Answer 1

#include <iostream>
#include <string>

int main() {
    std::string str = "I bought running shoes, but they started running alone, now we are both happy";
    std::string substring = "running";

    // Find the position of the first occurrence of a substring
    size_t position = str.find(substring);

    if (position != std::string::npos) {
        std::cout << "The first occurrence of \"" << substring << "\" is at position: " << position << std::endl;
    } else {
        std::cout << "Substring not found!" << std::endl;
    }

    return 0;
}
