Structure type arguments in C

Structure type variables can be passed as arguments to functions. Two methods to pass structure type arguments are:

To pass each structure element as argument independently.
To pass structure type variable as argument.

To pass each structure element as argument independently

In this case Each individual element of a structure variable is passed as an argument to function.

Program to pass each structure element as argument independently.

#include<stdio.h>
struct emp
{
int empid;
float sal;
};

void show(int i,float s)
{
printf(“\n%d,%f”,i,s);
}
int main()
{
struct emp e1={101,5500.00};
show(e1.empid,e1.sal);
return(0);
}

Output

131,550.500000

To pass structure type variable as argument

In this case structure variable is passed as an actual argument to a function

Program to demonstrate passing structure type variable as argument .

#include<stdio.h>
struct demo
{
int x,y;
};
void disp(struct demo d1)
{
++d1.x;
– -d1.y;

printf(“\nd1.x=%d”,d1.x);
printf(“\nd1.y=%d”,d1.y);
}
int main()
{

struct demo d={10,15};
show(d1);
return(0);
}

Output

d1.x=11
d1.y=14
