10 pts #7 Write a full program to do this.
Submit: code & runs

NOTE: For this question, the books says chech the first 6 characters of string one. Since "Frank" is only 5, I am assuming they want the 6th
character to be checked as the carrige return. Hence why when Frank is compared to Franklyn, it comes as false because the program compares
Frank(\0) to Frankl

FILE 1 (MAIN)

#include "CommonInfo.h"




int main()
{
    char string1[] = {"Frank"};
    char string2[] = { "Franklyn" };

    

    

    if (checkIfEqual(string1, string2)) {
        
        cout << "Same";

    
    }
    else {
    
        cout << "Different";
    
    }


}

FILE 2 (Functions)

#include "CommonInfo.h"

bool checkIfEqual(char string1[], char string2[]) {

    for (int x = 0; x < 6; x++) {

        if (string1[x] != string2[x]) {


            return false;

        }

    }
    return true;

}


FILE 3(Header)
