Introduction
In this article, I have shared the list of all Star (*) pattern programs in the c programming language. We will learn to create different patterns or a geometrical shape such as square, triangle, etc. To understand these C programming examples, you should have the knowledge C programming topics such as C for Loop, C if .else Statement, C while and do…while Loop, C break and continue statement.
I have used Code:: Blocks IDE for debugging purposes. But you can use any C programming language compiler as per your availability.
1. C program to print right Angled triangle star pattern
#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;
}
2. C program to print mirrored right triangle star pattern
#include <stdio.h>
int main()
{
int i, j, k;
for(i=5;i>=1;i--)
{
for(j=1;j<i;j++)
{
printf(" ");
}
for(k=5;k>=i;k--)
{
printf("*");
}
printf("\n");
}
return 0;
}
