C Programming Structure and Function
In C, structure can be passed to functions by two methods:
1. Passing by value (passing actual value as argument)
2. Passing by reference (passing address of an argument)
Passing structure by value
A structure variable can be passed to the function as an argument as normal variable. If structure is passed by value, change made in structure variable in function definition does not reflect in original structure variable in calling function.
Write a C program to create a structure student, containing name and roll. Ask user the name and roll of a student in main function.
Pass this structure to a function and display the information in that function.
#include <stdio.h>
struct student{
char name[50];
int roll;
};
void Display(struct student stu);
/* function prototype should be below to the structure declaration otherwise compiler
shows error */
int main(){
struct student s1;
printf("Enter student's name: ");
scanf("%s",&s1.name);
printf("Enter roll number:");
scanf("%d",&s1.roll);
Display(s1); // passing structure variable s1 as argument
return 0;
}
void Display(struct student stu){
printf("Output\nName: %s",stu.name);
printf("\nRoll: %d",stu.roll);
}
