find the biggest of three numbers

/* Write a C program to find the biggest of three numbers*/

#include stdio.h
#include conio.h
#include math.h

void main()
{
int a, b, c;

clrscr();

printf("Enter the values of a,b and c\n");
scanf ("%d %d %d", &a, &b, &c);

printf ("a = %d\tb = %d\tc = %d\n", a,b,c);

}
}

{

printf ("C is the greatest among three\n");


}

/*-----------------------------
Output
Enter the values of a,b and c
23 32 45
a = 23 b = 32 c = 45
C is the greatest among three

RUN2
Enter the values of a,b and c
234
678
195
a = 234 b = 678 c = 195
B is the greatest among three

RUN3
Enter the values of a,b and c
30 20 10
a = 30 b = 20 c = 10
A is the greatest among three

This is a straight forward program. The logic is the same what we have been studying from childhood.
