Alphabet Pattern (or) Character Pattern8 Program in C

Write "C"  Program to print below Alphabet Pattern8 (or) Character Pattern8:

To understand this example, you should have knowledge of the following topics:
·     C if Else Statement
·     C For loop
·     C programming operators
C Character pattern8 program using For loop:
#include<stdio.h>
void main() { int i,j,k = 1, n; printf("Enter the number of lines\n"); scanf("%d",&n); for(i = 1;i <= n;i++) { for(j = 1;j <= i;j++,k++) { printf("%c",(char)(k+64)); } printf("\n"); } }


Output:
Enter the number of lines 5
A
BC
DEF
GHIJ
KLMNO
Explanation:
  • First four integers "i", "j", "k", "n"  are declared of type int.
  • Then in the First for loop “i” value is initialized with a value of "1". 
  • Now “i” value is checked with the condition "i <= n" (where "n" value is given through Keyboard). If the condition is True loops enter into second for loop.
  • Now the loop enters into second for loop and checks the condition j <=i. Where "j = 1". and the condition is True.
  • Now prints the " Alphabet". Print up to second for loop condition becomes False.
  • When the value of "i"  becomes greater than "n" value the program terminates.
