我的C ++代码编译并运行,但没有输出打印到控制台。我认为它与字符串变量有关,但我不确定。我是一个总菜鸟,任何帮助将不胜感激。我正在使用GNU GCC Compiler的代码块。
#include <iostream>
#include <string>
using namespace std;
int main()
{
string botlong, botshort, secondline;
botlong = "bottles of beer on the wall,";
botshort = "bottles of beer";
secondline = "Take one down and pass it around,";
for(int bottles = 99; bottles<=0; bottles--)
{
cout<<bottles <<botlong <<bottles <<botshort;
for(int lostB = 98; lostB<=0; lostB--)
{
cout<<secondline<<lostB<<botlong;
}
}
return 0;
};
答案 0 :(得分:5)
必须是>=
而不是<=
,否则您的循环不会输入:
for(int bottles = 99; bottles >= 0; --bottles)
{
cout << bottles << botlong << bottles << botshort;
for(int lostB = 98; lostB >= 0; --lostB)
{
cout << secondline << lostB << botlong;
}
}
答案 1 :(得分:0)
我认为for
循环中的条件并不适合开始。您有一个拼写错误,正确bottles<=0
到bottles>=0
,与下一个for
循环相同。
