# Print Right Triangle Star Pattern

*

**

***

****

## PREREQUISITE:

Basic knowledge of C language and use of loops.

## ALGORITHM:

1. Take the number of rows as input from the user  and store it in any variable.(‘r‘ in this case).
2. Run a loop ‘r’ number of times to iterate through each of the rows. From i=0 to i<r. The loop should be structured as for( i=0 ; i<r : i++).
3.  Run a nested loop inside the main loop to print the stars in each row of the triangle. From j=0 to j<i. The loop should be structured as for( j=0; j<=i ; j++).
4. In the nested loop print star.
5. In the main loop print a new line.

## Code in C:

```#include<stdio.h>
int main()
{
int i,j,r;      //declaring integer variables i,j for loops and r for number of rows
printf("Enter the number of rows :\n");     //Asking user for input
scanf("%d",&r);     //taking number of rows and saving it in variable r
for(i=0;i<r;i++)     // loop for number of rows
{
for(j=0;j<=i;j++)      // loop for stars per each row
{
printf("*");       //printing stars
}
printf("\n");         // printing newline after each row
}
}```
