Explain the difference between text mode and binary mode files



Streams can be classified into two types: 

1. text streams and
2. Binary streams

1.Text streams are interpreted, with a maximum length of 255 characters. With text streams, carriage return/line feed combinations are translated to the newline n character and vice versa.

2. Binary streams are uninterrupted and are treated one byte at a time with no translation of characters. a text stream would be used for reading and writing standard text files, printing output to the screen or printer, or receiving input from the keyboard. A binary text stream would typically be used for reading and writing binary files such as graphics or word processing documents, reading mouse input, or reading and writing to the modem.

Difference between Structure and Union


Sr No.
Structure
Union

1
Structure is user defined data type
Which store a record with multiple value
Union is also a user defined data type
But only one member can be saved at a time
2
Separate space was allocated for each member of structure
A common space allocated for all member

3
All members can be initialized at ones.
                                                                   
Only one member can be initialized at a time.

4
Total memory allocated by a structure variable is equal to number of member allocated space.
Space allocated equal to higher member allocated space.
5
One can provide and used all member data simultaneously.
Only one member value can be read or write at ones.
6
Uses rate of structure is higher due to separate space allocation for each member.
Uses rate is lower than structure due common space allocation.


7
You can updated previous value of any member without losing other member data
If a member initialized and another attempt for change value of other member lead loss of previous value.

struct stu
{

     printf("\nSize of Structure %d",sizeof(ob1));
     printf("\n\tRoll=%d\n\tName=%s\n\tCity=%s",ob1.roll,ob1.nm,ob1.city);
     ob2.roll=101;
     printf("\nSize of Union\t %d",sizeof(ob2));
     printf("\nUnion Roll %d",ob2.roll);
     strcpy(ob2.nm,"Girfa");
     printf("\nValue Loss due to Union  %d",ob2.nm);
