Alphabet Pattern 5 (or) Character Pattern 5 Program in C

Write "C"  Program to print below Alphabet Pattern 5 (or) Character Pattern 5:

To understand this example, you should have knowledge of the following topics:

·     C if Else

·     C For loop

·     C programming operators

C Character pattern program using For loop:

#include<stdio.h> 
void main()
{
    int i,j,k,n;
    printf("Enter the number of lines\n");
    scanf("%d",&n);
    for(i=1;i<=n;i++)
    {

        k = i;
        for(j=1;j<=i;j++,k++)
        {
            printf("%c",(char)(k+64));
        }
        printf("\n");
    }
}

Output:

Enter the number of lines
5
A
BC
CDE

DEFG

EFGHI

Explanation:

• The first four integers "i", "j", "k", and "n" are declared of type int.
• Then in the First for loop “i” value is initialized with a value 1.
• Now “i” value is checked with the condition i < n that is (where n value is given through Keyboard). If the condition is True loops enter into second for loop.
• Now the loop enters into the 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 the "n" value the program terminates.
