char pointscloud[128]; sprintf(pointscloud, "/model%d/action%d/%04dpointscloud.txt", model, action, fileIndex);
使用c++的stringstream 。
添加头文件
#include <iostream> #include <iomanip>
stringstream ss; ss << "/body3DCoordinates" << i << "_" << setw(4) << setfill('0') << j << ".txt"; cout << ss.str() << endl;
