Example 1: Half Pyramid of *
* * * * * * * * * * * * * * *
C Program
#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: Half Pyramid of Numbers
1 1 2 1 2 3 1 2 3 4 1 2 3 4 5
C Program
#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: Half Pyramid of Alphabets
A B B C C C D D D D E E E E E
C Program
#include <stdio.h>
int main() {
int i, j;
char input, alphabet = 'A';
printf("Enter an uppercase character you want to print in the 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;
}
Example 4: Inverted half pyramid of *
* * * * * * * * * * * * * * *
C Program
#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 of numbers
1 2 3 4 5 1 2 3 4 1 2 3 1 2 1
C Program
#include <stdio.h>
int main() {
int i, j, rows;
printf("Enter the number of rows: ");
scanf("%d", &rows);

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

Example 6: Full Pyramid of *
* * * * * * * * * * * * * * * * * * * * * * * * *
C Program
#include <stdio.h>
int main() {
int i, space, rows, k = 0;
printf("Enter the number of rows: ");
scanf("%d", &rows);

printf(" ");
}
while (k != 2 * i - 1) {
printf("* ");
++k;
}
printf("\n");

Example 7: Full Pyramid of Numbers
1 2 3 2 3 4 5 4 3 4 5 6 7 6 5 4 5 6 7 8 9 8 7 6 5
C Program
#include <stdio.h>
int main() {

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) {
if (count <= rows - 1) {
printf("%d ", i + k);
++count;
} else {
++count1;
printf("%d ", (i + k - 2 * count1));
}
++k;

count1 = count = k = 0;
printf("\n");
}
return 0;
}
Example 8: Inverted full pyramid of *
* * * * * * * * * * * * * * * * * * * * * * * * *
C Program
#include <stdio.h>
int main() {
int rows, i, j, space;
printf("Enter the number of rows: ");
scanf("%d", &rows);
for (i = rows; i >= 1; --i) {
for (space = 0; space < rows - i; ++space)
printf(" ");
for (j = i; j <= 2 * i - 1; ++j)
printf("* ");
for (j = 0; j < i - 1; ++j)
printf("* ");
printf("\n");
}
return 0;
}
Example 9: Pascal's Triangle
1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 1 5 10 10 5 1
C Program
#include <stdio.h>
int main() {
int rows, coef = 1, space, i, j;
printf("Enter the number of rows: ");
scanf("%d", &rows);
for (i = 0; i < rows; i++) {
for (space = 1; space <= rows - i; space++)
printf(" ");
for (j = 0; j <= i; j++) {
if (j == 0 || i == 0)
coef = 1;
else
coef = coef * (i - j + 1) / j;
printf("%4d", coef);
}
printf("\n");
}
return 0;
}
