tell me about "c" conditional structures?

Answer 1

There is an interesting alternative to certain kinds of conditional statement which are mostly the same but with just a small difference. You can write a conditional assignment like:

a = b + c + (e < 0 ? f : g) + h;

which means:

if (e < 0) a = b + c + f + h;
else a = b + c + g + h;

Some experienced C programmers say this is the most ghastly feature of C and you should hardly ever use it. Others claim that it is the very thing for keeping your code compact, non-repetitive and instantly understandable. So, make up your own mind.

Answer 2

There are two types of conditional structure 1) Selection and 2) Iteration or Repetition.
the "if" structure is used when one alternative is to be chosen from one or two alternatives and "switch-case" is to be chosen when only one alternative is to be chosen from multiple alternatives. Their general forms are :
1) if ( cond_exp )
statement(s)
[ else
statement(s) ]
Example : if (num1>0) printf("%d is positive", num1);
2) switch ( expression)
{case item1 : action1; break;
case item2 : action2;break
....
case item3: action3; break;
default : default action;
}
Example : switch (choice)
{ case 'C' : printf('Circle");
case 'R' : printf("Rectangle");
default : printf("Invalid Choice");
}

For repetition or loop C provides
1) for (initi_expr; cond_expr; modi_expr)
statement(s)
Example : for (i=1;i>=10;i++) printf("%d", i);

2) while (cond_expr)
statement(s)
Example : while ( i<=10) { printf("%d",i); i++; }

3) do
statement(s)
while (cond_expr);
Example : do { printf("%d",i); i++; } while (i<=10);

Answer 3

Condition statements in c are of three types they r (if,do,while) they r used to check a specific condition or to verify;
eg:
if(x<5)
do the following
.........
else
don't do it

Answer 4

C
C is a general purpose Programming Language. C has proven to be a pleasant, powerful, and versatile language for a wide variety of Programs. Many of the modern languages like C++, Visual C++, Java, JavaScript, etc. are based on C Language. Therefore, not knowing this Language is considered a handicap. 90% of UNIX Operating System is written in C Language.

SALIENT FEATURES

C is a general purpose Structured Language that is powerful, efficient and compact.
C is combination of High level language and Assembly language that's why it's good for man & assembler.
C is a robust language whose rich set of built-in function and operator can be used to write any complex program.
C is portable language.
C provides a variety of data types.
In addition, there is a hierarchy of derived data types created with pointers, arrays, structures and unions.
Programming in C is efficient & fast because of its datatypes and various operator.

C++ is a Object Oriented Programming Language that is powerful, efficient and compact. It includes concepts like Polymorphism, Dynamic Binding, Data hiding, Operator encapsulation and inheritance, which are to observed in C. User defined Objects (instances) can be reused with and without modifications to generate newapplication. This reduces coding to greater extends.
