C++中测试运行和调试运行的区别

C++中测试运行和调试运行的区别

测试运行是在写好完整的程序后，在进行检测；
调试运行是在测试运行出现错误后，无法正常的运行程序，需要进行修改而进行的调试。

#include #include #include #include using namespace std; clock_t start1,start2,end1,end2; //c-style character string implementation int main() { start1 = clock(); const char *pc = "a very long literal string"; const size_t len = strlen(pc); for (size_t ix = 0; ix != 1000000; ++ix) { char *pc2 = new char[len + 1]; strcpy(pc2, pc); if (strcmp(pc2, pc)) ; delete [] pc2; } end1 = clock(); cout << "c-style character need "<< end1-start1 << endl; //string implementation start2 = clock(); string str("a very long literal string"); for (int ix = 0; ix != 1000000; ++ix) { string str2 = str; if (str != str2) ; } end2 = clock(); cout << "c-style character need "<< end1-start1 << endl; getchar(); }
