Call by value in c programming?
Its way of passing arguments to a function.In this method the value of actual arguments(the arguments in the function call)remains unchanged. changes that we make are effected only to the formal arguments.
#include<stdio.h> void modify(int,int);// function prototype. this is given to make the compiler aware that there is a function modify. if we didnt do this a error will be shown. otherwise the function body should be written before the function call
printf("enter two numbers");
modify(a,b);// function call the parameters a and b are actual arguments.
printf(" a and b in the main %d and %d",a,b);
void modify(int a,int b)// function header the parameters no1 and no2 are called as formal arguments.
printf(" a and b in function %d and %d",a,b
a and b in function 9 and 6
a and b in the main 3 and 2.
this is a program to multiply 3 to the numbers given by the user . here we use function and the arguments are passed by call by value method.here the value of the formal arguments are altered withinthe function but no change happens to the actual arguments . the values in the main does change even after the function call.
c++ is not an operator, it is a programming language (the successor to the c programming language upon which it was based). However, if c were really an object or variable name, then ++ would be the postfix increment operator. c++ returns the value of c before incrementing c. Its counterpart, ++c, invokes the the prefix increment operator, which returns the value of c after incrementing. ++c is a convenient shorthand notation for c=c+1, which…
We can Create Programs in C plus plus without creating any object So Can we Call C plus plus A Semi-Object-oriented Programming Language?
Using normal C you cannot address a bit value. The minimum you can address is 1 byte. using embedded C you can access even abit value C is a widely used general purpose high level programming language mainly intended for system programming . Embedded C is an extension to C programming language that provides support for developing efficient programs for embedded devices . It is not a part of the C language

C++ allows you to mix object oriented programming with generic programming and C-style programming. C has none of these features. C-style programming and C programming are broadly similar, with only minor differences, most of which are irrelevant. As such, it is very rarely necessary to use a lower-level language than C++. The static type system in C is inherently weak; filled with loopholes and inconsistencies. C++ is much more robust by comparison.
