C program arrow star pattern

The method used below is as follows:

Enter in integer form .
Then print n spaces and n asterisks.
Decrease until n>1.
Now increment until n.
And print spaces and asterisks in increasing order.

Algorithm

Start In function int arrow(int num) Step 1-> declare and initialize i, j Step 2-> Loop For i = 1 and i <= num and i++ Loop For j = i and j < num and j++ Print a space Loop For j = i and j <= num and j++ Print "*" Print newline Step 3-> Loop For i = 2 and i <= num and i++ Loop For j= 1 and j < I and j++ Print a space Loop For j = 1 and j <= i and j++ Print "*" Print newline In function int main() Step 1-> declare and initialize num = 4 Step 2-> call arrow(num)

Example

Demonstration

#include  // arrow function int arrow(int num) { int i, j; // Prints the upper part of the arrow for (i = 1; i <= num; i++) { // to print the spaces for (j = i; j < num; j++) { printf(" "); } // to print the * for the pattern for (j = i; j <= num; j++) { printf("*"); } printf("
"); } // Prints lower part of the arrow for (i = 2; i <= num; i++) { // to print the spaces for (j = 1; j < i; j++) { printf(" "); } // to print the * for the pattern for (j = 1; j <= i; j++) { printf("*"); } printf("
"); } return 0; } int main() { // get the value from user int num = 4; // function calling arrow(num); return 0; }
