ Programming.
It can also be done in another way (stay tuned). Thank you..............
