Array question.

I'm stuck. I have written a program to obtain 10 intergers for 2 different array set. I am trying to test the elements of each array and I have gotten stuck. Could someone guide me in the right direction.

Thank You,

Code:

---

#include <stdio.h>
#include <stdlib.h>

int main (void)
{
        //Local Declarations
        int setA[10];
        int setB[10];
        int a = 1;
        int b = 2;

        //Statements
        printf ("Please enter 10 integers for set A values:\n\n");
                for ( int i = 0; i < 10; i++)
                        scanf ("%d", &setA[i]);
               
                printf ("\nPlease enter 10 intergers for set B values:\n\n");
                for ( int i = 0; i < 10; i++)
                        scanf ("%d", &setB[i]);
               


                for (int i = 0; i < 10; i++)
                if (!(setA[i] = setB[i]))
                    printf ("False.\n\n");
                else
                        printf ("True.\n\n");

        system ("PAUSE");
    return 0;
}//main

(Looks more like C than C++)

Your third for loop contains the assignment operator, and not the comparison operator. You're assigning the elements of setB to the elements of setA and then using the negation operator. This means that whenever an element in setB is 0, you'll print "False", otherwise you'll print "True" (after assigning it to the corresponding element in setA).

You probably meant:

Code:

---

if (!(setA[i] == setB[i]))

---

Or better still (because it's easier to understand):

Code:

---

if (setA[i] != setB[i])

---

One more question. How would I get my if statement to stop after one false statement?

Put in a break after the printf statement:

Code:

---

for (int i = 0; i < 10; i++)
    if (!(setA[i] == setB[i]))
    {
        printf ("False.\n\n");
        break;
    }
    else
        printf ("True.\n\n");

... or you could set i to something >= 10 which would stop the loop from executing any further.

Your suggestion worked and it did what I wanted it to do. Is there a way to write this part of the program so that I get only one true or one false statement for the entire run of the program?

If you want to print "True" if the first element matches, put a break after the printf ("True.\n\n"); (within proper braces, of course).

It seems more likely that you want to print "True" when all the values in both arrays match. For that, check if (i==10) after the end of the loop. If it is, you've traversed through the array without finding a different pair of values, so print "True".
