Question

以下代码始终为我提供零值“计数”...

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

#define SIZE 128

int main ()

{
    char mychar , string [SIZE];
    int i;
    int count =0 ;    

    printf ("Please enter your string: \n\n");
    fgets (string, SIZE, stdin);

    printf ("Please enter char to find: ");
    mychar = getchar();

    for (i=0 ; (string[i] == '\0') ; i++ )
        if ( string[i]  == mychar )
            count++;

    printf ("The char %c appears %d times" ,mychar ,count);

    return 0;
}

谢谢!

Answer 1

这个

int const count =0 ;    

还有这个

count++;

冲突，const变量的值不能改变(这就是它被称为常量的原因)
