Write a C program to print V star pattern using for loop.
#include <stdio.h>
int main()
{
int rows;
printf("Enter V Shape Star Pattern Rows = ");
scanf("%d", &rows);
printf("Printing V Shape Star Pattern\n");
for (int i = 1; i <= rows; i++)
{
for (int j = 1; j <= i; j++)
{
printf("*");
}
for (int k = 1; k <= 2 * (rows - i); k++)
{
printf(" ");
}
for (int l = 1; l <= i; l++)
{
printf("*");
}
printf("\n");
}
}

C program to print the V star pattern of stars using a while loop
#include <stdio.h>
int main()
{
int i, j, k, l, rows;
printf("Enter V Shape Star Pattern Rows = ");
scanf("%d", &rows);
printf("Printing V Shape Star Pattern\n");
i = 1;
while (i <= rows)
{
j = 1;
while (j <= i)
{
printf("*");
j++;
}
k = 1;
while (k <= 2 * (rows - i))
{
printf(" ");
k++;
}
l = 1;
while (l <= i)
{
printf("*");
l++;
}
printf("\n");
i++;
}
}
Enter V Shape Star Pattern Rows = 13

This example uses the do while loop to print the alphabetical V shape star pattern.
#include <stdio.h>
int main()
{
int i, j, k, l, rows;
printf("Enter V Shape Star Pattern Rows = ");
scanf("%d", &rows);
printf("Printing V Shape Star Pattern\n");
i = 1;
do
{
j = 1;
do
{
printf("*");
} while (++j <= i);
k = 1;
while (k <= 2 * (rows - i))
{
printf(" ");
k++;
}
l = 1;
do
{
printf("*");
} while (++l <= i);
printf("\n");
} while (++i <= rows);
}
Enter V Shape Star Pattern Rows = 16

In this example, the ShapeVPattern function allows entering any character and prints the alphabetical V pattern of a given character.
#include <stdio.h>
void ShapeVPattern(int rows, char ch)
{
for (int i = 1; i <= rows; i++)
{
for (int j = 1; j <= i; j++)
{
printf("%c", ch);
}
for (int k = 1; k <= 2 * (rows - i); k++)
{
printf(" ");
}
for (int l = 1; l <= i; l++)
{
printf("%c", ch);
}
printf("\n");
}
}
int main()
{
int rows;
char ch;
printf("Enter Character for V Pattern = ");
scanf("%c", &ch);
printf("Enter V Shape Star Pattern Rows = ");
scanf("%d", &rows);
printf("Printing V Shape Pattern\n");
ShapeVPattern(rows, ch);
}
Enter Character for V Pattern = $
Enter V Shape Star Pattern Rows = 19
