Hi i'm new to C programming and need some help with writing a program.

Im trying to write a program that will read 3 numbers from the keyboard and print the largest one on the screen.

I have to only use 2 variables, 1 to read the numbers and one to hold the highest value.

I would be most grateful for any help

#include <stdio.h>

int main()
{
int xRead, xMax;

printf("\nEnter first value:");
scanf("%d", &xRead);
xMax = xRead;
printf("\nEnter second value:");
scanf("%d", &xRead);
if (xMax < xRead)
    xMax = xRead;
printf("\nEnter third value:");
scanf("%d", &xRead);
if (xMax < xRead)
    xMax = xRead;
printf("\nMax value was: %d", xMax);
}

Now, a note:  if your instructor has any grip at all, he may ask you to explain why each part of this works the way it does.  I'm going to leave that as an exercise for you.  This is pure C, not C++, so make sure that is what you are using.

Good luck.

Here is a possible solution

#include <stdio.h>
#include <conio.h>

void main(){
      int Num=0, nVal;

      printf("Enter three numbers followed by return. 0 to END\n");
      do{
            scanf("%d",&nVal);
            if(nVal > Num)
            {
                  Num = nVal;
            }
      }while(nVal != 0 );
      printf("The largest number is : %d",Num);
      getche();
}
