有以下程序段,且变量已正确定义和赋值： for($=1.0,K=1;k<=n;k++) s=s+ 1.0/(k*(k+1)); printf("s=%¡n",s); 请填空,使下面程序段的功能与之完成相同： $=1.0； k=1; while( { s=s+1.0/(k*(k+1)); 96192034 } 2206192034 printf(*s=%An",s);

temp = fopen("temp.txt", "w");
if (fp == NULL) {
printf("File does not exist.\n");
return;
}
Student student;
int flag = 0;
while (fscanf(fp, "%d %s %s需要将 `while(` 改为 `while(k<=n)`，否则会导致无限循环。修改后的程序段 %d %f\n", &student.id, student.name, student.gender, &student.age, &student.score) != EOF) {
如下：

$=1.0;
k=1;
while(k<=n) {
    s=s+1.0/( if (strcmp(student.name, name) == 0) {
            printf("Enter new student name: ");
            scanf("%s", studentk*(k+1));
    k++;
}
printf("s=%f\n",s);

这段程序使用 while 循环实.name);
printf("Enter new student gender: ");
scanf("%s", student.gender);
printf("Enter new student age: ");
现了与 for 循环相同的功能，即计算 $s=\sum\limits_{k=1}^{n} \ scanf("%d", &student.age);
printf("Enter new student score: ");
scanf("%f", &student.score);
frac{1}{k(k+1)}$ 的值。需要注意的是，while 循环中需要手动增加 k 的 flag = 1;
}
fprintf(temp, "%d %s %s %d %f\n", student.id, student.name,值，以避免无限循环。
