Are you preparing for the coding round ? if yes then you must know how to print the patterns. In coding interview interviewer may ask you print any number pattern , alphabet pattern or an character patterns. We recommend you to follow our patterns series so you will feel comfortable with printing patterns. In this blog post you will find set 3 of star patterns.
We recommend you to solve other types patterns as well –
Click on the pattern and you will get redirected to the code.

Code for pattern 1
Java
C++
Java
public class MainClass {
public static void main(String[] args) {
for (int i = 0; i < 5; i++) {
for (int j = 0; j < 5; j++) {
if(j-i>=0)
System.out.print("* ");
else
System.out.print(" ");
}
System.out.println();
}
}
}
C++
#include <iostream>
int main() {
for (int i = 0; i < 5; i++) {
for (int j = 0; j < 5; j++) {
if (j - i >= 0) {
std::cout << "* ";
} else {
std::cout << " ";
}
}
std::cout << std::endl;
}
return 0;
};
