Largest Value

Question

See more:

Prompt the user to enter three integers from the standard input, read the three integers using scanf(), and display on the standard output the largest number of the
three.
Note:
· User prompt should be “Please enter three integers: ”
· The output format is “The largest value of a, b and c is m” followed by a newline, where a, b and c are the three integers inputted by the user and m is the largest of
them.

A sample run of your program is:
Please enter three integers: 23 -9 182
The largest value of 23, -9 and 182 is 182
where "23 -9 182" are user input. Note that the second output line ends with a newline so that the
cursor is positioned to the beginning of the next line on the screen after the program finishes running.

My program:
It works with most cases but when i enter 0 -900 1
it gives me 0 as the largest value. why is that?

C#

#include <stdio.h>
int main() 
{
    int a, b, c, m;
 
    printf("Please enter three integers: ");
    scanf("%d %d %d", &a, &b, &c);
    m = (a>b) ? a : b && (a>c) ? a : c && (b>c) ? b : c;
    
    printf("The largest value of %d, %d and %d is %d\n", a, b, c, m);
    
    return 0;
}

Solution 1

May be you need something as follows:
m = (a > b) ? ((a > c) ? a : c ) : ((b > c) ? b : c);

Solution 3

Why not

if (a > b)
{
  if( a > c )
    m = a;
  else
    m = c;
}
else
{
  if (b > c)
    m = b;
  else
    m = c;
}

I mean, if the ternary operator isn't mandatory...
:rolleyes:

If you want to use ternary operator there is a trick,

#define Max(a,b) ((a>b)?a:b)

#include <stdio.h>
int main()
{
    int a, b, c, m;
    printf("Please enter three integers: ");
    scanf("%d %d %d", &a, &b, &c);
    m = Max(Max(a,b),c);
    printf("The largest value of %d, %d and %d is %d\n", a, b, c, m);
    return 0;
}

You can use this macro recursively.

An "accumulating" method :) :

inline void CheckMax(int& iCurMax, const int& iCheck)
{
  if (iCurMax < iCheck) {
    iCurMax = iCheck;
  }
}

...and its usage:

{
...
  int m(MINSHORT);

  CheckMax(m, a);
  CheckMax(m, b);
  CheckMax(m, c);

  ASSERT(m >= a &&
         m >= b &&
         m >= c);
...
}

Write a c program called"Largesty of 3"that accepts three integers from the user.Your Program should then display the largest of the 3 numbers.
