It's a part of the program's data, which has a name,type and value.
input and output
It has nothing to do with C, it simply means: add 1 to a variable.
In the programming language C++, cin is used to input the variable and cout is used to print a certain message or result.
The term C static is a variable within computer programming in particular C Language. When set static the variable inside a function keeps its value between invocations.
For C programming, the use of a static variable has two uses: One reason is to hide the variable from other modules. The scope of the static variable is limited to the compilation unit that it is described in. The second use of a static variable is to keep the value of the variable intact through the entire program execution unit.
the simple way can be explained by example as: let there be two integers as : int a=10,b=5; if we want to use third variable then let third variable be int c; and sorting is done as : c=a; a=b; b=c; if it is to be done by without using third variable then : a=a+b; b=a-b; a=a-b; at last the variable is sorted.
with the help of pointers we able to store the memory location of any variable. In c the pointer variable is use to store the memory location of any variable. The pointer variable is define as a simple variable but in pointer variable use a special "*" character at the left most side of name of pointer variable. If any variable name have * it means it is a pointer variable it hold the memory location of variable.
A variable of which the value cannot change. Example of its usage: const int foo = 5;
It is not a reserved word, so can be an identifier (name of a type/variable/function).
Garbage data in C, or in any programming language, occurs when a variable is read without having been initialized first.
In C: int pass_mark; pass_mark = 45; In C++: int pass_mark {45};
In programming languages, a type qualifier indicates the special properties of a variable. Type qualifiers can be used for code optimization and for finding defects. In C/C++ one of the popular type qualifiers is the const qualifire. It is used to fix the value of a variable after the variable is initialized.
