array ?

[silhoutte75]

I mistakenly posted this code in wrong forum. Could anyone help me. I am stuck trying to evaluate the elements of two different arrays and determine whether or not they are equal.

I get my program to compile but it is not reading the individual elements of my array. I'm stuck and need some help please.

Thank You,

#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

any help is appreciated.

if (!(setA[i] == setB[i]))
That's what you want equality and not assignment.

It worked. One other question how might I get my if statement to stop after one false statement.

It worked. One other question how might I get my if statement to stop after one false statement.

There are several ways:
You can put a break in the loop when you have determined the "not equal".
You can use a variable that you set to "true" when you start ["assume equal until proven unequal"], then set it to "false" when you find it unequal, and add this variable to the loop conditin.

You may also want to move your printf("TRUE") out of the loop, as it's got the same problem as your printf("false");

I have attempted several different steps to get just one true or false. None of my methods have successed. What am I doing wrong.

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

and I've tried:

if (setA[i] != setB[i}
 {
   printf ( "false.\n\n");
 }
else
  printf ("True.|n\n");

and

for(sum = 0, i = 0; i < 10; i++);
     if (setA[i] == setB[i]);
      {
         scanf ("%d", &i);
         sum += i;
         printf ("True.\n\n");
      }
    else
       printf ("False.\n\n");

Please help me understand better.
Thank you.

Just use this

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