string compare

sfeng12 · #1 03-May-2004, 16:58

let say,

you have
array=["how", "kick", "you"]
...code here.....
.
.
.

the program does is when user enter a string, such as "how he kick you"
then the program will compare the each word on the string to the array, check if they match.
like, it take "how" from string the user enter, and compare to array, see if it match to the array. if yes, check next word "he", so on.

anyone can help how to start programming this?

There are many ways to solve this task. Have you tried *anything*? Honestly, I don't really want to help you, because given your post, you don't appear to have actually attempted to solve the problem on your own. On the contrary, I do want to help you because this problem could drive you insane! You simply have to copy the user's input into a new array that looks like the one you already have, then compare each element in the input array to each other element in the first array for equality. If you are using an array of string objects, it may be useful for you to know that array subscripts work with string objects.

i simply code 1 for you
duno is that what you want or not

CPP / C++ / C Code:

#include <cstdlib>
#include <iostream>
#include <ctype.h>
using namespace std;
void convertToLowercase (char *sPtr)
{
 while (*sPtr != '\0')
 {
  if (*sPtr >= 'A' && *sPtr <= 'Z')
  {
   *sPtr = tolower(*sPtr);
  }
  ++sPtr;
 }
}
int main()
{
char how[4]="how";
char kick[5]="kick";
char you[4]="you";
char read[44];

cin.getline(read,44);
convertToLowercase(read);

string a=how;
string b=kick;
string c=you;

string full=a+" "+b+" "+c;

if(full==read)
cout<<"same"<<endl;
else
cout<<"Not same"<<endl;
    system("pause");
    return 0;
}
