In this tutorial, we will learn and code alphabet patterns in C programming language specifically the Half pyramid of alphabets in C programming. However, in this tutorial, we will create a pyramid character pattern in C using for loop. So you may go through the following topic in C.
Pattern 1: C program for character/alphabet.
This program asks for the alphabet till which you want to print.
Enter the character till which you want to print in uppercase: F
A
B B
C C C
D D D D
E E E E E
F F F F F F
Source code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | #include <stdio.h> int main() { int i, j; char ch, alphabet = 'A'; printf("Enter the character till which you want to print in uppercase: "); scanf("%c", &ch); for (i = 1; i <= (ch - 'A' + 1); ++i) { for (j = 1; j <= i; ++j) printf("%c ", alphabet); ++alphabet; printf("\n"); } return 0; } |
Pattern 2: C program for character/alphabet.
This program asks the user for the number of rows that you want.
Enter the no. of rows: 6
