# C program to print pyramid using star or any other character

### C program to print a pyramid using star or any other character :

In this tutorial, we will learn how to print a pyramid using star ’*’ or any other character using ‘C programming language’. The user will input the height of the pyramid and we will print the pyramid equal to that height . It will look like as below :

``````    *
***
*****
*******
*********``````

The height of this pyramid is 5. So, how is it working ?

### How the program works :

We are printing blank space and * to print this full pyramid. The height of the pyramid is 5. If we change the program to print # instead of space, it will be look like :

``````####*
###***
##*****
#*******
*********``````

Think # as space and height is 5 . Analysing the above pyramid, we can find out that :

1. First line : four # and one *. That means we will print four spaces and one * for the first line if height is 5.
2. Second line : three # and three *. That means we will print three spaces and three * for the second line if height is 4
3. From the above two lines , it is clear that we will print space for n times. n is the row number for the pyramid. For the first row, we are printing # for one time, for the second row, we are printing # two times etc.
4. After printing space, we will print * for 2*n - 1 time. Where n is the row number. For the first row, we are printing 2 * 1 - 1 = 1 time. For second line, we will print * for 2 * 2 - 1 = 3 times etc.
5. To print the full pyramid, we will use one for loop. The loop will run from 1 to the height of the pyramid. Using the above two method, we will print the full pyramid.

### C program :

``````#include

int main()
{
int i, j, height;

printf("Enter height of the pyramid : \n");
scanf("%d", &height);

for(i=1; i<=height; i++)
{

for(j=i; j<height; j++)
{
printf(" ");
}

for(j=1; j<=(2*i-1); j++)
{
printf("*");
}

printf("\n");
}

return 0;
}``````

### Example Output :

``````Enter height of the pyramid :
5
*
***
*****
*******
*********

Enter height of the pyramid :
10
*
***
*****
*******
*********
***********
