用于在C中查找函数调用中的已用时间的计时器

#include<stdio.h>
#include <time.h>

void someFunction() {
    // 函数内容
}

int main() {
    clock_t start_time, end_time;

    start_time = clock();
    someFunction();
    end_time = clock();

    double elapsed_time = (double)(end_time - start_time) / CLOCKS_PER_SEC;
    printf("已用时间：%f秒\n", elapsed_time);

    return 0;
}
