String/Array Help

[superbeastie]

I suppose the easiet way for me to explain is using some strange C++/pseudo code: :p

#include<stdio.h>
#include<string.h>

int num;
char txt = "string";
char string1[10] = "Test1";
char string2[10] = "Test2";
char string3[10] = "Test3";
....etc....
char string18[10] = "Test";

printf("choose a number from 1 to 18");
scanf("%d", num);
printf("%s",txt+num);

so basicly if the user inputs 9, string 9 will appear, or if the user inputs 2, string 2 will appear.

So How would I go about getting something like that to work in C++.

I hope I explained that well enough, forgive me for my noobishness.

Your code looks more like C instead of C++, but here is the C++ version.

#include <iostream>
#include <string>

//-
using std::string;
using std::endl;
using std::cout;
using std::cin;
//-

int main()
{
  string s1("test 1");
  string s2("test 2");
  string s3("test 3");
  //etc...
  
  string MyStringArray[3]={s1, s2, s3};
  
  cout<<"Choose a number from 1 to 3"<<endl;
  unsigned idx;
  cin>>idx;
  cin.get();
  if(idx > 0 && idx <= 3)
  {
    cout<<MyStringArray[idx-1]<<endl;
  }  
  
  return 0;
}

Here is a C version:

#include <stdio.h>

int main()
{
  char** strings = {"test 1", "test2", "test3", NULL};
  int select = 0;

  printf("Choose a number from 1 to 3\n");
  if(1 != fscanf(stdin, "%d\n", &select))
  {
      printf("Some error happened durign read\n");
      return -1;
  }
  if(select > 0 && select <= 3)
  {
    printf("Your selection: %s\n", strings[select]);
  }  
  return 0;
}

Altho it hasn't been tested, it shuld work right out of the box.

Thankyou for your help both of you, I dont know why I didn;t think of that before, just my noobishness I suppose .

Actually, for an unseasoned programmer, this might be tricky indeed. I am not surprised.

Here's my version in C...

#include <stdio.h>

int main()
{
  char *strings[] = {NULL, "Oggala Booggala!", "Lalalalala", "Huh!?"};
  int select;

  do {
    printf("Choose a number from 1 to 3: ");
    scanf("%i", &select);
  }
  while (select > 3 || select < 1);
  if(select > 0 && select <= 3)
  {
    printf("You selected \"%s\".\n", strings[select]);
  }  
  return 0;
}
