Structure type arguments in C

Two methods to pass structure type arguments are:

Pass structure elements as arguments independently.
Pass structure variable as argument.

To pass structure elements as argument independently

Program

#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

Pass structure variable as argument

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

Program

#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
