the basic concepts of OOP's are
1.class- it is a collection of variables and methods
2.odjects- it is the run time entity(it is same as real
world objects)
3.data abstraction and encapsulation-essential features of
data not including the background details
4.polymorphism-same name with more than one form
5.inheritance-concept of acquiring the base class properties
there are 5 types of inheritance
1.single inheritance
2.multiple inheritance
3.multilevel inheritance
4.hierarchical inheritance
5.hybrid inheritance
6.dynamic binding- data bind at runtime
7.message passing-communicating information with one another

#include #include #include #include void select(char *items, int count); int main(void) { char s[255]; printf("Enter a string:"); gets(s); select(s, strlen(s)); printf("The sorted string is: %s.\n", s); getch(); return 0; } void select(char *items, int count) { register int a, b, c; int exchange; char t; for(a = 0; a < count-1; ++a) { exchange = 0; c = a; t = items[ a ]; for(b = a + 1; b < count; ++b) { if(items[ b ] < t) { c = b; t = items[ b ]; exchange = 1; } } if(exchange) { items[ c ] = items[ a ]; items[ a ] = t; } } } design an algorithm for Selection Sort

write a code for this. serial_number contained in the header of the file will be read , if this serial number is less than a previous serial number within a successfully processed file, or is the same as another serial number within a successfully processed file, or if the field contains anything other than 7 digits, then the file must error with the reason ‘Invalid SERIAL_NUMBER’.
