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.
#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
