将max设为很小的数这个能理解，但是将max设为要比较的第一个数不知道应该在哪里入手啊，版主大大，求指导

#include<stdio.h>
int main()
{ int a[3]={0};
  int i,max=-10000000;
  for(i=0;i<3;i++)
  { scanf("%d",&a[i]);
    if(a[i]>max) max=a[i];
  }
  printf("the max number is %d\n",max);
  return 0;
}
   

#include<stdio.h>
int main()
{ int a[3]={0};
  int i,max=0;
  for(i=0;i<3;i++)
  { scanf("%d",&a[i]);
   
  }
  max=a[0];
  for(i=0;i<3;i++)
  { if(a[i]>max) max=a[i];
  }

  printf("the max number is %d\n",max);
  return 0;
}

谢谢你的帮助

 //三个数字输出最大值
#include <stdio.h>
int max(int x,int y,int z)
{
    if(x>y&&x>z) return x;
    else if(z>y&&z>x) return z;
    else if(y>x&&y>z) return y;
}
int main(void)
{
    int a,b,c;
    scanf("%d,%d,%d",&a,&b,&c);
    printf("\nThe max number is:%d",max(a,b,c));
    getchar();
    return 0;
}

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

int main(void)
{
    int value, max_value, min_value, index, result;

    printf_s("Tips: Input non digit character then <ENTER> to end program.\n\n");
    index = 0;
    do
    {
        printf_s("Please input a integer value[%d]: ", index + 1);
        rewind(stdin);
        result = scanf_s("%d", &value);
        if (result == 1)
        {
            max_value = (index == 0) ? value : __max(max_value, value);
            min_value = (index == 0) ? value : __min(min_value, value);
            ++index;
        }
    } while (result == 1);

    printf_s("\nThe max value is %d\n", max_value);
    printf_s("The min value is %d\n", min_value);

    printf_s("\nPress any key to continue...");
    _getch();
    return EXIT_SUCCESS;
}

#include <stdio.h>
#include <stdlib.h>
int main(void)
{
    int value, max, min,index;
     
    printf("Tips: Input non digit character then <ENTER> to end program.\n\n");
    printf("Please input a integer value[1]: ");
    rewind(stdin);
    if(scanf("%d", &value)==1) max=min=value;  
    else
       {
            printf("No input a data ");
        return 0;
       }
    index=2;   
    while (1)
       {
            printf("Please input a integer value[%d]: ", index);
            rewind(stdin);
            if( scanf("%d", &value)!=1) break;;
            max=max>value?max:value;
            min=min<value?min:value;
            index++;
       }

    printf("\nThe max value is %d\n", max);
    printf("The min value is %d\n", min);

    printf("\nPress any key to continue...");
    _getch();
    return 1;
}

用条件语句会不会更短！！！

貌似可以不用写这么复杂的

同为新手 一起学习吧  这是我上次写的

#include<stdio.h>
void main()
{
    int a,b,c,max1,max2;
    scanf("%d %d %d",&a,&b,&c);
    max1=(a>b)?a:b;
    max2=(c>max1)?c:max1;
    printf("%d\n",max2);

   
}
