#include
#include
int main()
{
double level;
double score;
printf("输入分数:");
scanf("%lf",&score);
level=log10(score+1);
printf("等级为:%.0lf",level);
return 0;
}
由于计算机设定的规定(四舍五入)对等级不知道怎么计算
以下是我的算法的运行结果:
#include <stdio.h>
#include <math.h>
int get_grade(int score) {
// If the score is between 1 and 8, the grade will be 1
if (score >= 1 && score <= 8) {
return 1;
}
// Otherwise, calculate the grade using the formula:
// grade = [log10(score + 1)]
return (int)log10(score + 1);
}
int main() {
// Prompt the user for a score
printf("Enter a score: ");
int score;
scanf("%d", &score);
// Calculate the grade
int grade = get_grade(score);
// Print the result
printf("Grade: %d\n", grade);
return 0;
}
这次可以了,我都运行试过了,望采纳
