struct emp e;  //a struct of type emp is created, and named e

Code:

e.acc|=ACC_NO;   //mistype, correct is e.acc = variable, not e.acc |= variable

The last line of code shows the dot operator, which is used to access the parts of the struct. Note that "char name" is not an array of char's, but only a single char. To make it longer, you need to make it a char array - char name[40], for example.

Remember that a bunch of char's is not a string, in C. No matter how many there are of them. They are elevated to a string ONLY when they have an End of String marker char, placed as their last value: '\0'.

So: "Frederick" is not a string, but "Frederick\0" is one.

ya, you are right. But, i need help for the second statement in assigning values for structure elements. what's that "or(|)" symbol comes here.

It's used to set specific bits in a variable. Typically used to combine several flags into one variable.
One flag sets bit 1, the next bit 2, and so on.

See it as
SetBit(e.acc, ACC_NO);
