You can use strtok. http://www.cplusplus.com/reference/cstring/strtok/

#include <string>
#include <vector>
#include <string.h>
#include <stdio.h>
std::vector<std::string> split(std::string str,std::string sep){
    char* cstr=const_cast<char*>(str.c_str());
    char* current;
    std::vector<std::string> arr;
    current=strtok(cstr,sep.c_str());
    while(current!=NULL){
        arr.push_back(current);
        current=strtok(NULL,sep.c_str());
    }
    return arr;
}
int main(){
    std::vector<std::string> arr;
    arr=split("This--is--split","--");
    for(size_t i=0;i<arr.size();i++)
        printf("%sn",arr[i].c_str());
    return 0;
}

In summary, there's no built-in method like with Java, but one of the users wrote this very similar method:
