rotate down string

[mike9407]

is it possible to rotate down C string?
exmaple when user input C++ is fun
sample output:

it will be C
............+
..............+

...............i
................s

.................f
..................u
...................n

dot express the blank space

n
any hints to do this?

Use a for loop and iterate through each character. Though you'll need to check for blank spaces.

string str = "C++ is fun";
size_t len = str.length();
for(int i = 0; i < len; i++)
{
     if(str[i] == ' ')
          continue;

     cout << str[i] << endl;
}

I haven't tested this code, but it should work.

what is the continue?i dont understand

Hi mike9407

If I am not wrong then n = number of spaces, right?

#include <fstream.h>
#include <conio.h>
// conio.h is used for clrscr() and getch()

void main()
{
clrscr();
char a[30];
int n,i,j;

cout<<"Enter a string: ";  cin.getline(a,30);
cout<<"Enter the number of spaces: ";  cin>>n; //make sure it is small value
clrscr();

for(i=0;a[i]!='\0';i++)
 { for(j=1;j<=n;j++)
    cout<<" ";
   cout<<a[i]<<endl;
 }
getch();
}

Look at the loop

for(i=0;a[i]!='\0';i++)
 { for(j=1;j<=n;j++)
    cout<<" ";
   cout<<a[i]<<endl;
 }

each time number of spaces are printed then at last the consecutive character of user's string is printed.


Try making a program which gives output if user enters: "C++ is fun"

C  
+  
+  
   
i  
s  
   
f  
u  
n  

Then later you'll be able to make a program like the one you wanted to:)



[EDIT]

continue; skips the current iteration and forces the loop to execute the next one.

for example if you want following output

1  
2  
3  
4  
6  
7  
8  
9  

then you should write

for(int i=0;i<=9;i++)
 { if(i==5)
   continue;
   else 
   cout<<i<<endl;
 }
