 Function without argument and without return type

Program :

#include
#include
void santhosh();
void main()
{
clrscr();
santhosh();
getch();
void santhosh()
{
int a,b,c;
printf("Enter the value of a and b is:");
scanf("%d%d",&a,&b);
c=a+b;
printf("The value of c is%d",c);
}

Function with argument and with return type
Program :

#include
#include
int santhosh(int a, int b);
void main()
{
int a,b,c;
clrscr();
printf("Enter the value of a and b is:");
scanf("%d%d",&a,&b);
c=santhosh(a,b);
printf("The value of c is%d",c);
getch();
}
int santhosh(int a,int b)
{
int c;
c=a+b;
return c;
}
