C Program to print Pattern 1 * * * * * * * * * * * * * * *

Write a C program to print a left-aligned right triangle of stars.

Use two nested loops: an outer loop for rows (i) and an inner loop for columns (j).
Run the outer loop from i = 1 to 5.
Run the inner loop from j = 1 to i.
Inside the inner loop, print a star *.
After the inner loop finishes, print a newline \n to move to the next row.

main.c

#include<stdio.h>

int main( ) {
 int i ,j;
 for(i=1;i<=5;i++) {
  for(j=1;j<=i;j++) {
   printf("*");
  }
  printf("\n");
 }
 return 0;
}

Explanation of the Program

Pattern programs are the best way to understand Nested Loops.
The outer loop controls how many rows the pattern will have. The inner loop controls what is printed on each individual row.
Because the inner loop condition is j <= i, the 1st row prints 1 star, the 2nd row prints 2 stars, and so on.

Time Complexity O(n^2) - Where n is the number of rows.

Space Complexity O(1)
