Which is a valid C variable declaration?Question 5Select one:a.int main;b.int $name;c.int age;d.int &temp;e.int name#;

variable is a name given to a memory location to store some value. Since the memory location can store different values during execution of a program, the name used to refer to it, is called a variable. Since variables are a part of identifiers, they follow the same naming conventions. Like identifiers, a valid variable name can start with an alphabet or an underscore ( _ ) and later have a combination of one or more letters, digits and underscores. A few examples of valid variable names are : sum,total,average_marks, etc. When creating a variable, we should mention the type of data (for example, integer or character) that it would store. This is called the data type of that variable. In a C program, variables should be declared before their usage. The format for declaring a variable is data_type variable_name;. For example: int count; // int is the data type and count is the variable name The above declaration can also be combined with initialisation. In such a case, the format for declaring a variable is data_type variable_name = constant_value;. We shall learn more about data types and constants in the later sections. Given below is an example of declaring and initialising a variable in the same line: int count = 9; // Here the variable count is being initialised to a constant value 9 Invalid #include <stdio.h> void main() { printf("age : %d", age); int age = 34; // this is the declaration statement } Valid #include <stdio.h> void main() { int age = 34; printf("age : %d", age); } Select the correct statements from the given statements. Variable is an identifier which is used to store data. The value stored in a variable is fixed. It cannot be changed once it is initialised to a value. Variable is the name given to a memory location. The type of data stored in a variable is specified by its data types.
