Anybody please help me understanding this code in C:

Question

#include<stdio.h>

void main()

{

    int i,j;

    printf(“\n Alphabetical Pattern\n\n”);

    for(i=’A’;i<=’Z’;i++)

    {

        for(j=’A’;j<=i;j++)

        {

            printf(“ %c ”,j);

        }

        printf(“\n”);

    }

}

Answer 1

the following code will produce:-
Alphabetical Pattern

A
AB
ABC
ABCD
.
like this till A-Z

the main code of this program lies in 2 for loops
1. will go from A to Z
2. will go from A to 1st loop's var.
followed by a new line "\n"

line printf(" %c ",j);
will print the value of "j" which is a character type.
thus %c is a format specifier to print a character.

in C printf() is use to print something on screen, like cout in C++.

hope it would help!
