my code:
#include <iostream>
#include <string>
using namespace std;
int main()
{
char str1[1000000];
char newString[1000][1000];
int i,j,ctr;
cout <<" \n\n Split string by space into words :"<< endl;
cout << "---------------------------------------\n";
cout << " Input a string : ";
cin >> str1 >> sizeof(str1) >> stdin;
j=0; ctr=0;
for(i=0;i<=(strlen(str1));i++)
{
// if space or NULL found, assign NULL into newString[ctr]
if(str1[i]==' '||str1[i]=='\0')
{
newString[ctr][j]='\0';
ctr++; //for next word
j=0; //for next word, init index to 0
}
else
{
newString[ctr][j]=str1[i];
j++;
}
}
cout << "\n Strings or words after split by space are :\n";
for(i=0;i < ctr;i++)
cout << newString[i];
return 0;
}

最佳答案
你需要这样做:
cout << " Input a string : ";
cin >> str1;
代替:
cout << " Input a string : ";
cin >> str1 >> sizeof(str1) >> stdin;
事实是,>> 运算符用于将输入定向到它右侧的变量。 你没有在第二个 >> 的右边给出一个变量,sizeof(str1) 是一个函数,它返回一个数字。当编译器看到一个数字而不是一个变量时,它会给你那个错误。
关于c++ - 没有运算符匹配这些操作数 C++,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/47368142/
