判斷三個數的大小

# include<stdio.h>
# include<stdbool.h>

int main()
{
    int a, b, c;
    scanf("%d %d %d", &a, &b, &c);
    
    int max = 0;
    
    if(a>b){
        if(a>c){
            max = a;
        }else{
            max = c;
        }
    }else{
        if(b>c){
            max = b;
        }else{
            max = c;
        }
    }
    
    printf("max = %d\n",max);
    return 0;
