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!
