What is a structure at local scope in C language?

Structure is a collection of different datatype variables, grouped together under a single name.

General form of structure declaration

The structure declaration is as follows −

struct tagname{    datatype member1;    datatype member2;    datatype member n; };

Here, struct is the keyword.

tagname specifies name of structure.

member1, member2 specifies the data items that make up structure.

Example

The following example shows the usage of the structure at a local scope.

struct book{    int pages;    char author [30];    float price; };

Example

The following program shows the usage the structure at a local scope.

 Live Demo

#include<stdio.h> struct{    char name[20];    int age;    int salary;    char add[30]; }emp1,emp2; int manager(){    struct{ //structure at local scope    char name[20];    int age;    int salary;    char add[50]; }manager ; manager.age=27; if(manager.age>30)    manager.salary=650000; else    manager.salary=550000; return manager.salary; } int main(){    printf("enter the name of emp1:");    //gets(emp1.name);    scanf("%s",emp1.name);    printf("
enter the add of emp1:");    scanf("%s",emp1.add);    printf("
enter the salary of emp1:");    scanf("%d",&emp1.salary);    printf("
enter the name of emp2:");    // gets(emp2.name);    scanf("%s",emp2.name);    printf("
enter the add of emp2:");    scanf("%s",emp2.add);    printf("
enter the salary of emp2:");    scanf("%d",&emp2.salary);    printf("
emp1 salary is %d",emp1.salary);    printf("
emp2 salary is %d",emp2.salary);    printf("
manager salary is %d",manager());    return 0; }

Output

When the above program is executed, it produces the following result −

enter the name of emp1:Bob enter the add of emp1:Hyderabad enter the salary of emp1:500000 enter the name of emp2:Hari enter the add of emp2:Chennai enter the salary of emp2:450000 emp1 salary is 500000 emp2 salary is 450000 manager salary is 550000
