Array correction

[cyber-noob]

Hi
Please help me. I have done these program please correct where is the error. I tried to find out but I have not yet got the correct error. This is the code to find union of two arrays.

main()
{
int x[5]={1,3,4,6,8},b[5]={2,4,5,6,10},i,d,k,c[10];
for(i=0;i<5;i++)
{
for(d=0;d<5;d++)
{
if(x[i]!=b[d])
{
c[k]=x[i];
k++;
}
else
c[k]!=x[i];
}
}
strcat(b,c);
printf("%s",b);
}

This is the code to find intersection of two arrays

main()
{
int x[5]={1,3,4,6,8},b[5]={2,4,5,6,10},i,d,k,c[10];
for(i=0;i<5;i++)
{
for(d=0;d<5;d++)
{
if(x[i]==b[d])
{
c[k]=x[i];
k++;
}
else
c[k]!=x[i];
}
}
printf("%s",b);
}

Please check were is the error. Thanks in advance.

Hi
I think that in both of your programs you have used variable "k" which is been not initialized to zero or any number. And one more thing that i doubt is that your strcat() method will work on int data type or not. Make these two changes in your program and see if the program is working fine. If it does not then do post back.

Hi
I have read both of your code and I am suggesting some to the changes to you. Many be then this will work.
In your union program
you have to initialize k = 0
Then there is no need for this part

else
c[k]!=x[i];

The following part of the code will not work as b is not a string. b is array of integers.

strcat(b,c);
printf("%s",b);

In your intersection program
you have to initialize k = 0
Then there is no need for this part

else
c[k]!=x[i];

This part of the code will not print intersection because the intersection values are saved in array c. so you have to print the array c.

printf("%s",b)
