I am having trouble with the "for loop" of a 32 bit Adder program. I am suppose to take 2 arrays of 32 bits and sum them together.

The 2 errors I get are on line 37 and 38 called "called object is not in function".

I don't know how to implement the for loop. Can anyone help or point me in the right direction?

```
#include "stdio.h"
#include "stdlib.h"
int sum(int x[], int y[], int c);
int carryIn(int d[], int e[], int f);
int main (void){
int a[32], b[32], sum[32];
int x,y,c;
int d,e,f;
int i;
printf("Enter 32 bits: ");
scanf("%d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d",
&a[31], &a[30], &a[29], &a[28],
&a[27], &a[26], &a[25], &a[24], &a[23], &a[22], &a[21], &a[20], &a[19], &a[18], &a[17],
&a[16], &a[15], &a[14], &a[13], &a[12], &a[11], &a[10], &a[9], &a[8], &a[7],
&a[6], &a[5], &a[4], &a[3], &a[2], &a[1], &a[0] );
printf("Enter 32 bits: ");
scanf("%d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d %d",
&b[31], &b[30], &b[29], &b[28],
&b[27], &b[26], &b[25], &b[24], &b[23], &b[22], &b[21], &b[20], &b[19], &b[18], &b[17],
&b[16], &b[15], &b[14], &b[13], &b[12], &b[11], &b[10], &b[9], &b[8], &b[7],
&b[6], &b[5], &b[4], &b[3], &b[2], &b[1], &b[0] );
int carryIn=0; //Initialize 0 to carryIn
for(i=0;i<32;i++){
sum(a[i],b[i],carryIn); //compute the sum
carry(a[i],b[i],carryIn); // compute the carryover
sum[i]= sum(a[i],b[i],carryIn); //put sum in the sum[] array
carryIn = carry(a[i],b[i],carryIn);
}
system("PAUSE");
return 0;
}
int sum(int x[], int y[], int c){
return ((!x && !y && c)||
(!x && y && !c) ||
(x && !y && !c) ||
(x && y && c));
}
int carry(int d[], int e[], int f){
return ((!d && e && f) ||
(d && !e && f) ||
(d && e && !f) ||
(d && e && f));
}
```
