Answer:
1.A variable can be thought of as a memory location that can hold values of a specific type. The value in a variable may change during the life of the program—hence the name “variable.” ... A variable that holds integers (whole numbers) has the data type Integer and is called an integer variable.
2. In computer science, a data buffer (or just buffer) is a region of a physical memory storage used to temporarily store data while it is being moved from one place to another.
3.CHARACTER*n namel,name2 where name1 and name2 are n characters in length each. CHARACTER namel*nl,name2*n2 where name1 is of length n1 and name2 iS of length n2. Constants are quantities whose values do not change during program execution. In FORTRAN they may be of numeric or character type.
4. Arithmetic Operators: Arithmetic operators are used to perform arithmetic/mathematical operations on operands. Division ('/'): Divides the first operand by the second. Increment ('++'): Increment the value of an integer.
5. Variable-binding operators are logical operators that occur in almost every formal language. A binding operator Q takes two arguments: a variable v and an expression P, and when applied to its arguments produces a new expression Q(v, P).
6. In computer and machine-based telecommunications terminology, a character is a unit of information that roughly corresponds to a grapheme, grapheme-like unit, or symbol, such as in an alphabet or syllabary in the written form of a natural language.
