You should have knowledge of the following topics in c programming to understand these programs:
- C
main()function - C
forloop statement - C
ifcondition statement - C
incrementoperator - C
printf()function
1. C program to print inverted pyramid pattern of Stars
// C program to print inverted pyramid pattern of Stars
#include <stdio.h>
int main() {
int rows, j;
printf("Enter the number of rows: ");
scanf("%d", &rows);
if (rows > 0) {
printf("\n");
for (int i = rows; i >= 1; i--) {
for (int leet = 0; leet < rows - i; leet++)
printf(" ");
for (j = i; j <= 2 * i - 1; j++)
printf("* ");
for (j = 0; j < i - 1; j++)
printf("* ");
printf("\n");
}
}
return 0;
}
Output
Enter the number of rows: 5

2. C program to print inverted pyramid pattern of Numbers
// C program to print inverted pyramid pattern of Numbers
#include <stdio.h>
int main() {
int rows, j, number = 1;
printf("Enter the number of rows: ");
scanf("%d", &rows);
if (rows > 0) {
printf("\n");
for (int i = rows; i >= 1; i--) {
for (int leet = 0; leet < rows - i; leet++)
printf(" ");
for (j = i; j <= 2 * i - 1; j++) {
if (number > 10)
printf("%d ", number++);
else
printf("%d %c", number++, ' ');
}
for (j = 0; j < i - 1; j++) {
if (number > 10)
printf("%d ", number++);
else
printf("%d %c", number++, ' ');
}
printf("\n");
}
}
return 0;
}
Output
Enter the number of rows: 5
1 2 3 4 5 6 7 8 9
10 11 12 13 14 15 16
17 18 19 20 21
22 23 24
25
3. C program to print inverted pyramid pattern of Alphabets
// C program to print inverted pyramid pattern of Alphabets
#include <stdio.h>
int main() {
int rows, j, alphabet = 'A';
printf("Enter the number of rows: ");
scanf("%d", &rows);
if (rows > 0) {
printf("\n");
for (int i = rows; i >= 1; i--) {
for (int leet = 0; leet < rows - i; leet++)
printf(" ");
for (j = i; j <= 2 * i - 1; j++)
printf("%c ", alphabet);
for (j = 0; j < i - 1; j++)
printf("%c ", alphabet);
alphabet++;
printf("\n");
}
}
return 0;
}
Output
Enter the number of rows: 5
A A A A A A A A A
B B B B B B B
C C C C C
D D D
E
Explanation
In these programs, we have taken input 5 from the user of the pattern then this input passes to loop iterations.
By following perspective logic to print the inverted pyramid pattern.
