C Program to print right triangle star pattern
In this article, we will discuss the C Program to print the right triangle star pattern
We can display many types of number, star, Alphabet patterns using for.while and do-while loops in C language
In this post, we are going to learn how to print a right triangle star pattern using for, while and do-while loop in C language,
C code to print the right triangle
Program to print right triangle star pattern using for loop
This program allows the user to enter the number of rows and then the program displays the right triangle star pattern using for loop in C language
Program 1
#include <stdio.h>
#include <stdlib.h>
int main()
{
int rows,i,j;
printf("Enter the number of rows:\n");
//input number of rows from user
scanf("%d",&rows);
//entered value store in the rows variable
printf("\n");
for(i=1; i<=rows; i++){//outer for loop
for(j=1; j<=i; j++){//inner for loop
//print i number of star
printf("*");//print ster
}
printf("\n");//move to next line
}
getch();
return 0;
}
When the above code is executed, it produces the following result

Program to print right triangle star pattern using while loop
This program allows the user to enter the number of rows and then the program displays the right triangle star pattern using while loop in C language
Program 1
#include <stdio.h>
#include <stdlib.h>
int main()
{
int rows,i,j;
printf("Enter the number of rows:\n");
//input number of rows from user
scanf("%d",&rows);
//entered value store in the rows variable
printf("\n");
i=1;
while(i<=rows){//outer for loop
j=1;
while(j<=i){//inner for loop
//print i number of star
printf("*");//print ster
j++;
}
printf("\n");//move to next line
i++;
}
getch();
return 0;
}
When the above code is executed, it produces the following result

Program to print right triangle star pattern using do-while loop
This program allows the user to enter the number of rows and then the program displays the right triangle star pattern using do-while loop in C language
Program 1
#include <stdio.h>
#include <stdlib.h>
int main()
{
int rows,i,j;
printf("Enter the number of rows:\n");
//input number of rows from user
scanf("%d",&rows);
//entered value store in the rows variable
printf("\n");
i=1;
do{//outer for loop
j=1;
do{//inner for loop
//print i number of star
printf("*");//print ster
j++;
}while(j<=i);
printf("\n");//move to next line
i++;
}while(i<=rows);
getch();
return 0;
}
When the above code is executed, it produces the following result
