Writing Letter V with c language

HOw to c /* A complete program on how to write Letter V with C Language */

/* If you don't understand below program send mail to vas.shrinivas002@gmail.com */

#include<stdio.h>
#include <conio.h>

int main(void)
{
clrscr();

void call();
void useme();
call();
useme();
}

void call()
{
int k,l;
for(k=1;k<=3;k++)
{
for(l=1;l<=k;l++)
{
if(l==k) {
gotoxy(k,l);
printf("*"); }
}
}//for
}
void useme()
{

int i,j,c;

for (i=1;i<=3;i++)
{

c=0;

for(j=6;j>=i;j--)
{
c=c+1;
}

gotoxy(c,i);
printf("*");
}

getchar();

How to Write Letter B with c

/*prog for Letter B */
main()
{
int i=1;

for(i=1;i<=6;i++)

{

if(i==1 || i==4 || i==6)
{
printf("********");
printf("\n");
}

if(i!=1 && i<=5)

{
printf("* *");
printf("\n");
}

}
}

Sorting Technique

First understand this:

Let us assume we taken below array

var a=["9","8","3","2","8","11","7"]

First understand this:

step1:-->if (r[i]<=r[j])

t=t+1;

Above array 11 is biggest number,Based on above condition t will return
zenrate:t=1 for Highest no 11
t=2 for second biggest no 9
t=3 for third biggest no 8
t=4 for fourth biggest no 7
t=5 for fifth biggest no 3
t=6 for least no---------2

Now i am inserting highest number in last of array index that b[5]=r[i]

not understand see this b[5]=11,b[4]=9,b[3]=8,b[2]=7,b[1]=3,b[0]=2

Don't forget this is the key for writing sorting order

Order in this way:

Display in Ascending Order:a=["9","8","3","2","8","11","7"]

for(i=0;i<=4;i++)
{

document.write(b[i]);--->out put in this order 2,3,7,8,9,11
}

Also,If u want display in Descending Order this code will help you how

for(i=4;i>=0;i--)
{
document.write(b[i]);--->Out put is 11,9,8,7,3,2
}
----------------------------------------------------------------------------------
Next you can change below code in your environment(c,c++,c#,java)

<html>

<script type="text/javascript">

var r=new Array();

r[0]=1;
r[1]=237654;
r[2]=99999;
r[3]=99;
r[4]=10000;

var b=new Array();

var t=0;

document.write("Given format"+r);

document.write("<br />")

for (i=0;i<=4;i++)
{

for(j=0;j<=4;j++)

{

if (r[i]<=r[j])
{

t=t+1;

}

}

if (t==1)
{
b[4]=r[i];
document.write(" Highest no"+b[4]+"<br /> ");

}

else if(t==2)
{
b[3]=r[i];
document.write("second highest no"+b[3]+"<br /> ");

}

else if(t==3)
{
b[2]=r[i];
document.write("Third highest no"+b[2]+"<br /> ");

}

else if(t==4)
{

b[1]=r[i];
document.write("Fourth highest no"+b[1]+"<br /> ");

}

else if(t==5)
{
b[0]=r[i];
document.write("Least no"+b[0]+"<br /> ");

}

t=0;
}

document.write("Output in Ascending order:")

for(i=0;i<=4;i++)

{
document.write(b[i]+" ");
}

</script>

Prog for printing this kind of letters \/ and how to use gotoxy function like space

/*Below program for printing blank spaces and letters like 'V'

#include<stdio.h>
#include<conio.h>

main()
{
int i,j;

clrscr();

for(i=1;i<=6;i++)
{

for(j=1;j<=i;j++)

{
if(j==i)
{
printf("\n");
gotoxy(i,j);
printf("*");
}

}
}
