 Write a program to find greater of three number using nested if else

#include<stdio.h>

int main()
{
int x,y,z;

printf("enter the three number ");
scanf("%d %d %d",&x,&y,&z);
if(x>y && x>z) //Logical operator
{
printf("x is greater");
}
else if(y>x && y>z) //Logical operator
{
printf("y is greater");

Size of variable in C

 Write a program to find the size of variable

 #include<stdio.h>
int main() {
    int intType;

  long double d;

  printf("size of short = %d bytes\n", sizeof(a));
  printf("size of long = %d bytes\n", sizeof(b));
  printf("size of long long = %d bytes\n", sizeof(c));
  printf("size of long double= %d bytes\n", sizeof(d));
  return 0;
} 

OUTPUT 

size of short = 2 bytes
size of long = 8 bytes
size of long long = 8 bytes
size of long double= 16 bytes
