我已经尝试过检查其他答案,但我仍然找不到答案。我收到了这个错误:
compilation info
prog.cpp:192:2: error: expected unqualified-id before 'else'
else if (userInput == 3)
^
以下是代码行:
else if (userInputSolveFor == "t")
{
cout << "You are solving for time." << endl;
cout << endl;
cout << "What is the acceleration (in m/s/s)?" << endl;
cin >> acceleration;
cout << "What is the initial velocity?" << endl;
cin >> initialVelocity;
cout << "What is the distance (in meters)?" << endl;
cin >> deltaDistance;
if (initialVelocity == 0)
{
cout << "The time is " << sqrt(deltaDistance - (0.5 * acceleration)) << setprecision(10) << " seconds." << endl;
}
else if (acceleration == 0)
{
cout << "The time is " << (deltaDistance / initialVelocity) << setprecision(10) << " seconds." << endl;
}
else
{
cout << "The input you have entered is not valid." << endl;
}
}
}
else
{
cout << "The input you have entered is not valid." << endl;
}
}
else if (userInput == 3)
{
cout << "You are using vf^2 = vi^2 + 2(a)(x)." << endl;
cout << endl;
cout << "What are you trying to solve for?" <<endl;
cout << endl;
cout << "Use vf for final velocity (in m/s)." << endl;
cout << "Use vi for initial velocity (in m/s)." << endl;
cout << "Use a for acceleration." << endl;
cout << "Use x for distance (in meters)." <<endl;
cin >> userInputSolveFor;
cout << endl;
第192行
else if (userInput == 3)
我不知道该怎么做。我试过添加/删除&#34;}&#34;当我换一个支架时,我得到15个以上的错误,所以我不认为这是问题。
答案 0 :(得分:0)
从代码的这一部分看起来你有太多的结束括号,重新格式化代码并再次检查。
编辑:或者开头括号太小,无论如何,在第一个答案中,正确的格式化将帮助您。
答案 1 :(得分:0)
你的第二个其他陈述,不属于那里。如果(userInput == 3)阻止,则将其删除并在else之后输入。
答案 2 :(得分:0)
我已经解决了这个问题......我有一个太多的括号,我错过了一个括号。感谢大家的帮助,我对编码仍然很陌生,非常感谢所有的帮助。我现在正在使用Notepad ++,并且在它成为一个坏习惯之前我正在尝试学习正确的缩进。再次,谢谢大家。详细答案:
}
else if (userInput == 3)
}}没有必要,太多了
并且在另一行代码中也缺少一个括号,其中包含10多个错误。再次感谢!
