所以我有一个函数(或者更确切地说,我稍后将其转换为函数)在控制台窗口中进行随机%进度;像这样:
#include <iostream>
#include <time.h>
#include <cmath>
#include <windows.h>
using namespace std;
int main()
{
srand(time(0));
int x = 0;
for(int i = 0; i<100; i++){
int r = rand() % 1000;
x++;
cout << "\r" << x << "% completed." << flush;
if(i < 43){
Sleep(r/6);
}else if(i > 43 && i < 74){
Sleep(r/8);
}else if(i < 98){
Sleep(r/5);
}else if(i > 97 && i != 99){
Sleep(2000);
}
}
cout << endl << endl << "Operation completed successfully.\n" << flush;
return 0;
}
问题是,我希望输出如下:
1% completed
|
(稍后...)
25% completed
|||||||||||||||||||||||||
我该怎么做?
提前致谢!

打印字符'\r'
非常有用。它将光标放在行的开头。
由于您无法再访问上一行,您可以使用以下内容:
25% completed: ||||||||||||||||||
每次迭代后:
int X;
...
std::cout << "\r" << percent << "% completed: ";
std::cout << std::string(X, '|');
std::cout.flush();

我认为这看起来更好:
#include <iostream>
#include <iomanip>
#include <time.h>
#include <cmath>
#include <windows.h>
#include <string>
using namespace std;
string printProg(int);
int main()
{
srand(time(0));
int x = 0;
cout << "Working ..." << endl;
for(int i = 0; i<100; i++){
int r = rand() % 1000;
x++;
cout << "\r" << setw(-20) << printProg(x) << " " << x << "% completed." << flush;
if(i < 43){
Sleep(r/6);
}else if(i > 43 && i < 74){
Sleep(r/8);
}else if(i < 98){
Sleep(r/5);
}else if(i > 97 && i != 99){
Sleep(1000);
}
}
cout << endl << endl << "Operation completed successfully.\n" << flush;
return 0;
}
string printProg(int x){
string s;
s="[";
for (int i=1;i<=(100/2);i++){
if (i<=(x/2) || x==100)
s+="=";
else if (i==(x/2))
s+=">";
else
s+=" ";
}
s+="]";
return s;
}

使用graphics.h或使用更高级的WinBGI库。下载它,并将库文件和graphics.h文件放置在项目中的适当位置。然后只需使用名为gotoxy(int x,int y)的函数,其中x和y位于字符位置(而不是像素),请考虑您的控制台窗口在笛卡尔2D轴系统的第四象限中。但是x和y通常从1到n开始(取决于控制台窗口的大小)。每次发生这种情况时,您只需要清除屏幕即可
system("cls");
在Windows中,as cls是用于此命令。否则,对于linux / Mac,请使用
system("clear");
现在此函数在stdlib.h标头中。之后,您可以轻松地更新进度条并在其中编写任何内容。 但是您使用的进度条是不连续的。更有效率的方法是使用
# Print iterations progress
def printProgressBar (iteration, total, prefix = '', suffix = '', decimals = 1, length = 100, fill = '█'):
"""
Call in a loop to create terminal progress bar
@params:
iteration - Required : current iteration (Int)
total - Required : total iterations (Int)
prefix - Optional : prefix string (Str)
suffix - Optional : suffix string (Str)
decimals - Optional : positive number of decimals in percent complete (Int)
length - Optional : character length of bar (Int)
fill - Optional : bar fill character (Str)
"""
percent = ("{0:." + str(decimals) + "f}").format(100 * (iteration / float(total)))
filledLength = int(length * iteration // total)
bar = fill * filledLength + '-' * (length - filledLength)
print('\r%s |%s| %s%% %s' % (prefix, bar, percent, suffix), end = '\r')
# Print New Line on Complete
if iteration == total:
print()
#
# Sample Usage
#
from time import sleep
# A List of Items
items = list(range(0, 57))
l = len(items)
# Initial call to print 0% progress
printProgressBar(0, l, prefix = 'Progress:', suffix = 'Complete', length = 50)
for i, item in enumerate(items):
# Do stuff...
sleep(0.1)
# Update Progress Bar
printProgressBar(i + 1, l, prefix = 'Progress:', suffix = 'Complete', length = 50)
# Sample Output
Progress: |█████████████████████████████████████████████-----| 90.0% Complete
