C program to print patterns of numbers,alphabets and stars in a pyramid shape

• We can print *'s  in pyramid pattern using C programming language.
• We can also print  patterns of numbers and alphabets using C program.
• Now Check below program that how to print pyramid pattern of * using C program using for loop.
• C program to print patterns of numbers and stars in a pyramid shape

Program #1 : Write a C program to print pyramid pattern of numbers using for loop.

1. #include <stdio.h>
2. #include <stdlib.h>
3.  
4. int main(){
5.     
6.    int i, j, rows;
7.  
8.     printf("Enter number of rows: \n");
9.     scanf("%d",&rows);
10.  
11.     for(i=1; i<=rows; ++i)
12.     {
13.         for(j=1; j<=i; ++j)
14.         {
15.             printf("* ");
16.         }
17.         printf("\n");
18.     }
19.         
20.    getch();
21.     
22. }

   
Output:

 Program #2 : Write a C program to print pyramid pattern of numbers using for loop.

1. #include <stdio.h>
2. #include <stdlib.h>
3.  
4. int main(){
5.     
6.    int i, j, rows;
7.  
8.     printf("Enter number of rows to print pyramid numbers pattern \n ");
9.     scanf("%d",&rows);
10.  
11.     for(i=1; i<=rows; ++i)
12.     {
13.         for(j=1; j<=i; ++j)
14.         {
15.             printf("%d ",j);
16.         }
17.         printf("\n");
18.     }
19.         
20.    return 0;
21.     
22. }

Output:

1. Enter number of rows to print pyramid numbers pattern
2.  10
3. 1
4. 1 2
5. 1 2 3
6. 1 2 3 4
7. 1 2 3 4 5
8. 1 2 3 4 5 6
9. 1 2 3 4 5 6 7
10. 1 2 3 4 5 6 7 8
11. 1 2 3 4 5 6 7 8 9
12. 1 2 3 4 5 6 7 8 9 10

  
Program #3 : Write a c program to print patterns of numbers and alphabets

1. #include <stdio.h>
2. #include <stdlib.h>
3.  
4. int main(){
5.     
6.    int i, j;
7.     char input, alphabet = 'A';
8.  
9.     printf("Enter the uppercase character you want to print in last row: ");
10.     scanf("%c",&input);
11.  
12.     for(i=1; i <= (input-'A'+1); ++i)
13.     {
14.         for(j=1;j<=i;++j)
15.         {
16.             printf("%c", alphabet);
17.         }
18.         ++alphabet;
19.  
20.         printf("\n");
21.     }
22.     
23.     getch();
24.     
25. }

Output:

1. Enter the uppercase character you want to print in last row:
2.  I
3. A
4. BB
5. CCC
6. DDDD
7. EEEEE
8. FFFFFF
