what type of questions they will ask.how to face the interview.one more thing is my post gradutaion degree is MBA.with this degree their is any problem to work in multimedia field.

You haven’t said anything at all about the KIND of multimedia creativity that this employer is looking for, what the company produces or what their core values are. In other words, technical talent alone is often not enough to land professional positions in creative fields.

Anyone can learn software. Learn what the company does, then prepare suitable VISUAL presentation of what MULTIMEDIA TALENT you are READY to CONTRIBUTE to that company.

Of course, relevant experience "already working for so-and-so who also did that" is also a big help.

What I am trying to figure out how to do is to write the binary data to file, then read it out again. The data that is to be written, (in binary), to file is those numbers generated by randomnum() and put in to buffer[]. The numbers in the buffer array are then to be written to file. I however want to be able to then read from the binary file and display the contents. What is happening though is that I get a bunch of symbol charecters written to file and hence the screen. I am wondering how to get back the actual numbers?

void filepointer()
{
FILE * pFile;
int k, i;
char buffer[10];
for (i = 0; i < 10; i++)
{
k = randomnum();
buffer[i] = k;
}
pFile = fopen ( "../Images/myfile.dat" , "wb" );
fwrite (buffer , 1 , sizeof(buffer) , pFile );
fclose (pFile);
return 0;
}
int randomnum()
{
int n;
n = rand(1000);
return n;
}
void analysis()
{
FILE *ab;
ab = fopen("../Images/myfile.dat", "rb");
if ( ab != NULL )
{
char line [ 10 ];
while ( fgets ( line, sizeof line, ab ) != NULL )
{
printf("%s\n ", line);
}
fclose ( ab );
}
else
{
perror ( "The following error occurred: " );
}
}

What I am trying to do is to write the file in an image format such as BIL or bip. Any thoughts?
Thank you Eduardo, unfortunaty though I am getting a "Permission denied" error either method of yours that I use. Any ideas why this is?

Thank you,

The Problem is in Analysis Function You Have Two Option:

With Funciont fgets:

void analysis()
{
FILE *ab;
int index;
ab = fopen("D:/Images/myfile.dat", "rb");
if ( ab != NULL )
{
printf("\n Lectura \n");

char line [ 10];

while (fgets ( line, sizeof(line), ab ) != NULL)
{
for(index=0;index<10;index++)
{
if(line[index]==’\x0′)
{
break;
}
printf(" %d ",(int)line[index]);
}
}
fclose ( ab );
}
else
{
perror ( "The following error occurred: " );
}
}

Or with Fread:

void analysis()
{
FILE *ab;
char number;
ab = fopen("D:/Images/myfile.dat", "rb");
if ( ab != NULL )
{
printf("\n Lectura \n");

fread(&number,sizeof(char),1,ab);
while(!feof(ab))
{
printf(" %d ",(int)number);
fread(&number,sizeof(char),1,ab);
}
fclose ( ab );
}
else
{
perror ( "The following error occurred: " );
}
}
