c++ string question?

Question

if I have a string, let's say "something",
How would I use loop and string operations to make it print "something" backward,
like gnihtemos?

This is the last part of my programming HW and I can't figure it out. If anyone can help, I'd appreciate it
Thank you

Answer 1

string a = "something";



for(int i = a.length( ) -1; i >=0; i--)

{

cout << a[i];

}



To do this you do NOT have to use the "cstring" header file. You the string header file as follows:



#include

Answer 2

To do this you must use "cstring" header file. It contains a function called strlen() , so then you can calculate the number of charactors of the string and reverse it by a for loop.

Here's the code:



#include

#include

using namespace std;

int main() {

char name[]="something";





for (int r =strlen(name); 0<=r; r=r-1 )

{ cout << name[r];

}

cout<<"\n";







return 0;

}

Answer 3

get the length of string. after getting length loopfrom last character to first character

Answer 4

Easily done by;



[code]

#include

#include



int main()

{

string reverse;

string test="hellome";

for(int x=test.length()-1; x>-1; x--)

{

reverse+= test.at(x);

cout<
}

cin.get();

return 0;

}

[/code]
