Replace punctuation marks with spaces and uses C-string function strtok to tokenize string into individual words.

Demo Code

#include <cstring>
#include <iostream>
#include <string>

int main(int argc, const char *argv[]) {
    const char char1 = '!';
    const char char2 = ' ';

    std::cout << "Enter a string: ";

    std::string base;//from ww w.  j ava  2s.c o m
    std::getline(std::cin, base);

    size_t pos = base.find(char1, 0);

    while (pos != std::string::npos) {
        base[pos] = char2;
        pos = base.find(char1, pos + 1);
    }

    // duplicate then tokenize string
    char *dup = strdup(base.c_str());
    char *pch = strtok(dup, " ");

    while (pch != nullptr) {
        std::cout << pch << std::endl;
        pch = strtok(nullptr, " ");
    }

    free(dup);

    return 0;
}
