C language - Patterns Display - 005 #coding #correctcoding #programming #education

Building below pattern according to the given input size in c language.
Helps for people who just entered into the programming world and needing to improve their logical knowledge.

Code: (Before execution, replace < and > with lessthan and greaterthan symbols respectively)
#include <stdio.h>

int main() {
int i, j, space;
int rows;

printf("Enter halfth Size:");
scanf("%d", &rows);

// Top half (including middle)
for (i = 0; i < rows; i++) {
// Left stars
for (j = 1; j <= rows - i; j++) {
printf("*");
}

// Middle spaces
for (space = 0; space < 2 * i; space++) {
printf(" ");
}

// Right stars
for (j = 1; j <= rows - i; j++) {
printf("*");
}

printf("\n");
}

// Bottom half (mirror of the top, excluding middle row)
for (i = 0; i < rows; i++) {
// Left stars
for (j = 0; j <= i; j++) {
printf("*");
}

// Middle spaces
for (space = 0; space < 2 * (rows - i - 1); space++) {
printf(" ");
}

// Right stars
for (j = 0; j <= i; j++) {
printf("*");
}

printf("\n");
}

return 0;
}

Output:
Enter halfth Size:10
