c - 如何找到给三分的最高分？

Question

#include <stdio.h> 
#include<conio.h>
int main () 
{ 
        printf("Enter the Physics ,Chemistry and Maths Marks"); 
        int mark[3]= {40,50,10};
        int s[3];
        int i; 
        int sum = 0, highest = 0; 
        clrscr(); 
        for (i = 0; i < ; i++) 
             { 
                sum += mark[i]; 
                if (mark[i] > highest) 
                        highest = mark[i]; 
             } 

        printf("The Highest Mark is %d: \n", highest); 
        getch(); 

    return 0; 

} 

它工作正常，我需要动态给出输入并获取输出

如何做到这一点？

Enter the Marks : 30 20 10
output: 30

Answer 1

这个:

int mark[3];
mark[3] = scanf("%d",mark[3]);

由于多种原因是错误的。看来您不知道如何正确使用 scanf 。应该是

int mark[3];
scanf("%d", &mark[0]);
scanf("%d", &mark[1]);
scanf("%d", &mark[2]); /* Get each number from stdin and store it in the address of the variable given */

或更好

int mark[3];
scanf("%d %d %d", &mark[0], &mark[1], &mark[2]);

甚至更好

int mark[3], i;
for(i = 0; i < 3; i++) /* Loop 3 times */
{
    scanf("%d", &mark[i]);
}
