Question

C++ Program Pointers and Classe

Write two versions of a string-comparison function. The functions take a third argument specifying the number of characters in each string to compare. These functions should act like function 'strncmp'. The first version should use array subscripting, and the second should use pointers and pointer artithmetic.

Please use the template below and write lines of code for where it asks for it. (In the /* */ comment sections)

Explanation / Answer

#include <iostream>

using namespace std;

int stringCompare1(char s1[], char s2[]);
int stringCompare2(char s1[], char s2[]);

int main(){
   char string1[100], string2[100];
   cout << "Enter two strings: ";
   cin >> string1 >> string2;

   cout << "The value returned from stringCompare1( "" << string1 << "", "" << string2 << "") is "
   << stringCompare1(string1, string2) <<
   " The value returned from stringCompare2( "" <<
   string1 << "", "" << string2 << "") is " << stringCompare2(string1, string2) << endl;

   return 0;
}

int stringCompare1(char s1[], char s2[]){
   int index;
   for(index = 0; ; ++index){
       if(s1[index] == '' && s2[index] == ''){
           return 0;
       }
       else if(s1[index] < s2[index]){
           return -1;
       }
       else if(s1[index] > s2[index]){
           return 1;
       }
   }
}

int stringCompare2(char s1[], char s2[]){
   for(; ; s1 += 1, s2 += 1){
       if(*s1 == '' && *s2 == ''){
           return 0;
       }
       else if(*s1 < *s2){
           return -1;
       }
       else if(*s1 > *s2){
           return 1;
       }
   }
}
