A string to rotate it by n characters

#1

i tried to solve this question using swapping technique but got wrong output.
int main()
{

char s[30]="hello";
int k;
char ch,x;
cin>>k;
int l=strlen(s);
for(int i=0;i<=l/2;i++)
{

    ch=s[i];
    s[i]=s[i+k];
    s[i+k]=ch;

}

for(int i=(l/2)+1;i<l;i++)
{
     x=s[i];
     s[i]=s[i-k-1];
    s[i-k-1]=x;

}

cout<<s;

}

Hello @Adi,

From next time, please share your code using Online Coding Blocks IDE.
Steps:

  1. Paste your code at https://ide.codingblocks.com/
  2. Save it there.
  3. Share the URL generated.

The way you have to send it, introduces syntax errors to it.

Now, coming back to your code:
Can you explain the logic you are trying to implement?
It would not work.

  1. The first loop will access the index>length(string) for k>len/2
  2. The second loop will shift the elements by k-1 positions to left.
