string input = "hi everyone, what's up."
输出:
hi = 2
everyone = 8

回到Stackoverflow中的older queries ...希望这有帮助!
#include <iostream>
#include <sstream>
#include <string>
#include <vector>
using namespace std;
int main()
{
string str("Split me by whitespaces");
string buf; // Have a buffer string
stringstream ss(str); // Insert the string into a stream
vector<string> tokens; // Create vector to hold our words
while (ss >> buf)
cout<< buf<<"="<<buf.length() <<endl;
return 0;
}

#include <iostream>
using namespace std;
int main() {
string s="hello there anupam";
int cnt,i,j;
for(i=0;s[i]!='\0';i++) /*Iterate from first character till last you get null character*/
{
cnt=0; /*make the counter zero everytime */
for(j=i;s[j]!=' '&&s[j]!='\0';j++) /*Iterate from ith character to next space character and print the character and keep a count of number of characters iterated */
{
cout<<s[j];
cnt++;
}
cout<<" = "<<cnt<<"\n"; /*print the counter */
if(s[j]=='\0') /*if reached the end of string break out */
break;
else
i=j; /*jump i to the next space character */
}
return 0;
}
以下是您想要的工作演示。我在评论中解释了代码。
