for(int i=1; i<=5; i++) {
  for(int j=1; j<=5; j++) {
    printf("*");
  }
  printf("\n");
}
// i=rows(5), j=cols(5)

2. Right Triangle - Most Asked!

for(int i=1; i<=5; i++) {
  for(int j=1; j<=i; j++) {
    printf("*");
  }
  printf("\n");
}
// j<=i - Row number antha stars!
// Row1=1 star, Row2=2 stars...

3. Inverted Right Triangle

for(int i=5; i>=1; i--) {
  for(int j=1; j<=i; j++) {
    printf("*");
  }
  printf("\n");
}
// i 5 nundi 1 varaku reverse

4. Pyramid Pattern - Interview Star!

for(int i=1; i<=5; i++) {
  // Space
  for(int s=1; s<=5-i; s++) printf(" ");
  // Stars - 2*i-1
  for(int j=1; j<=2*i-1; j++) printf("*");
  printf("\n");
}
// Logic: Row1=1 star, Row2=3, Row3=5...
// Formula: 2*i-1 stars

// Type 1:
for(i=1;i<=5;i++){
 for(j=1;j<=i;j++) printf("%d",j);
 printf("\n");
}

// Type 2:
for(i=1;i<=5;i++){
 for(j=1;j<=i;j++) printf("%d",i);
 printf("\n");
}

🎯 Trick for Any Pattern:
1. Rows enta? -> Outer loop
2. Prati row lo columns enta? -> Inner loop
3. Star ah Number ah? -> printf lo
4. Space kavala? -> Inko loop for space
Idi practice cheste 5 mins lo ye pattern aina!
