Answer» struct <structure-tag> { <data_type> <member variable1> <data_type> <member variable 2>list of members <data_type> < member variable 3> } <structure-variable-name1>,<sttructure-variable-name2>; 1.struct: It is the reserved or keyword used in structure definition. 2. <structure-tag>: It is the name given by the programmer and used to identity the structure in future re-definitions. They are used to declare structure variables. 3. <data_type>: Any valid data type in ‘C’. 4. < member variable 1…4>: are names of the variables. 5. <structure-variable-name 1,.2>: It is used to access the members of the structure. Example: struct student { int SP regno; char name[20]; char class[5]; char combination[4]; float fees; } st1, st2, st3;

Answer»

struct <structure-tag>

{

<data_type> <member variable1>

<data_type> <member variable 2>list of members

<data_type> < member variable 3>

} <structure-variable-name1>,<sttructure-variable-name2>;

1.struct:

It is the reserved or keyword used in structure definition.

2. <structure-tag>:

It is the name given by the programmer and used to identity the structure in future re-definitions. They are used to declare structure variables.

3. <data_type>:

Any valid data type in ‘C’.

4. < member variable 1…4>:

are names of the variables.

5. <structure-variable-name 1,.2>:

It is used to access the members of the structure. Example:

struct student

{

int SP regno;

char name[20];

char class[5];

char combination[4];

float fees;

} st1, st2, st3;
