How to solve this question? using C language..

LanzSlumber

Write a simple program where the input is a letter of the alphabet and the output is an upside down triangle as shown below:

input : E
output : ABCDE
             ABCD
             ABC
             AB
             A

takde yg boleh jawab ke?

juwaini

Pakai C++ boleh?

LanzSlumber

ok boleh... sy dah wat tp tak jadi...

ni cth yg saya wat, tp tak jadi..

#include <iostream>
#include <stdlib.h>
#include <stdio.h>
using namespace std;

int main ()
{
    char E;
   
    printf ( "Enter capital 'E': " );
    scanf ( "%c", &E );
   
    for (int c = 5; c > 0; c -- )
    {
        for ( int d = 1; d <= c; d ++ )
        {
            printf ("%c", ++E );
        }
        printf ( "\n" );
    }
   
    printf ( "\n\n" );
   
    system ( "pause" );
   
    return 0;
}

OK siap...

1. 
   
2. #include <iostream>
   
3. 
   
4. using namespace std;
   
5. 
   
6. int main()
   
7. {
   
8.     char ch;
   
9.     int ord;
   
10. 
    
11.     cout << "Please enter 'E': ";
    
12.     cin >> ch;
    
13. 
    
14.     for (int j=0; j<=4; j++)
    
15.     {
    
16.         for (int i=4; i>=j; i--)
    
17.         {
    
18.             ord = static_cast<int>(ch) - i;
    
19.             cout << static_cast<char>(ord);
    
20.         }
    
21.         cout << endl;
    
22.     }
    
23. 
    
24. return 0;
    
25. }
    

Copy the Code

thanks juwaini ...

your answer has give me this idea...

#include <iostream>
#include <stdlib.h>
#include <stdio.h>
using namespace std;

int main ()
{
    char E;
   
    printf ("Enter capital 'E': ");
    scanf ("%c", &E );
   
    for (int c = 0; c < 5; c ++ )
    {
        for (int d = 4; d >= c; d -- )
        {
            printf ("%c", E - d );
        }
        printf ("\n\n" );
    }
   
    system ("pause" );
   
    return 0;
}

am just improvise it...

Sintaks tak penting. Yang penting paham dia punya logik je...

BTW, kalau ko pure C programmer, line "using namespace std" tu tak perlu lagi dah... Yang tu cuma untuk C++ je.

jawapan  tu tak lengkap.
kalau php la
<?php

1. 
   
2. <?php
   
3. 
   
4. $request='N';
   
5. $continue=0;
   
6. foreach (range('Z', 'A') as $letter) {
   
7.    //echo $letter;
   
8.    if($letter == $request) {
   
9.         $continue=1;
   
10.    }
    
11.    if($continue==1) {
    
12.     $str.=$letter;
    
13.    }
    
14. }
    
15.   $str_array =str_split($str);
    
16.   $str_array = array_reverse($str_array);     
    
17.   echo  implode('',$str_array);
    
18. ?>
    
19. ?>

way 1
1. create an array  contain A to Z
2.  loop the array until X
3.  break the loop .
4.  print reverse order of the val
way 2
1.create an array contain Z to A
2. loop the array until X
3.  Create a variable which can catch value after found event
4.  print value
