这是我的代码,我附上了Zybooks输出的输出截图,以及我的输出结果。我试图让它输出到Zybooks所要求的东西,然而有些东西接缝是错误的。它正在编译。或者,也许Zybooks只是愚蠢?为什么程序会抱怨太多逗号?
#include <iostream>
#include <string>
#include <vector>
#include <sstream>
#include <iomanip>
#include <cstring>
using namespace std;
int main() {
string title;
string col1;
string col2;
string val;
int numCommas = 0;
vector<string> stringData;
vector<int> intData;
cout << "Enter a title for the data:" << endl;
getline(cin, title);
cout << "You entered: " << title << endl << endl;
cout << "Enter the column 1 header:" << endl;
getline(cin, col1);
cout << "You entered: " << col1 << endl << endl;
cout << "Enter the column 2 header:" << endl;
getline(cin, col2);
cout << "You entered: " << col2 << endl << endl;
while (1) {
cout << "Enter a data point (-1 to stop input):" << endl;
getline(cin, val);
if (val == "-1") {
break;
}
if (val.find(',') == -1) {
cout << "Error: No comma in string." << endl << endl;
}
else {
for (int i = 0; i < val.length(); i++) {
if (val.at(i) == ',') {
numCommas++;
if (numCommas > 1){
break;
}
}
}
if (numCommas == 1) {
stringData.push_back(val.substr(0, val.find(',')));
intData.push_back(stoi(val.substr(val.find(',') + 1, val.length() - 1)));
cout << "Data string: " << val.substr(0, val.find(',')) << endl;
cout << "Data integer: " << stoi(val.substr(val.find(',') + 1, val.length() - 1)) << endl;
}
else {
cout << "Error: Too many commas in input." << endl << endl;
}
}
}
return 0;
}
谢谢。
谢谢。
