Example:
#include <iostream>
using namespace std;
int main() {
float progress = 0.0; while (progress < 1.0) { int barWidth = 70; std::cout << "["; int pos = barWidth * progress; for (int i = 0; i < barWidth; ++i) { if (i < pos) std::cout << "="; else if (i == pos) std::cout << ">"; else std::cout << " "; } std::cout << "] " << int(progress * 100.0) << " %\r"; std::cout.flush(); progress += 0.16; } std::cout << std::endl;
return 0;
}
