Programs to print triangles using *, numbers and characters
Example 1: Program to print half pyramid using *
* * * * * * * * * * * * * * *
#include <stdio.h>
int main()
{
int i, j, rows;
printf("Enter the number of rows: ");
scanf("%d",&rows);
for(i=1; i<=rows; ++i)
{
for(j=1; j<=i; ++j)
{
printf("* ");
}
printf("\n");
}
return 0;
}
Example 2: Program to print half pyramid a using numbers
1 1 2 1 2 3 1 2 3 4 1 2 3 4 5
#include <stdio.h>
int main()
{
int i, j, rows;
printf("Enter the number of rows: ");
scanf("%d",&rows);
for(i=1; i<=rows; ++i)
{
for(j=1; j<=i; ++j)
{
printf("%d ",j);
}
printf("\n");
}
return 0;
}
Example 3: Program to print half pyramid using alphabets
A B B C C C D D D D E E E E E
#include <stdio.h>
int main()
{
int i, j;
char input, alphabet = 'A';
printf("Enter the uppercase character you want to print in last row: ");
scanf("%c",&input);
for(i=1; i <= (input-'A'+1); ++i)
{
for(j=1;j<=i;++j)
{
printf("%c", alphabet);
}
++alphabet;
printf("\n");
}
return 0;
}
Programs to print inverted half pyramid using * and numbers
Example 4: Inverted half pyramid using *
* * * * * * * * * * * * * * *
#include <stdio.h>
int main()
{
int i, j, rows;
printf("Enter the number of rows: ");
scanf("%d",&rows);
for(i=rows; i>=1; --i)
{
for(j=1; j<=i; ++j)
{
printf("* ");
}
printf("\n");
}
return 0;
}
Example 5: Inverted half pyramid using numbers
1 2 3 4 5 1 2 3 4 1 2 3 1 2 1
#include <stdio.h>
int main()
{
int i, j, rows;
printf("Enter the number of rows: ");
scanf("%d",&rows);

{
printf("%d ",j);
}
printf("\n");
}

Programs to display pyramid and inverted pyramid using * and digits
Example 6: Program to print full pyramid using *
* * * * * * * * * * * * * * * * * * * * * * * * *
#include <stdio.h>
int main()
{
int i, space, rows, k=0;

printf("Enter the number of rows: ");
scanf("%d",&rows);
for(i=1; i<=rows; ++i)
{
for(space=1; space <= rows-i; ++space)
{
printf(" ");
++count;
}
while(k != 2*i-1)
{

{
printf("%d ", i+k);
++count;
}
else
{
++count1;
printf("%d ", (i+k-2*count1));
}
++k;
}

printf("\n");
}
return 0;
