进度条函数 c 语言,用C++实现一个命令行进度条的示例代码

C语言进度条函数示例代码：

#include <stdio.h>

void progress_bar(int current, int total) {
    int i;
    int percentage = current * 100 / total;
    printf("[");
    for (i = 0; i < 50; i++) {
        if (i < percentage / 2) {
            printf("=");
        } else {
            printf(" ");
        }
    }
    printf("] %d%%\r", percentage);
    fflush(stdout);
}

int main() {
    int i;
    for (i = 0; i <= 100; i++) {
        progress_bar(i, 100);
        sleep(1);
    }
    printf("\n");
    return 0;
}

C++语言进度条示例代码：

#include <iostream>
#include <chrono>
#include <thread>

void progress_bar(int current, int total) {
    int i;
    int percentage = current * 100 / total;
    std::cout << "[";
    for (i = 0; i < 50; i++) {
        if (i < percentage / 2) {
            std::cout << "=";
        } else {
            std::cout << " ";
        }
    }
    std::cout << "] " << percentage << "%\r";
    std::cout.flush();
}

int main() {
    int i;
    for (i = 0; i <= 100; i++) {
        progress_bar(i, 100);
        std::this_thread::sleep_for(std::chrono::milliseconds(100));
    }
    std::cout << std::endl;
    return 0;
}
